Similarly, PCFBC boilers achieve higher efficiencies due to smaller and more frequent bubbles, which results in better gas-solid contact. Combustion efficiency is affected by fuel type, bed temperature, gas velocity, and excess air levels. Combustion efficiency increases with fuel volatile matter content and bed temperature.Get Price
Hot water boilers can be used for most types of heating systems. Hot air furnaces are only suitable for ducted hot air systems. For solid-fuel-fired forced hot air heating systems, a boiler is usually a better choice than a hot air pellet furnace. Manual ignition hot-air pellet furnaces waste fuel by maintaining combustion all the time.Get Price
