Pellet boiler - Wikipedia

Pellet boiler. A pellet boiler is a heating system that burns wood pellets. Pellet boilers are used in central heating systems for heat requirements (heating load) from 3.9 kW ( kilowatt) to 1 MW (megawatt) or more. Pellet central heating systems are used in single family homes, and in larger residential, commercial, or institutional applications.

Residential-Scale Biomass Boiler Emissions and Efficiency

Detailed particulate and gaseous emission characterizations were conducted on six commercially available residential-scale wood pellet boilers. The objective of the study was to define emission factors for these six different appliances burning wood pellets, grass pellets, and a blend of grass pellets and corn as fuels under low and high loads. Continuous monitoring of criteria pollutants
