1020 kw horizontal natural gas hot water boilers
Fast one side condensing boiler steam condensate integrally advanced technology, with high efficiency, appearance, durable, cost savings, reduced noise, low nitrogen environmental advantages; self-developed by use of flue gas condenser waste heat boiler greatly increased thermal efficiency, while reducing emissions of harmful substances, can save a lot of fuel, compared with ordinary boilers, the average annual fuel cost savings of several million. Fast and well-equipped boiler unique cloud service 3.0 system, through remote monitoring of boiler operation, all-round ensure the safe operation of boiler.
70MW DHL series coal-fired 1020 kw horizontal hot water boilers for a heating power company
ZOZEN DHL series coal-fired watertube hot water boilers are ideal equipment for central heating. This series of boilers are forced-circulation, single-drum horizontal chain grate hot water boilers. Membrane water walls are arranged around and in the middle of the furnace to absorb the radiant heat of high-temperature flue gas in the furnace. And the large furnace extends the residence time of the flue gas in the furnace, making the fly ash and combustible gas be fully burned, which not only improves the thermal efficiency, but also greatly reduces the amount of fly ash and the original emission concentration of the boiler. The boiler arch adopts the scientific and technological achievements of the Xi'an Jiaotong University's to ensure the combustion effect of inferior coal and expand the coal adaptability. Boiler grate adopts bar grate to improve the operation safety. Through stepless speed regulation, users can adjust the load arbitrarily without affecting the thermal stability of combustion.
Depending on the operating characteristics of electric steam boilers, mainly to properly regulate the drum and induced draft fan. The chamber negative pressure is guaranteed ± (5-10) premise mm water column (water column ≈9.8Pa 1mm) to minimize the amount of the wind, to extend the residence time of the flue gas temperature in the furnace, reduce exhaust gas temperature.
Coal fired circulating fluidized bed 1020 kw horizontal hot water boilers has simple and compact structure, the boiler body consist of combustion equipment, coal feeder, water cooling system, separators, economizers, air pre-heaters, steel frame, escalators, furnace walls and other components, adopt full steel frame.Coal fired circulating fluidized bed hot water boiler from the front to back are arranged in order as combustion chamber separators, tail flue, to ensure good sealing performance, high temperature zone with membrane wall sealing structure, all suspension type, fixed expansion center, dip leg is integrated with the furnace water wall for expansion, improve operating reliability and reduce heat loss, Before furnace is the coal feeder, combustion required air provided by the first and second fan, fuel combustion in the furnace produce flue gas that carrying some fuel, the separator is used to separate flue gas and fuel, the fuel through separation back to the combustion furnace. By adjusting the amount of coal, the primary air and secondary air flow rate and ratio, bed inventory, you can easily adjust temperature inside bed.
