Combustion of Biomass Fuel Steam Boiler Environmental Protection Resource Recycling
Introduction
Biomass boilers are very similar to conventional gas boilers that you will be familiar with, providing you with space heating and hot water for the entire home, but instead of using gas (or oil) to produce the heat, they combust sustainable source such as straw, rice bran, sawdust, bark, peanut shells, Stick, Miscanthus, Wood shavings, etc.
Performance advantages
1. The dense drainage cooling tube or membrane wall structure of radiation heat transfer segment, the convective heat transfer segment S-type multibackhaul heat exchanger tail arrangement of efficient fin economizer heat exchanger, high thermal efficiency.
2. Boiler quality insulation materials and special construction technology, less heat loss, the exhaust gas temperature is low, the high thermal efficiency of the boiler.
3. Heightening grate combustion chamber, the layout of the combustion of secondary air, fuel combustion evenly and high combustion efficiency.
4. Arch special design to grate, grate divided the warehouse into the wind, independent adjustment of air volume, fuel adaptability.
5. Heating surface arrangement is adequate and reasonable, the boiler temperature fast start.
Structural features
1. The boiler proper plumbing structure, double drum chain grate combustion.Drum along the boilers center arranged longitudinally up and down, the water wall tubes furnace radiation heating surface on the drum between the drum and the next bundle composed of the convection heating surface tail arrangement of economizer
2. Heightening grate combustion chamber, arranged lateral secondary wind; chain grate divided the warehouse into the wind, the air volume adjusted independently, grate stepless speed.
3. Feeding devices with independent intellectual property rights, lock feeding mechanism.
4. Radiative heat transfer surface, convective heat transfer surface using special anti-wear structure.
5. The boiler overall structure is compact, small footprint, a high degree of assembly, short installation period, less the cost of installation.
