The presence of unburned fuel in a power plant’s ash indicates an inefficient combustion process, as some of the energy in the fuel is being wasted. Unburned fuel also poses a risk to safety; if ...

Coal combustion in blast furnaces underpins modern ironmaking by partially replacing metallurgical coke with injected coal. Pulverised coal is carried by hot blast air through tuyeres into the raceway ...

Forced-air heat is generated at a central furnace and is then distributed and delivered to the conditioned space via a duct system. A properly designed heating system will generate quiet, filtered, ...

As HVACR technicians, assessing whether the furnace we’re servicing is working efficiently is critical to understanding the overall health of the HVAC system — and to the success of our service call.

Boiler slagging and fouling, and the resulting frequent operation of sootblowers, are some of the major operations and maintenance factors that can negatively affect power plant reliability and ...

Waste incineration is one of many societal applications of combustion. As illustrated in Figure 3-1, the typical waste-incineration facility includes the following operations: Waste storage and feed ...
