Understand Why Furnace Size Varies for Gas, Oil and …

20/7/2009 · The coal fired boiler furnace size is generally higher in volume by 20 to 35 %, depending on coal types, when compared to an oil fired boiler. The factors that increase the furnace size are many. The reactivity of coal is much lower than oil and hence need more residence time. Even though the adiabatic flame temperature is higher than oil, the

INCREASING THE ENERGY EFFICIENCY OF BOILER AND …

Typical Energy Balance of a Boiler/Heater (before improvements) Energy in fuel enters the boiler (energy input 100 percent). From the boiler, 4 percent of heat loss is through radiation and convection, 18 percent is in flue gasses and 3 percent is in blowdown. Energy in heating medium (e.g. steam) exits the boiler.

Direct co-firing is a simple approach and the most common and least expensive method of co-firing biomass with coal in a boiler, usually a PC boiler. As shown in Fig. 4.1, in direct co-firing technology biomass is fed directly into the furnace after either being milled together with the base fuel ( Fig. 4.12A ) or being milled separately ( Fig. 4.12B ) The fuel mixture is then burned in the
