Chipped woody biomass with a defined particle size, produced by a machine with a blunt hammer action.
Hog fuel is any type of wood byproduct or waste that can be burned for fuel but can’t be categorized as chips, shavings, bark, or sawdust. It is the basic feedstock for biomass-fired power plants.
If burning hog fuel, commonly known as shred, you must have either a permit or exemption from the environmental or local authority to burn that material.
If your boiler does not have an appropriate feed system, hog or shred fuels can cause blockages and bridging . If it is not from clean, untreated wood, there maybe a chance of harmful chemical contaminants being released into the atmosphere or concentrating in the ash.
