double drum biomass boiler, 1 water tube double boiler barrel boiler, 2 big furnance ,high efficiency, 3 Grade A pellet boile - details see: https://www.machineto.com/new-energy-conservation-double-drum-biomass-boiler-10212008

new engergy conservation double drum biomass boiler

SZL is assembling water tube steam boiler and double boiler barrel longitudinal type chain grate steam boiler ,

which is make up of steam drum ,water drum ,convection bank ,there are light pipe water wall tubes in two sides

of combustor. Inside of steam drum ,there is steam and water separation device ,and surface drainage device ,

inside of water drum there is regular drainage device,the economizer is at the end of boiler .Matted chain grate to

feed coal or biomass and equipped with blast blower , induced draft fan ,spiral slag discharge machine to discharge

slag automatically, the fuel from coal scuttle fall into fire grate to burn in the combustor ,flam pass through combustion arch to

refract up ,through boiler combustor bend to convection bank,then pass back smoke exit to economizer and dirt catcher,finally with

induced draft fan to flue to atmosphere.

Boiler feature:

1.This boiler divide into two pieces to ship ,the upper piece include the boiler body ,upper furnace wall ,

the bottom piece include coal scuttle ,chain grate ,base steel ,the bottom furnace wall ,except the midfeather

is setted on the scene ,the other parts is assembly in the factory ,the economizer ,and the air flue is following the boiler

2.Adopt chain grate ,double side in the wind ,there are six independent wind chamber below the fire

grate ,in the room with the wind agencies on both sides ,The air is blowed by air blower into the bottom

to two side wind flue ,through wind agencies into independent wind room. their iscylcone combustion,high temperature high speed revolution ,mixed combustion ,ash ,dust separate inside ,so boiler body dust remover is Grade A .Avoied burnng is not enough .

3.The upper furnace wall is assemble in the factory ,the bottom furnace wall and the front and back arch

is made up of fireclay brick and silicate fiber ,and thermal insulation material .,the fuel from coal scuttle to fall into

furnace to burn ,the slag is following with the chain grate to discharge by slag machine.Easy to install and 98% good dedusting ,convenient to deslag .

4.There is electrical cabinet which show the boiler thermal parameter indicator ,air blower ,induced draft fan opening

indicator gauge ,electric actuators remote control button ,the automatical feed water device ,and super temperature alarm device

5.furnance volume isbig,any fuel is avaiable.So it save your fuel cost .

6.big heating area,quickly increase pressure ,and capacity is very enough .Lowenergy consumption .

7.there isgood safety device,there are Spring safety valve and bimetal temperature gauge and high-low water level gauge alarm .It is easy to oberve the boiler working ,meanwhild there isautomatica operating system..
