In the current world energy shortage, serious environmental pollution, biomass as a renewable energy. The biomass has low sulfur content and low nitrogen content, and the content of NOx and SO2 is very low after combustion. The ash content in biomass is also generally very small, so the soot content is very low after full combustion. At the same time, the biomass combustion process has the characteristics of zero CO2 emissions, and the development and utilization of biomass energy has broad prospects. 20 Tonnes biomass fired boiler design thermal efficiency can reach 82.68%, the use of energy conservation and environmental protection.

Biomass steam boiler is a kind of biomass boiler using rice husk, wheat straw, straw, bark and other corner waste as fuel, used to produce and operate. It can be widely used in power generation in thermal power plants, central heating, winter heating for urban residents, process hot water and domestic hot water supply. This series steam boiler has high calorific value and good combustion. Using biomass molding fuel, compared with the original calorific value of 50-1000 kcal, calorific value between 3200 kcal -5280 kcal. Combustion temperature up to 1060℃, can completely replace coal, is a high volatile solid fuel, combustion rate of more than 95%.

The 20 Tonnes biomass fired boiler is actually determined by its overall cost. The 20 ton biomass steam boiler belongs to the category of chain grate boiler, but can burn pure biomass fuel, can also burn a mixture of biomass fuel and coal. This series of steam boilers have large ratio and long burning time. The density of straw can reach 0.9-1.4g/cm3 after crushing, pressurizing and dense forming. The volume of the molded product is only 1/30 of the original straw. Greatly prolong the burning time, is the original same weight straw 10-15 times, easy to store and transport.

Biomass fired steam boiler use green, environmental protection, low carbon. Biomass briquette fuel has high calorific value, high density, ash content of 5% and sulfur content of less than 5. The residue after combustion is high quality potash. Normal combustion without soot and black smoke emissions, carbon dioxide is almost zero emissions. Greatly lower than the emission standard, to meet the requirements of environmental protection. The boiler has large heat transfer coefficient, good heat transfer effect, low heat loss, good air tightness, no deformation of furnace wall, no ash leakage. In terms of structural design, it has a larger furnace space compared with traditional boilers and a very reasonable secondary air layout, which is conducive to the full combustion of biomass fuel combustion.

The 20 Tonnes biomass fired boiler is not only easy to slag after burning out fuel, but also can fully reduce the formation of NOx, SOx and other harmful gases. Moreover, electricity saving can reach 30%, biomass fuel saving can reach 5%, and the annual operating time is more than 8000 hours. DZL biomass boiler adopts light small scale chain grate which can feed evenly, control conveniently and combustion is more stable. The design of this type of boiler is optimized to solve the problem of easy coking of the boiler, and the thermal efficiency is significantly improved and the fuel cost is saved.
