DZL series industrial coal hot water boiler

Industrial boiler energy saving measures which are currently the main problems of industrial boilers have low thermal efficiency of boilers, energy can not be effectively utilized, resulting in waste; old boilers, automatic control level is not high, affecting boiler combustion efficiency; energy-saving regulation in place, and many other issues . In order to prevent pollution of the environment, reduce energy consumption, industrial boiler energy saving technical measures as follows: (1) the transformation of coal to the device. The modified ingredients bucket coal to the coal layer, using gravity filtering, the pulverulent raw coal, lump coal from top to bottom on the grate loosely distributed, facilitates air intake, improve combustion, improve the combustion rate of coal, reduced ash carbon content. (2) the transformation of the combustion system. For forward Stoker, the transformation from a combustion system is injected into the furnace in place an appropriate amount of pulverized coal to the furnace in place, so that the combustion grate base layer, the increase amount of suspension firing. (3) the transformation of furnace arch. According coal actually used, appropriately changing the shape and position of the furnace arch, can improve combustion, improve the combustion efficiency. (4) Transformation of grate-fired boiler circulating fluidized bed boiler. Employ a circulating fluidized bed boiler is a pulverized coal boiler in the furnace of the circulating fluidized combustion mode, which is 15-20% higher than the thermal efficiency of the boiler burning layer. For a variety of coal, limestone powder may be used in the furnace desulfurization, greatly reducing the content of the flue gas emissions of S02. Using (5) inverter technology, auxiliary boilers transformation. (6) The automatic control system, real-time adjustment of the heat output of the boiler, to save energy. (7) recovering the condensed water. (8) boiler replacement, replace old boiler with a new boiler. (9) flue gas discharge system reform.

Henan how boiler manufacturers mainly clean gas boiler Henan boiler manufacturers boiler after a long run, the inevitable emergence of scale, the problem of corrosion, boiler manufacturers Henan boiler scale formation in water having a hardness of a composition, high temperature and high pressure after concentration continuous evaporation, a series of physical and chemical reactions in the furnace, the final formation of hard, dense scale on the heating surface, resulting in reduced heat transfer and the effect of corrosion under the scale factors, can cause Henan boiler waterwall boiler manufacturers endothermic reduction furnace, furnace outlet temperature of the boiler is increased, so that an increased loss of Henan boiler manufacturers boiler. While the effect of reducing the fouling of heat transfer within the water wall, the tube wall temperature may lead to increased lead Wall Wall squib, Henan Effect of boiler manufacturers safe operation of the boiler. Scale is "detrimental of the first" boiler, the boiler is the main cause of accidents, the danger main problems: wasting a lot of fuel: Because only one of very few steel thermal conductivity of scale, so when the heating surface fouling will transfer hindered, in order to maintain a certain boiler output Henan boiler manufacturers, it is necessary to increase the temperature of the side of the fire, so that the external radiation and flue gas heat loss. Now can be used efficient and environmentally non-corrosive cleaning agent for cleaning the gas boiler, so that the exposed metal tube device primaries, and to reduce biological fouling of algae because silt impact. At the same time stripping the role of iron oxide and iron oxide Asia, extended gas boiler service life, reduce energy consumption and improve productivity. Henan the maintenance of the boiler gas boiler manufacturers: 1, Henan boiler manufacturers during operation of the gas boiler the following points should be noted: (1) Henan boiler manufacturers do not allow pressurized gas boiler furnace combustion or smoke, plus easy to burn because coal hole covers. Not on the bottom of the water (2) Gas boiler ground surface to prevent moisture corrosion. 2, operation of the gas boiler boiler factory in Henan every 2-3 weeks, should be checked once. 3, run gas boiler boiler factory in Henan every 3-6 months after the shutdown should conduct a comprehensive inspection. (1) on the inside and outside gas boiler inspection, such as pressure welds, corroded steel inside and outside part of the phenomenon, if found should be repaired in a serious flaw, if the defect is not serious next time also to be shutdown to repair, if found when there is suspicious, but does not affect safety, records should be made for future reference. (2) can be checked and the water boiler primer coating to prevent corrosion.

Exhaust gas temperature factors affect the efficiency of the boiler 1. High boilers (1) ring-shaped heating surface. A protective pot operation due to the heated area ash causing poor heat transfer. Secondly heating surface by erosion wear of the high temperature flue gas, resulting in good convection bank vent for taking soil pipe powder blocking manner with less number F, powder powder increases the number of block f will inevitably result in decreased heat transfer effect of the heating surface, the deterioration of the operating parameters. such that the exhaust gas temperature medium (2) bits leakage furnace, the burner burning roll. Wind refuse mud furnace, burner combustion burning material will travel in incomplete protection technology, resulting in frameshift flame, which led to the degree of BU smoke Mi (3) poor operating conditions. A secondary air must have appropriate warehouse Shan ratio during burning. Secondary air Diao large ring-shaped hold burning effect, will affect the wind. Powder mix. 2. boiler water quality factors is an important indicator of pot care, but also a very appropriate to link, the water quality directly affects the safe and economical operation of boiler protection, internal cleaning of the heating surface of each pier can add endothermic t, It will increase the efficiency of the care of the pot. Shanghai each newly installed boiler heating surfaces are clean, the indicators are good, heat transfer efficiency is higher. But with longer run time, the inside of the tube or bi or furring rights corrosion, resulting in decreased heat transfer efficiency, pot nursing efficiency drops, after scaling or corrosion deterioration. Pot can also cause over-temperature protection wall even Los iron . 3. mechanical incomplete Tanzania Heat loss if the twist burner for burning Yan basin, coal dust mixed into the retaining find not carried out, resulting in insufficient fuel you burn. Shan increase mechanical incomplete burning loss. On the other hand due to air leakage protection Mu. Mi will lead to reduced care. Shan burn rate of decline. Powder fire longer, is not conducive to coal combustion rate, resulting in an incomplete tender burn solid increase in losses. Division personnel to operate the operation level of the level 4. 0 operator is not high, not be reasonably performed with the wind, the rotation speed control discharge protection, timely cleaning, descaling, resulting worthy material is not completely burned proud. Long low thermal efficiency in the actual operation, often occurs due to the experience of the operating personnel, resulting in decreased operating efficiency of the unit, adjust the low level of security decline. 'On the other hand, there is a difference operator P forced cultural quality and the level of practical skills.
