How to maintain the boiler during operation of the boiler during operation how to maintain water supply and water quality monitoring furnace boiler feed water and boiler water boiler maintenance ⑴ should be consistent with GB / T1576-2008 "industrial boiler water quality" standards. And regularly sampled for testing. The number and frequency of emissions is determined by laboratory personnel. Laboratory and sewage should be detailed records. ⑵ mechanical rotation monitoring for pumps, fans, pumps, etc. to be employed a method of three touch see two monitors. Abnormal phenomenon, that approach to take. If necessary, to shutdown maintenance, are not the effect. ⑶ daily oil tank oil level monitoring if no automatic control device, the oil level should be checked regularly and found that the oil level is too low, the use of two hours is not enough, please notify the staff in advance of the fuel injected new fuel. ⑷ soft water tanks commonly used to control the operating state of the automatic control device ⑸ To periodically check the water treatment apparatus to the ion exchanger is failed, or periodically backwashed. ⑹ monitor the exhaust gas temperature under normal circumstances, the new boiler is generally lower exhaust gas temperature, with the increase in run time will gradually increase. If it is found that the change is too large and exceeds 20 ℃ (algebraic difference), you should select the appropriate cleaning shutdown time. If this phenomenon occurs very frequently, it will have to check whether the normal combustion system. The oil pressure is too low, resulting in poor atomization low oil temperature, oil or wind than not, resulting in poor fuel air mixture so that the char combustion analysis hypoxia. Further, the dry back boiler, if the exhaust gas temperature increased abruptly, it is possible to return in a compartment between the second and third after the smoke box backhaul firewall leak smoke, shutdown would need repair.

Henan gas boilers What are the advantages to meet the heating and hot water supply Henan gas boiler fueled by natural gas, heating water through the burner to achieve heating and provide life bath with hot water, high degree of intelligence boiler, heating fast, low noise, no dust, is the economy in a very hot boiler varieties suitable for China's national conditions. Henan gas boiler heating alone can not only meet but also to meet the supply of hot water alone, if the piping system to increase the heat, then you can meet both requirements simultaneously heating and bathing. 1, the system control microcomputer controller for fired horizontal hot water boiler for hotel configuration, large-screen full Chinese LCD screen with bright backlight, day or night, the boiler operating state is clearly visible. 2, the combustion system, automatic programmed control Henan gas boiler, the fan automatically purge electronic auto-ignition, spontaneous combustion and gas, (air) to automatically adjust the proportion of oil wind, good atomization, combustion, energy saving, have flame protection combustion device to ensure safety. Under normal circumstances, the combustor output temperature of the boiler with the combustion flame length is automatically adjusted, the outlet temperature of the boiler reaches the set value, the burner combustion is automatically stopped, when the temperature is below the set value, the burner is automatically started. When the abnormal phenomenon of the fuel, air intake, fault lights, the output sequencer will immediately stop the fuel, burner shut down automatically. 3, furnace design, structural design according to atmospheric pressure, with the top through the large pores, Henan gas boiler operates at atmospheric pressure, away from the danger of explosion; boiler furnace using computer simulation to optimize the design, the size of the boiler is fully optimized, so that form beautiful coordination. 4, multiple protection, Henan gas boiler having multiple security: the drain leakage protection that is automatically cut off power; i.e. overheat protection boiler water temperature reaches ultrahigh temperature alarm, automatic stop and alarm the burner; i.e., the second thermal protection temperature exceeds the boiler shell when 105 ℃, automatically cut off the secondary circuit, the boiler is stopped; i.e. excellent anti-dry protection level real-time monitoring water level electrode rod, for other reasons, the boiler water level is reached below the low water level, the boiler is stopped, to prevent the occurrence of dry Danger. 5, thermal insulation performance, glass wool insulation for whole body type, light weight, good thermal insulation effect, and less heat loss. 6, the overall appearance of the white color board packaging, nice, closed Haonai corrosion, mechatronics, small footprint, and easy to use.

In response to the call of the State Environmental Protection Department, to further improve air quality, enhance people's happiness blue sky, located in Leshan City, Sichuan Province of the energy restructuring and clean coal-fired boiler as the primary task of air pollution control, to promote the elimination of coal-fired boilers remediation work. According to statistics, from January to October this year, Leshan City, the main urban air quality index improved 11.86 percent year on year, a figure that ranked third in the province; a few good days of 251 days, an increase of 29 days, compliance rate of 82.57%; PM2.5 average concentration of 44.5 micrograms / cubic meter, an improvement of 14.09%; PM10 average concentration of 69.0 micrograms / cubic meter, an improvement of 5.74%. Improve these figures can not be separated Leshan Municipal People's Government's strong support and initiatives. Leshan municipal government adhere to precise planning, but also a public green, clean living environment.

A careful planning. Since 2017, vigorously promote energy restructuring and transformation of coal-fired boilers, in-depth investigation status of the city's coal-fired boilers, having accurate number of the city's coal-fired boilers, steam tonnage and treatment facilities, the establishment of coal-fired boilers ledger. To promote the implementation of the "coal to electricity", "coal to gas" projects the city's key industries, coal-fired boilers to transform, adjust the expansion of high-pollution fuel combustion zone ban.

