The project's aim is to reduce the emission of CO2 by increasing the efficiency of two existing steam boilers fuelled by hard coal and heavy fuel oil. The boilers efficiency will increase by applying the Therma Chem FS12 fireside treatment technology to the combustion process, thus preventing slugging and fouling on combustion chamber walls, boiler tubes, air-pre-heater surfaces and economizers.

2021/11/10 · If your boiler's circulating pump is hot to the touch, this could be due to a blocked rotor from worn-out bearings, or possibly a buildup of dirt. However, it's important to note that while it's common for the pump to get warm, or even hot, it should never become dangerously hot.

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.

In some circumstances, steam demand increases are so disruptive to boiler operation that boiler life as well as steam quality suffers. In some cases, the external water level indicator shows the water level as satisfactory, yet the actual level of the water/steam mixture in the boiler may be filling the steam space and water may be literally pouring into the steam lines by steam demand syphoning.
