Industrial plant low pressure high thermal efficiency rice husk boiler prices cleaning method which: industrial plant boiler cleaning method What? For industrial boiler plant, the run for some time are to work descaling, if not timely cleaning, for normal operation of the industrial boilers, will have a great impact. Clear boiler scale methods, mainly mechanical descaling and chemical descaling two kinds. Mechanical descaling by the people directly into the drum, spatula or heating surface cleaner to remove scale. However, this method is labor intensive, easily damaged heat transfer surface roughness increases heat transfer surface, not completely clear, it has been rarely used. Chemical cleaning commonly used cleaning and corrosion hydrochloric acid two alkali cooking method, cleaning method which should be taken according to the kind of fouling layer. Alkali cooking method is run in the soda furnace (of Na2CO3), caustic soda (NaOH), or trisodium phosphate, longer times boiling out at normal operating pressure.

Standard gas low pressure high thermal efficiency rice husk boiler prices flue gas temperature, the abnormal temperature rise control method of treatment and a heat loss, the temperature of exhaust gas boiler 1. The state does not require a standard exhaust gas temperature, but there is a predetermined low efficiency. 2, the boiler exhaust gas at high temperature of about 120-180 degrees, the higher the exhaust gas temperature is low boiler efficiency. 3, the non-condensable exhaust gas temperature 180 degrees in the art (GB shall not less than 110 degrees) and a thermal energy conversion efficiency of the exhaust gas temperature, but also on the air coefficient and so on. Second, what factors will lead to gas-fired boiler flue gas temperature rises, there is a high gas-fired boiler flue gas temperature problems during use, gas-fired boiler flue gas temperature high will reduce the thermal efficiency of the boiler, in order to solve the exhaust gas temperature excessive problems, to understand the reasons for the high temperature exhaust gas boiler? is caused by the high temperature exhaust gas boiler does what reason? 1, the heated area ash, slagging. Heat Surface Slag cause heat deterioration, deterioration of the cooling effect of the flue gas, the exhaust gas temperature. 2, when the excess air ratio and gas boiler leakage coefficient is too large, excess air increases with the same impact. 3, gas boiler feed water temperature rises. Economizer heat transfer temperature difference decreases the exhaust gas temperature rises. 4, the fuel property. When the fuel is added water, the amount of flue gas increases, the exhaust gas temperature rises. Low volatile fuels, high ash content, so that delayed ignition, the exhaust gas temperature rises. 5, combustion and air distribution mode. Combustion air distribution mode change, the furnace may lead to shift the center of the flame, the exhaust gas temperature rises. 6, when the gas boiler furnace negative pressure is too large, the smoke quicker, increase the coefficient of air leakage, the exhaust gas temperature. 7, bottom seal gas boiler water interrupted, leakage increases and the shift of the center of the flame, the exhaust gas temperature. To understand the reasons for the high temperature exhaust gas boiler, the reason to start to solve the problem of high boiler flue gas temperature, thereby increasing the thermal efficiency of the boiler. Third, the high temperature exhaust gas boiler solution 1, see the burner power with power boiler match. Burner power is too large, the transfer of small gas flow on the line. 2, check the wind volume is too large. Adjusting the amount of the wind, the oxygen content of the combustion ratio at a reasonable gas boiler the exhaust gas temperature decreases, combustion energy. Fourth, an effective method of controlling exhaust gas heat losses of the boiler size, flue gas heat loss factors determines the size of the three: the exhaust gas temperature, excess air coefficient, and the cold air temperature. Wherein the excess air ratio of gas boiler is a major factor. Excess air ratio is too large is a large waste. A lot of cold air into the furnace, reducing the furnace temperature, combustion conditions become unstable, but also increases the flue gas volume, increased heat losses. Calculations show that when the excess air ratio is increased to 3.0 from 2.0, heat losses to 4.5%. While increasing the drum Fan burden, so power consumption increases. In order to improve the gas boiler thermal efficiency, we must pay attention to and raise awareness of the serious dangers for the high excess air ratio caused by combustion in the regulation strictly control the excess air ratio, the key to avoiding excess air furnace is reasonable with the wind and with adapted to monitor control. Monitoring means are CO2 or O2 content measurement method for measuring oxygen gas boiler is usually carried out, because the combustion of gas boiler a slight positive pressure, the seal is easy to solve the problem, the oxygen content is measured more accurately reflect the excess air coefficient values. Oxygen measurement techniques now commonly used zirconia-type oxygen analyzer constant temperature, continuous on-line measurement of the oxygen content of the flue gas. The flue gas oxygen content as a reference, the correct air-fuel ratio adjustment, a low oxygen combustion. About an effective method of controlling the size of the exhaust gas boiler heat loss, current advanced technology to automatically adjust the combustion process of oxygen combustion of PLD, followed by fine-tuning "two" that the throttle damper, to ensure normal combustion, black smoke, excess air ratio as small as possible, usually to achieve the above two points, the excess air ratio is close to the threshold. The current new generation of gas-fired boiler has been relatively safe, if you want to understand the use of gas-fired boiler, price, type and other information, please contact us.

The difference between hot water and steam low pressure high thermal efficiency rice husk boiler pricess of the boiler as a heat medium for air conditioning, heaters, low temperature oven drying equipment, textile and the hot water tank is heated by a variety of low-temperature, heat transfer and air-conditioning coil equipment. Hot water as a heat medium has the following advantages: 1. Generally the lower the heat medium water temperature of the heat medium, and large temperature difference between the flue gas, boiler exhaust gas temperature is relatively low, and thus higher boiler efficiency. 2. Closed hot water supply system small amount of water and sewage rate is much smaller than the steam boiler, waste water is also smaller. And lower boiler water quality requirements, less the cost of water treatment. 3. The specific heat capacity of water is large, a large hot water system capacity, strong heat storage capacity. When the thermal conditions or hydraulic failure condition a short time, without significantly heating conditions cause large fluctuations. 4. pump hot water heating system can be used for long-distance transportation, a small heat loss, heating large radius, to adapt to the requirements of urban planning central heating. The hot water temperature is low, less heat transfer coefficient, thermal efficiency is relatively low as the heat medium heating major drawback. Present predominantly of boiler steam boiler, steam as a heat medium main advantages are: a low cost, wide adaptability, can meet the heat requirements of the various users have different requirements for temperature and pressure simultaneously; 2 nontoxic. directly heating food, even if leaking would not harm the environment; 3 high steam temperature, a large latent heat of vaporization, the heat transfer area can be reduced relative to the hot water device, reduce costs; 4 hot inert small, heat faster when the steam supply, the cold disappear just as quickly when the steam stop. Since the heating medium steam condensate recovery is difficult, resulting in waste and water latent heat. Even with condensate recovery, condensate recovery in the process, because water easily dissolved oxygen and other impurities, but also easy to cause harm to the boiler. Oxygen to the water, salt and other impurities cause boiler fouling, corrosion and other problems affecting the safety and energy efficiency of the boiler.
