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 …Learn More

A time delay relay is a way to squeeze the most heat out of your system without running the boiler. When the thermostat clicks on, the relay causes the boiler to circulate hot water through the system without turning on the boiler. After a set time, the boiler will fire up. A time delay relay costs about $100 and can cut your fuel …Learn More
The combustion system modifications and boiler performance impacts are several important aspects to be considered. The combustion system modifications include the firing configuration, emission requirements, fuel supply, and controls. The key boiler performance impacts include furnace exit gas temperature, radiant superheater absorption,Learn More
Each boiler has a boiler master, which is an A/M/Bias station that handles the firing rate for that boiler. In AUTO, the boiler master receives the plant master output, biases it, and sends that % to the fuel and air flow controllers. In MANUAL, the boiler master output is adjusted by the operator.Learn More

Jan 01, 1982 · Sectional boilers designed principally for solid-fuel firing are also fired by oil fuels and gas. The majority are for hot-water service, but some have been used for the generation of low-pressure steam. The sizes range up to several thousand kW. Such boilers have been gas-fired by forced-draught package burners and also by natural-draught burners.Learn More
Suspension firing or pulverized-fuel combustion uses pulverized fuel, which is transported pneumatically and blown into the boiler together with the primary air.
