Overview of Biomass Steam Boiler

A biomass steam boiler is an industrial heating system that burns organic materials—such as wood chips, pellets, agricultural waste, or bagasse—to generate high-pressure steam for industrial processing, power generation, or district heating. These systems provide a renewable, eco-friendly alternative to fossil fuels, reducing carbon emissions by using sustainable, carbon-neutral fuel sources.

Product advantages

Environmental benefits
Biomass boilers are fueled by renewable wood and plant waste. Their use can greatly cut the need for fossil fuels and the harm to the environment. Burning releases as much carbon dioxide as plants absorb. So, a biomass boiler cuts emissions, which fights climate change and slows warming.

Economic Advantages
Biomass fuels are usually more stable and cheaper than fossil fuels. Using biomass boilers can cut energy costs, boost energy efficiency, and save money for users. Biomass boilers can enjoy these economic advantages.

Energy efficiency
Biomass boilers have a big advantage over conventional heating systems. They are better at converting and using thermal energy. Biomass boilers are usually very efficient. They can make full use of the energy in biomass fuels. They turn the fuel into heat and increase energy efficiency.

Reducing Dioxin Generation
When biomass is burned at high temperatures above 800°C, biomass steam boilers exhibit excellent environmental performance and are able to greatly reduce the production of harmful pollutants such as dioxins. This feature makes the biomass steam boiler has a clear advantage in environmental protection, in line with the requirements of strict environmental standards.

Common types

Fixed grate biomass steam boiler

This is a traditional biomass steam boiler, This type of boiler is suitable for users who need a small amount of steam, steam production is generally 1-6 T / H.The biggest advantage of this biomass steam boiler is that it can use waste wood and wood production trimmings, branches, etc.

Chain grate biomass steam boiler

This biomass steam boiler typically produces 2-35T of steam per hour.This is a kind of biomass steam boiler that adopts chain grate as the fuel transfer device, which can realise the automatic feeding of fuel, greatly saving the manpower cost of boiler use and further reducing the comprehensive operation cost of enterprises.

Material used

The pressure parts of the boiler body, such as the drum, furnace liner, and pipes, are mainly made of boiler carbon steel, such as Q245R and Q345R.

Stove grate system (key components)

Stove plate: Made of heat-resistant cast iron (such as chromium cast iron) or heat-resistant steel to withstand high temperatures and wear.

Stove rack and chain: Made of high-quality carbon steel or alloy steel.

Furnace wall and insulation: The furnace section is constructed with heavy-duty furnace walls (refractory bricks) or lightweight blocks, and is covered with insulation materials (aluminum silicate fibers) and color steel plates on the outside.

Auxiliary system: Carbon steel, stainless steel or anti-corrosion materials are selected according to the characteristics of the medium for the air supply fan, induced draft fan, dust removal and desulfurization tower, etc.

Application

Process steam supply

Provides heat source for the production process of the factory, such as steaming, drying, dyeing, and chemical reactions.

District heating

By using heat exchange stations, the heat generated by boilers is converted into hot water to provide heating for the building complex.

Power generation

In small thermal power plants or enterprise owned power stations, steam is produced to drive steam turbines for power generation (usually in cogeneration mode).
