But the question remains: are these wood fired steam boilers any useful? Let’s find out all the answers regarding wood boilers in this guide.

What Is A Wood-Fired Steam Generator?

Small Wood Fired Steam Generator

Wood-fired steam generator is a system that converts boiling water into steam. Generally, it is used for industrial applications ranging from small to large-scale projects and productions.

A steam generator consists of a combustion chamber. That is where the fuel burns; in this case, wood burns. Therefore, this is a wood pellet steam boiler. However, this system can also work on natural gas, petroleum fuel, coal, or biomass.

You will need wood planks or pellets to fire this steam generator. Typically, the generator has a movable grate that allows you to feed wood easily. However, the construction can vary depending on the boiler’s size and brand.

Is Wood Fired Steam Generator Suitable for Industrial Applications?

Yes, wood-fired steam generators are suitable for industrial applications. They come in different sizes. The small wood-fired steam boiler is considered the standard for industrial and commercial usage. However, many industries operate on a large scale. Hence, they will need a more powerful steam generator.

Furthermore, these systems are not limited to producing steam. They can also produce hot water, depending on their capabilities. So, what is a steam generator used for? Here are some common industrial applications of this system:

  • Sterilization
  • Distillation
  • Disinfection
  • Production

Modern industrial wood boilers offer better capabilities. They are not limited to a single energy source. Instead, these generators can run on multiple fuel types. For instance, an advanced wood fired boiler may also work with biomass or coal.

Components of Fired Steam Generator

A wood fired steam generator is useful for industrial applications, primarily because of its construction. Here are its main components and their working:

  • Furnace

A furnace is present in almost every industrial generator responsible for combustion. A wood fired boiler’s furnace has a storage unit for wood. The furnace conducts the primary process: burning the wood and producing steam.

  • Pellet Boiler Storage Tank

The storage tank is where the product resides for future use. After the chamber releases the product, this component stores steam or hot water in a wood-fired steam generator. That is why this generator is a cost-effective option. It can streamline industrial operations and save money by saving reserves for the future.

  • Cyclone Dust Collector

When there’s wood, there’s dust. Considering that aspect, this boiler has an automatic dust collector. Generally, it has a dust bag to collect all the debris and unwanted particles. So you can keep the operation area clear. Also, it helps prevent dust allergies and other health problems.

  • Flue Gas Extractor

A flue gas exists in all boilers, which is a by-product of the process. According to the conservation of mass, no mass can be created or destroyed, it can only be converted from one form to another. In this case, burning the wood does not mean destroying the mass. Instead, it converts into ashes and vapors, also called flue gases.

They are emitted using different channels, like pipes or tubes. Generally, they are located near the furnace. This way, the gasses don’t have to travel far from their production area. The flue gas extractor in a wood fired boiler transports the flue gasses from the system. It requires setting a maximum temperature, maintaining furnaces and their operations.

  • Forced Draft Fan

Another important component is the forced draft fan in keeping the environment clean. It creates a mechanical air pressure that is much-needed when dealing with wood pellets or chips. Manufacturing and many other industrial processes consider this component an integral one!

  • Water Treatment

One of the primary reasons for the woodchip boiler’s durability is its supportive components. A good example would be water treatment. It removes potentially harmful substances from the processes that can otherwise damage the boiler. These substances can lead to corrosion or foaming, reducing the generator’s lifespan and affecting wood steam boiler efficiency.

  • Chimney

The chimney is essential to any boiler, regardless of its energy source. It releases the toxic gasses exhausted from the boiler’s operations. The wood fired steam generator also has a chimney attached to its furnace. It handles the ventilation, keeping the work environment healthy.

  • Grate Reducer

Grate reducers are relatively newer components in a boiler. Their fundamental purpose is to assist with burning fuel. In this case, this component helps the furnace to burn wood by passing the required air for the process. 

  • Ash Conveyor

Ash is another consideration when working with wood or coal. It can be physically harmful to the workers. That is why this steam boiler has an ash conveyor. This component transfers the ash produced during the generator’s operations to another unit. Generally, these boilers use a tube to move ash from one part to another.

  • Automated Control System

A modern wood fired steam generator requires minimal human interference. All you need is to set the basic requirements for the processes. Then, the wood fired hot water boiler works with ACS (automated control system). It calculates and takes minimal input and offers optimal output. Also, it ensures that all the components work collaboratively and smoothly. As a result, the system handles tasks more efficiently, requiring fewer human resources.

  • Additional Components

Also known as auxiliaries, these essential components are responsible for efficient processing. Auxiliaries may include dust collectors and self-cleaners to keep the generator organized and ready for more usage.

Additionally, you have an FD Fan or ID Fan to collect and throw air toward the generator. Valves can help you adjust the heating levels according to your requirements. Lastly, slag removers, boiler economizers, and many other tools can keep the processes intact while maximizing efficiency. All of these should come as auxiliaries with your wood boiler system.
