A Calculation Method for CO2 Emission in Utility Boilers Based on BP Neural Network and Carbon Balance …

2017/5/1 · Under the BP network prediction model, the average difference of carbon content of burning coal was about 1.80%, while that of CO2 emission were 3.92% and 0.96%. Compared with emission factor method and capacity standard method, the method in this paper is more suitable to count the CO2 emission of utility boilers. © 2016 The Authors.

EMISSIONS OF SULFUR TRIOXIDE FROM COAL-FIRED POWER …

2006/6/21 · Emissions of sulfur trioxide (SO3) are a key component of plume opacity and acid deposition. Consequently, these emissions need to be low enough not to cause opacity violations and acid deposition. Generally, a small fraction of sulfur in coal is converted to SO3 in coal-fired combustion devices such as electric utility boilers.

Natural Gas Fired Boilers

The 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
