1. Working principle of wood chip fired biomass boiler

1.1 Working Principle

Wood chip biomass fired boilers operate by burning biomass fuels like wood chips to produce heat energy. The process involves feeding the fuel into the combustion chamber, where it is ignited and burned under controlled conditions. The generated heat is transferred to water or other media through heat exchangers, creating high-temperature steam or hot water for heating and industrial use. Emissions are managed through flue gas treatment systems to meet environmental standards. Advanced automation ensures efficient fuel feeding, ignition, and combustion, enhancing safety and performance.
