DZL type chain grate steam boiler is a kind of horizontal three-return water and fire pipe mixed steam boiler, which is arranged with a bunch of threaded smoke pipe inside the boiler barrel.The left and right sides of the furnace chamber are equipped with water cooling walls of light pipes.It adopts light chain grate to realize mechanical coal feeding, equipped with blower and induced draft fan for mechanical ventilation, and equipped with scraper type slag discharge machine to realize automatic slag discharge.The front and rear arch of the steam boiler adopts new energy saving technology.After the fuel falls on the grate from the coal sill and enters the furnace for combustion, the flame, through the refraction of the rear arch, turns upward through the burning Chambers on both sides of the body and turns to the front smoke box, and then turns back to the tube bundle in the pot by the front smoke box, enters the economizer through the rear smoke box, and then is pumped by the induced draft fan to the air through the flue to the chimney.

Burning process of Biomass Fired Boiler 

Fuel falls from coal hopper onto the front of chain grate, moves along with the chain grate and will be preheated, dried, ignited, burned out. Slag will be discharged by slag remover(eliminator) at any time. Herring bone arch is adopted to improve igniting condition. Smoke forms between front and back arches vortex, completely mix with air, burns out and then goes after each other through smoke flue at two wings, front smoke box, threaded smoke tubes, cast iron economizer(for hot water boiler no cast iron economizer), dust remover, draft fan and will be emitted through chimney.

Performance Features:

1. The biomass steam boiler is a horizontal fast-loading steam boiler with natural circulation of working medium.The heat exchange system of the steam boiler is composed of the boiler barrel, the left and right sets, and the water cooling wall. The main heating surface has the water cooling wall of the furnace, part of the boiler barrel and the convection tube bundle inside the boiler barrel.This series of steam boiler is composed of five parts: boiler body, smoke duct, dust collector and pipeline system.The first four parts have been manufactured in the factory and transported to the installation site for assembly, which can greatly shorten the installation cycle and ensure the installation quality of products.

2. Excellent boiler design performance: the main heating surface tube of the steam boiler is made of seamless steel tube of no. 20 low and medium pressure boiler, and the boiler barrel is made of special steel plate for the boiler.The left and right containers are made of seamless steel tubes.

3. The coal fired steam boiler arch is made of fire-resistant concrete.The rear arch is low and long, so it burns well. The wings of the flue and the side wall tiles are made of refractory sintered bricks.Boiler front wall and back wall adopt universal firebrick.

4. Reasonable blast distribution of boiler grate, large combustion chamber and strong applicability of coal.Suitable for all kinds of bituminous coal or anthracite, mixed coal.Full combustion. As the high-temperature smoke enters the settling chamber and then enters the two wings of smoke flue and front smoke box from both sides, the effect of smoke elimination and dust removal is good.

5. Simple water circulation, reasonable structure of pressure components, under the condition of ensuring water quality, completely safe operation.

6. The steam boiler combustion equipment is a fast-loading grate, which can be manufactured and installed in the factory and directly installed on the foundation after being transported to the site.With reasonable structure, compact, low steel consumption, so that the boiler performance, weight, structure and size compared with domestic boilers with the same capacity has obvious advantages

FAQ of biomass steam boiler

1.What is the size of furnace door and blower hopper?

Size of furnace door: 
Standard elliptical furnace door:300*800*1500
Blower hopper size:
2 tons conical hopper: 1400*800*1500
4 tons conical hopper: 2200*1400*1500

2.What is the combustion mode of coal/biomass fired boiler?

The combustion mode of coal/biomass fired boiler is layer combustion. Place the flue on the fixed or moved grate, to form an evenly fuel bed with a certain thickness, air comes from the bottom of grate, and combustion occurred on the fuel bed.

3.Material of boiler drum / steel plate / tube.

Boiler drum material: Q245R,carbon steel, executive standard: GB713-2008
Tube material: 20# seamless steel pipe, carbon steel, executive standard: GB3087-2008
Still kettle material: Q345R, alloy steel, executive standard: GB713-2008

4.What is the height of chimney?

The chimney is usually 30m, irrespective of the special circumstances.

5.What are the heat-resistance temperature of grate and furnace?

The heat resistance temperature of grate is related to the grate material, the highest temperature could be as high as 1100℃, and the lower temperature could be 700℃.
