Best Wood Chip Boiler - Top-Grade Energy-Efficient Biomass Heating System
Basic Introduction And Value Of DZL-type Biomass Boiler
Yongxing Boiler designed and built the DZL-type biomass boiler. This is a single drum, longitudinally-arranged chain grate boiler that is primarily fired using biomass pellets. The DZL-type biomass boiler is a next generation high-efficiency and low-energy consumption boiler product.
Biomass fuels are a superior quality renewable energy source. They are readily available and can be used in place of coal to provide heating for industrial applications. Replacing coal with biomass fuels will allow companies to significantly reduce their operating expenses and generate substantial cost savings.
In addition, using agricultural and forest waste as biomass fuels will create additional revenue streams for farmers and contribute to the economic development of rural areas. As such, the use of biomass fuels provides both financial and social benefits.
Structural Design And Combustion Principle Of DZL-type Biomass Boiler
To achieve complete combustion of the biomass pellets, the DZL biomass boiler employs a horizontal three-pass water/fire tube arrangement and high-efficiency enhanced combustion technologies. Due to the large size of the furnace and combustion chamber, all residual ash from the burned pellets will settle out prior to exiting the boiler.
At the exit of the flue gas stream from the boiler, there is a coarse dust separation turning chamber. This chamber will remove some of the larger particles (primary removal) from the flue gas before it leaves the boiler, thereby reducing the amount of particulate matter in the flue gas. All other emissions produced by the DZL biomass boiler are well within the allowable limits set forth by national environmental regulations.
The DZL biomass boiler has a quick warm-up period, an overall high thermal efficiency, and adequate heating surface area.
Performance Characteristics
- By utilizing threaded smoke tubes for heat exchange, the thermal efficiency of the system will increase while reducing the overall amount of energy required.
- The use of a membrane water wall allows for an increase in the heat exchange coefficient and effectiveness, as well as a decrease in heat loss.
- Threaded smoke tubes are placed inside the boiler shell, which provides minimal air leakage and therefore reduces heat losses from the flue gas.
- Submerged arc automatic welding is employed to ensure that all welding performed on the boiler is of the highest quality.
- A dust collector is installed within the rear flue to provide a clean environment by meeting environmental standards for both smoke and dust emissions.
- Due to its high level of automation, this system has the ability to automatically adjust water levels; interlock protection when low water levels occur; and provide an alarm when there are either high or low water levels.
- An inverted “α” flame has been created through the design of the arch that allows for the support of burning low-grade coal and offers a wide range of coal types that can be burned.
- With complete control and monitoring instrumentation, this system will operate safely and reliably.
- Two-sided flue ducts allow for smooth passage of flue gas into the front smoke box. The uniform heating across the tube plate eliminates cracks caused by thermal stresses.
- A new small-scale grate slice and exclusive safety ring have been incorporated into this design to provide a more consistent operation of the grate and increase the efficiency of burning fuel.

What Is A Wood Chip Boiler?
Yongxing wood chip steam boilers have a unique furnace design that can support the combustion of wood chips. As wood is easily available at low prices in many regions, our highly-skilled engineers have decided to design a wood chip burner boiler.
The burning of wood chips produces heat for converting water into steam. At Yongxing, first, we have a concern to double the profits of your industry with our high wood chip boiler efficiency. Second, environmental protection.
Therefore, we have utilized advanced technology to burn wood as fuel. Compared to oil-fired boilers, our wood pellet fired steam boilers have almost zero carbon emission rates. How so? The biomass fuel that includes plant and animal waste, rice husks, wood chips, etc., emits a small amount of CO2.
When burned, they emit the carbon that was absorbed in their life cycle. In simple words, the carbon absorbed from the environment is released back. So, there is no extra emission.
In addition, our best wood chip boilers have a low fuel consumption rate. Different advanced designs are incorporated in order to reduce fuel consumption. First is the economizer.
The economizer absorbs the heat of exhaust gases before it exits the environment. The heat absorbed is then transferred to the cold feedwater. Thus, the warm feedwater will need less energy to convert into steam. And, the best wood chip boiler will consume less fuel.
Secondly, the hot exhaust gases may damage the exhaust pipelines of your wood chip biomass boiler. Therefore, the economizer reduces the temperature so that it lasts longer.
We have different types of biomass boilers; they have different thermal efficiency, feeding system, fuel consumption rates, automation, etc.
We have large and small wood fired steam boilers for residential and industrial use. In this guide, we will have an in-depth look into all of them.

How Does A Wood Chip Boiler Works?
Our best wood chip boiler working principle is very similar to other boilers except for the fuel.
Firstly, the wood pellets for biomass boiler burns in the furnace and produce heat. The water tubes inside the furnace, in which the water is flowing, absorb the heat and flows in their specific passes.
After fully absorbing heat, the water converts to steam. Then, it passes through the superheater to convert into saturated dry steam.
The waste flue gases pass through the economizer to warm the cold feedwater. Afterward, the ash-removed exhaust gas goes out of the system through a chimney.
Finally, the ash removed from the exhaust gases drops down to the ash collector from where it can be easily removed.
