2018/4/24 · Wood-fired grate boilers had 6-21-fold PM1 and 2-23-fold total suspended particle (TSP) concns. upstream of the particle filters when compared to those of HFO-fired boilers. However, the use of single field electrostatic precipitators (ESP) in wood-fired grate boilers decreased particle emissions to same level or even lower as in HFO combustion.

Get priceThe boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas. When firing natural gas, other losses such as dry gas loss, moisture in fuel and

Boiler Input = 33.5 MMBtu/hr (Based on 80% Efficiency) Annual Hours of Operation = 8760 hours/year (24 hours/day x 365 days/year) Substituting this data into the previous equation yields the annual NOx emissions for this specific boiler, which is 19.1 tpy. NEW SOURCE PERFORMANCE STANDARDS.
Get priceThe flame temperature can be decreased to 2000 F. and lower, as opposed to about 3000 F. for conventional fire tube boilers. Therefore NO x emission is lower than in the standard burner/boiler unit due to the lower flame temperature and lower excess air.
