Natural circulation Reciprocating Grate Steam Boilers combustion equipment adopts reciprocating grate. It is a simple structure, convenient.

Natural circulation Reciprocating Grate Steam Boilers combustion equipment adopts reciprocating grate. It is a simple structure, convenient.
Natural circulation Reciprocating Grate Steam Boilers Adopt the type of double-drum natural circulation water-tube, The furnace water wall tubes around the room layout to absorb radiant heat, it forms membrane wall water-cooling furnace. Chamber before and after the membrane water-wall tube to the lower part of the wall to stretch in the furnace respectively, it forms the arch above the grate , Natural circulation Reciprocating Grate Steam Boilers which increases the sealing performance of the boiler and the heating surface of the furnace, while reinforcing the strength of the arch after. Former and back arch to the fire after pouring refractories, to reduce heat absorption, to form high temperature area, it is enabling combustion of the fuel.

Furnace wall water-cooled wall tube in furnace export smoke window Department is pulled into two row, it constitutes coagulation slag bundle with boiler bundle.Flue gas through a baffle lateral scour convection tube from the bottom up. After cooling ,flue gas enter the boiler tail flue, scour tail-heating surface, through iron coal saver and air pre-heater, and then discharge furnace, into the dust collector, finally from chimneys into the atmosphere.

Natural circulation Reciprocating Grate Steam Boilers combustion equipment adopts reciprocating grate. Due to the moving grate push feed, It can mix the burning and unburned fuels, it is greater grate ignited. Grate the push feed also play the flames . Natural circulation Reciprocating Grate Steam Boilers Because fuel particle wipe ,the outer layer of ash in coke-start fall off, the movable grate in while feeding also crush cinder blocks, which can make fuel better burn. It is a simple structure, convenient, smoke effects, smoke and low dust content.

Natural circulation Reciprocating Grate Steam Boilers adoptbalanced ventilation blowers and induced draft fans mode, it maintains negative combustion pressure 20Pa in the furnace, it is under negative pressure in the flue,it is conducive to environmental health.

We take the example of SHW15-1.25-H , Natural circulation Reciprocating Grate Steam Boilers . The design of boiler parameters:

()rated evaporation capacity: 15t/h

()rated steam pressure: 1.25MPa

()rated steam temperature: 194°C

()feed water temperature: 105°C

()air temperature: 30°C

()flue gas temperature: 132 ℃

()discharge rate: 5%
