Wood pellet steam generator have become increasingly popular in the industrial sector. They require a cheaper energy source to work. Moreover, their higher efficiency and low maintenance make them cost-effective. A wood pellet steam generator is one of the most popular options in this category.
But what is a wood pellet steam generator? More importantly, is it worth buying? Let’s answer all these questions in this detailed guide. We will also discuss 5 reasons to choose a wood pellet steam boiler. So, let’s get started!
How does a wood pellet steam generator work?
Every boiler requires an energy source to work. In this case, wood is the fuel to burn. A pellet isn’t the only form of wood this generator runs on; you can also put chips, corn cobs, and any type of wood leftovers. It also runs on bamboo sticks and rice husks.
So, how does it work? Here’s the basic framework of a wood chip generator:
- The operator inputs wood via the pellet belt feeder.
- The wood goes through to the chain grate surface.
- The boiler ignites the wood and provides energy to the boiler drum.
- Lastly, the heat is transferred to the water in the boiler to produce hot water or steam.
The smartly designed components of this generator handle these complex operations. For instance, the pellet belt feeder automatically fetches the input and passes it forward for further processing. Additional auxiliaries can assist with secondary tasks, like discarding the impurities via the slag remover.
Then, you also have some components that maintain the generator’s durability, like fans. Lastly, the tubes and pipelines help obtain input and pass the output without affecting the boiler’s processes.
Types of Wood Pellet Steam Generators
This boiler itself is a type of wood fired steam generator. Plus, there are many ways to divide a boiler into multiple types. These categorizations may be based on a generator’s capacity, advanced framework, or output product.
The following types of wood pellet steam generators are based on their output: Let’s look at them one by one:
1. Output: Hot Water
A pellet generator that produces hot water output works like a wood fired hot water boiler. It burns the input pellets in its chamber. The furnace and chamber are adjacent to each other. That means the boiler can also store the incoming wood pellets.
The furnace burns the wood and produces hot water by passing the heat. Generally, the operator has to set the temperature for the process. The input range can be anywhere from 0.4 to 1.25 MPa.
2. Output Thermal Oil
The output thermal oil boiler is the most common one. It absorbs heat to produce hot oil. But how does it work? Generally, these pellet generators have conduction oils with circulating pumps. You can set the temperature according to your requirements and use your wood pellets as fuel.
These boilers offer several benefits, like stable processing, that you might not find in most other generators. Furthermore, this pellet generator can recycle liquid oil to save fuel for reheating.
3. Output: Wood Pellet Steam Generator
Lastly, we have the most common type used for commercial and industrial applications. This pellet boiler produces steam by burning wood in its furnace. It allows for the conversion of harmful byproducts and wastes into reusable fuel.
Industrial wood fired steam boilers come in various sizes. Most of them are suitable for both indoor and outdoor installations. Their temperatures range from 35F to 350F, while the pressure is between 0.4 MPa and 3.82 MPa. Another thing to note is that they can handle a significant output range, with several models producing over 50 tons per hour.
A wood fired generator that produces steam is suitable for multiple applications, including industrial production, manufacturing, and home heating.
5 Key Reasons to Buy a Pellet Steam Boiler
Let’s look at some reasons why an industrialist should opt for a wood pellet steam boiler:
1. Smart Design
The design of a wood pellet steam generator makes it highly efficient. It has all the essential and secondary components to streamline its operations. Furthermore, it also takes into account the environmental factor. Most of these boilers have auto-dust removers. They can help keep the work area safe, minimizing pollution and guaranteeing the safety of workers.
2. Significantly Cheaper
Let’s say you have bought a gas- or fuel-powered boiler. That will be ten times more expensive than a wood generator in the long run. Why is that? These fuels are comparatively more expensive than wood pellets.
The best part is that wood generators accept all forms of wood. Hence, you are not limited to pellets only. Instead, you can use chips or leftovers. Ultimately, it makes industrial operations relatively cheaper than other boilers.
3. Higher Heating Capacity
The wood fired boiler can handle higher temperatures. They allow operators to set the desired output, making them suitable for industries of all scales. An average wood generator can support temperatures of up to 350 °F. The best part is that you can easily adjust these levels during operations. Combine this factor with the high-pressure tolerance, and you have one of the most capable boilers!
4. Less Care is required.
A wood boiler is self-caring. It has all the essential components, like ID and secondary fans. Furthermore, parts like a slag remover can ensure no impure particles get mixed up in the generator’s processes. This way, the boiler can sustain itself, prolonging its lifespan and maintaining its efficiency.
5. Energy Efficiency and Compatibility
Many wood pellet boilers are compatible with secondary energy sources. For instance, a wood chip generator can also take biomass as input. That can make the system more versatile and usable in different scenarios.
Additionally, these boilers are highly efficient. Their efficiency rate is above 80% due to their supportive design and auxiliaries.
5 Things to Consider When Buying a Pellet Steam Generator
Are you looking for a wood pellet steam generator for sale? Here are the four main factors to consider:
Modern steam generators are automated, regardless of their energy source. This automation eliminates the need for an operator. Also, many other costs can be discarded with an automatic boiler. It can handle heavy lifting tasks like loading, adjusting, and discharging.
Another benefit associated with automation is safety. Since an operator has to do minimal work to ensure a boiler works, there are fewer chances of accidents.
But that’s not all. Automation also brings ease of use for a boiler operator. What if the operator has no experience working with a wood pellet generator? Then, a system that requires minimal human input can help. It can make their job easier while providing a higher efficiency rate.
An average pellet steam generator can work at more than 80% efficiency. However, this rate can vary depending on various factors. That includes:
- Boiler’s design
- Secondary components or auxiliaries
- Degree of automation
- Heating capacity
Remember that efficiency is a byproduct of a well-rounded boiler. You can expect an 84% to 86% efficiency rate if all its core components and aspects are effective.
3. Components and Auxiliaries
Auxiliaries can heavily impact the efficiency of a pellet steam generator. You can expect a dirty workplace if components like a dirt bag are absent. Similarly, the absence of fans can slow down operations, resulting in lower efficiency.
Like auxiliaries, durable components are also vital. The system must have reliable and strengthened steel plates, tubes, and drums. Otherwise, the boiler might not be able to handle higher temperatures. As a result, it will suffer from wear and tear, causing the boiler to go out before its expected lifespan.
To test a manufacturer’s reliability, check their warranty period. This simple factor can help you save money and invest in the right place. You have many trusted companies, like Yongxing Boiler Group. We offer a 5-year warranty period with boiler maintenance, customer support, repairs, and spare parts.
