Purchasing Energy-Efficient Large Commercial Boilers

NOx reductions from uncontrolled boilers at a cost effectiveness of $1700-5000/ton. However due to limited full scale experience, the cost estimates for SNCR and SCR have a high degree of uncertainty. Combustion modification controls for oil/gas fired utility boilers have been used since the early 1970s primarily in California.

Environmental performance assessment of utility boiler

Jul 15, 2016 · Boilers with higher EYR and lower ELR have the better ESI. The biomass boiler system has an ESI of 270, which is the highest of the cases studied in this paper. The fossil fuel boiler systems have a relatively low ESI. The ESI of oil fired boiler (8.9) is slightly higher than the natural gas fired boiler (8.1).

Boiler - an overview | ScienceDirect Topics

II.C.1.a Firetube boiler. The firetube boiler can be described in simple terms as a water-filled cylinder with tubes running through it which provide the escape path for the combustion gases or flue gas. As the flue gas passes through the tubes, the hot gases heat the tubes, which then heat the water to produce steam. The firetube boiler is primarily used in industrial applications.

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
