This series boiler uses the general combustion technique. The biomass fuel is feed by workers manually. After burning in the fire grate, the exhaust gas pass through the horizontal water tube, and the small carbon block and dust in the exhaust gas fall on the fire grate and re-burn. Then the exhaust gas is released to the air through the chimney.
1. Compact structure, easy to install, small footprint, small investment.
2. Multi-pass and multi-return, the dust can be removed naturally without ID fan, save energy.
3. Horizontal pipes increase the radiation heating area.
4. High thermal efficiency ,exhaust gas passes through the forced convection tube bundle.
5. Small capacity boiler, fit for the small industrial.
