GAS BOILERS VS. WASTE WOOD BOILERS - Semantic

2017-10-11 · operating waste wood boilers versus gas boilers which in turn increases cost of electricity. This does not account for the increase in cost for maintenance, motor failures, and other related maintenance issues. The natural gas boiler consists of only one motor, a combustion air fan. But, the waste wood boiler requires a multiple array of motors

Outdoor wood boilers- Wisconsin DNR

Recommendations for outdoor wood boiler operators. The state does not regulate outdoor wood boilers (OWBs). The suggestions below are based on information from a variety of sources including the Wisconsin Department of Health Services (DHS) and U.S. Environmental Protection Agency (EPA), and may help reduce pollution exposure complaints.

Comparison of emissions and toxicological properties

In medium-scale wood combustion, PM1 emission values from a grate fired wood combustion boiler (10 MW) without particulate filtration were the highest (264 mg MJ−1) but were substantially reduced down to 0.6 mg MJ−1 due to the usage of an electrostatic precipitator (ESP). The wood combustion particles were mainly formed of potassium salts.
