4 tons biomass boiler is the most common boiler tonnage. ZOZEN can produce a variety of types of boilers with different tonnage, both from the boiler industry and from the boiler structure. Biomass, as a renewable energy source, has low sulfur content, low nitrogen content, and low NOx and SO2 content after combustion. The ash content in biomass is generally very small, so the soot content is very low after full combustion. At the same time, biomass combustion process has the characteristics of “zero” CO2 emission, the development and utilization of biomass energy has a broad prospect.

Biomass fuel is made of straw, wood, rice husk, peanut shell, corn cob, palm shell, sunflower shell and other processed block of environmental protection new energy. The diameter of biomass particles is generally 6 mm ~ 10 mm. The diameter of biomass particles is generally 6 mm ~ 8 mm, the length is 4 ~ 5 times of its diameter, the crushing rate is less than 1.5% ~ 2.0%, the dry base water content is less than 10% ~ 15%, the ash content is less than 1.5%, the S content and the Cl content are less than 0.07%, and the N content is less than 0.5%. As a clean fuel, ZOZEN has developed new furnaces that enable efficient and clean burning of biomass pellets.

The thermal efficiency of ZOZEN’s biomass boilers is generally more than 80%. With larger boilers and fuller combustion, the efficiency of the boilers is higher, up to 88%, which is 15% higher than the average efficiency level of coal-fired boilers. The ash produced by BMF combustion accounts for about 1.5% of the fuel. In order to facilitate ash discharge, a spiral slag discharge machine is arranged at the rear of the boiler to realize continuous ash removal. Dust collector is arranged in the flue at the end of the boiler to ensure that the smoke discharge meets the requirements of environmental protection.

DZL series biomass boiler adopts double cylinder longitudinal layout, combustion mode for chain grate suitable for burning biomass molded solid fuel. The water wall on both sides of the furnace adopts membrane water wall structure; Furnace front and rear wall water wall pipe extends down to the upper part of the grate to form a front and rear arch. After the furnace for burning chamber, convection tube bundle, tail economizer. The front wall is arranged with secondary air, controlled by the valve, which is put into use when burning biomass fuel to strengthen combustion, so that the fuel is fully burned out and the combustion efficiency is improved. Higher feed inlet is used to meet the demand of biomass fuel. If you need the 4 tons biomass boiler price, please contact us via email zhulin@ZOZEN.com or online chat.
