Biomass Fired Steam Boiler

As a renewable new energy source, biomass energy has been widely used in various industries and fields. Biomass as a fuel also has its irreplaceable role, such as low price, wide sources, and high calorific value. Corresponding biomass-fired steam boilers are becoming more and more popular among users.

Currently, biomass fired steam boilers that are widely used mainly use these as fuel: wood, rice husk, palm husk, coconut husk, biomass pellets, bagasse, etc.

The classification of biomass fired steam boilers.

but currently, there are two or three more common boiler models. 

One is a fixed grate biomass boiler, which is suitable for large block fuels such as wood, coconut shells, sugar bagasse, etc. One is a chain grate boiler, suitable for rice husks, biomass pellets, etc. There is also a circulating fluidized bed boiler. There are reciprocating grate boilers, circulating fluidized bed boilers, and so on.

biomass fired steam boiler structure:

In addition to the difference in boiler grate.

biomass fired steam boilers are divided into two types: 

water-fire tube boilers and water-tube boilers.

Water fire tube boiler

There is only one drum, so it is also called a single drum boiler. The boiler consists of a grate, header, convection tube bundle, riser and down tube, drum, smoke tube, and smokebox. The boiler frame is generally made of refractory cement and refractory bricks. Insulation materials and iron sheeting are added to the outside.

Water-tube boiler

There are two drums, the upper drum is long and the lower drum is short. Also known as a double drum boiler, the boiler is composed of a grate, header, convection tube bundle, water wall (membrane water wall), drum, smokebox, etc. The boiler frame is generally made of refractory cement and refractory bricks. Insulation materials and iron sheeting are added to the outside.

The two types of biomass fired steam boilers have their own advantages.

Advantages of biomass fired steam boiler:

1. Various and convenient ways to obtain fuel. There will be no shutdown due to fuel shortages.

2. Fuel prices are relatively low.

3. The boiler structure is mature, safe, and stable.

4. The chain grate biomass fired steam boiler has a higher degree of automation.

Disadvantages of biomass fired steam boilers.

1. The content of nitrogen sulfide in biomass is relatively high. If it is an area with high environmental protection requirements, it is best to perform desulfurization and denitrification treatment. Or equipped with a wet dust collector.

2. The dust produced by biomass combustion is far more than other solid fuels. To prevent the dust collector from clogging, it is necessary to clean the dust collector frequently.

3. The thermal efficiency of biomass fired steam boilers is relatively lower than that of coal-fired boilers.

Supporting biomass fired steam boiler:

Boiler. Electric control system, water treatment system, water circulation system, energy-saving device, dust removal system, air supply system, conveying system.

Including boiler body, water treatment, water pump, electric control box, economizer, dust collector, slag remover, blower, induced draft fan, pipeline, instrument valve, etc. According to your needs, let your engineer design the boiler system for you.