Second, the fine classification. Classification of coal-fired boilers to carry out renovation work, from the source strict control of new coal-fired boiler, new and expansion projects to encourage the use of electricity, natural gas and other clean energy; with the implementation of small coal-fired boilers eliminated, medium and large transformation. The city 10 steam tons / hour or less and a total of 717 small coal-fired boiler units are all clear, a total of 1030 tons of steam. Medium-sized coal-fired boiler clean energy transformation or transformation in accordance with the deadline for ultra-low emission "should gas is gas, should the electric power" principle, Taiwan is currently the city's 44 large and medium sized coal-fired boiler clean energy transformation has been completed and ultra-low emissions transformation.

Third, the precise advance. Strengthening full control of behind schedule inspectors to speed up reform. Strengthen financial subsidies, to boost the progress of work, more than 7 million arrange special funds for the transformation of the atmosphere and medium-sized coal-fired boiler subsidy, cities, counties (cities, districts) to finance 20 steam tons / hour and clean energy alternative to coal-fired boilers the implementation of special subsidies.

In order to ensure boiler safety, to run smoothly, you must ensure that the use of high-quality natural gas. 1, equipped with one gas separator to increase the capacity, it can effectively store oil and water. Secondly, a level gauge designed to directly observe whether there is liquid in the separator. While the design of the automatic drain pressure relief device is installed. A single control pressure of the air is improved dual control, i.e. the pressure regulating valve is mounted on the main line to control the water separator, the pressure to stabilize, improve security purposes. 2, safety monitoring natural gas as a boiler room burning materials, natural gas leak monitoring must be done. The portable display technology poor performance, poor sensitivity. Host combustible gas alarm system with digital control scaling circuit having an alarm function and a secondary alarm, ensure the safe operation of the boiler. 3, check before firing the safe operation of: (1) whether the boiler inspection gates normally open or closed, check the gas pressure is normal, not too high or too low, open the supply valve leading to the boiler. (2) in the flue baffle must be fully open, otherwise it will affect the purge, causing accidents. Each knob and keep control cabinet to check the normal position. If the stove has a residue should be cleaned. (5) Check the boiler ignition and fire protection program control means should be flexible and reliable. Blast doors should be flexible and rigorous on the boiler. Before the completion of ignition, the ignition is not possible to start the ignition operation: After successful ignition, the load can be adjusted in the normal operation of the boiler when the combustion gas boiler adjusted. We should always observe the combustion furnace, and adjust the amount of steam, wind and steam pressure to ensure the safe operation of the boiler. Note: Program: first five minutes were furnace cleaning, automatic ignition after 5 minutes, observe the ignition is successful, the success of one minute after a small fire can be operated automatically converted to fire properly. For the boiler load and the air pressure adjusted by adjusting the pressure regulator to achieve. When adjusting the load, adjust the air pressure at the same time, it must be synchronized to adjust the air flow to ensure a reasonable match air volume and air volume, in order to achieve economic operation of the boiler. In normal operation, the amount of gas should not be adjusted or reduced drastically in order to avoid dramatic changes in combustion, the pressure receiving member sudden expansion, shrinkage and damage. When the boiler is running, the pressure gauge must be monitored regularly in order to maintain stable water pressure. BCP pressure changes observed, reflecting the relationship between water temperature and steam consumption. In the boiler operation, when the steam pressure is automatically adjusted, the main purpose of the staff is to monitor automatically adjusts the boiler system is sensitive and timely solutions to problems and ensure the sensitivity and reliability of the automatic control system. 4, first close the main valve shutdown operation, the air supply is stopped, the circulating pump and the water pump is still running, when the boiler water temperature falls below 70, and supplies or stops the circulation pump in operation of the pump after about 4 hours. Note: In addition to the accident and emergency parking stop, parking general approach should not cut off the power. After the shutdown, it is timely for the boiler and ancillary equipment to conduct a comprehensive inspection. If you find a defect in the device, and repair should be recorded at the time of shutdown. Safety Precautions 1. burner startup, if the burner is repeatedly locking and alarm, you should find out the cause of the malfunction, press the reset button after troubleshooting, press the reset button and then continue to boot. Note: Press the Reset button for less than 10 seconds. A lower burner inlet must be clean and clean, and does not allow offal. 2. burner once the ignition is unsuccessful, Boiler Fan should be restarted. Ventilation After 5 minutes, start the second startup burner igniter. three. During normal operation, the thermal device near the burner portion (e.g. flange connections) will be very hot, in order to avoid burns. Do not put flammable materials in the vicinity so as not to cause a fire. 4. The operation of the boiler circulating pump must be closely monitored and the fired horizontal hot water boiler for hotel pressure, gas distributor, pipeline valves, pressure gauges, flow meters, water level gauge and the like. 5. When the firefighters open the door or fire door observation, you should wear gloves and a side view. 6. A burner working environment should be kept clean and dry, in particular, a flame detector (i.e. electric eye) should be kept clean, part of the control circuit should humidity and temperature; class should cleaning and maintenance of a combustor. 7. During use, the filter should be cleaned regularly check or replace the filter cartridge in accordance with impurities of the fuel. 8. Check the electrical installations include: wire is damaged, the sheath is damaged, the screw is loose, the contact is good, whether the motor is running abnormal noise. Describes the advantages and disadvantages of natural gas boiler, editor of Sin sets introduced, the use of technology and safety precautions. Industrial boilers to energy efficient, environmentally friendly development direction. Natural gas boiler to meet the needs of these three points. They are the future of the boiler market trend, more and more restricted energy policy, energy saving and environmental protection requirements.
