Rated Evaporation Capacity: 20t/h

Rated Steam Temperature: 194℃

Installation Method: quick installation

Applicable Fuel: a variety of fuels

Boiler Introduction: The designed fuel is biomass briquette fuel. There is an economizer at the end of the boiler. The flue gas enters the tail flue through the furnace, the combustion chamber, the convection tube bundle, and the economizer, and is discharged into the atmosphere through the dust collector, induced draft fan, and chimney.

 

20t/h Biomass Fired Boiler Product Description

Biomass fired boiler is a type of boiler, and the boiler that uses biomass energy as fuel is called biomass boiler. The steam boiler adopts combustion equipment that is most suitable for biomass fuel combustion. In terms of structural design, the furnace space is larger than that of traditional boilers, and at the same time, a very reasonable secondary air is arranged. It is conducive to the full combustion of a large amount of volatile matter precipitated instantaneously when the biomass fuel is burned. The boiler can be equipped with oil (gas) ignition burner to realize ignition automation. The boiler’s feeding, combustion, slag removal, water feeding and ignition can all be automatically controlled, and the operation is very convenient. The boiler is equipped with an automatic dust removal device, which can remove the dust on the heating surface of the boiler in time, and ensure the efficient and stable operation of the boiler. An economizer is arranged at the rear of the boiler, and an air preheater can also be arranged according to user needs.

Compared with traditional boilers, the boiler has higher efficiency and lower exhaust gas temperature. Using high-efficiency insulation materials, this boiler products surface temperature is low, and the heat dissipation loss can be neglected. It is produced in strict accordance with Chinese national norms and standards, and all pressure parts are made of high-quality boiler steel. Each boiler must undergo rigorous inspection and testing before leaving the factory, including hydraulic test and x-ray inspection. There are manholes, inspection doors, fire viewing holes, etc., which are very convenient for maintenance.

4. Non-Standard Customization
   Private customization, support special size customization with drawings and samples.
5. Stable Operation
   Operation under slight negative pressure, no backfire and off-fire phenomenon occurs.

Overview of Biomass Fired Boiler Design

Water cooling system: including front water wall tube, side water wall, convection tube bundle, upper and lower drums, downcomer and header.

Drum: The outer diameter of the upper drum is 940mm, the thickness is 20mm, and the length is 8610mm (not counting the end caps), the inner diameter of the lower drum is 940mm, the thickness is 20, and the length is 4670mm (not counting the end caps). The materials are all used Q245R. The lower drum rests on the chassis through two steam drum supports, and the rear one is a movable support. The center distance of the upper and lower drums is 2250m, and the upper drum is supported on the welded water-cooled wall and the convection tube bundle. Inside the upper drum, there is a steam-water separator, a gas equalizing orifice plate, and a surface drain device, and the lower drum is equipped with a drain device.
