Cyclone-Furnace Boilers. B&W developed Cyclone furnace technology to burn coal grades that are not well-suited for pulverized coal combustion. The ash from these coals has a very low melting temperature. This molten ash would normally be deposited on all downstream heat transfer surfaces, causing severe slagging and fouling with resultant Get Price
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 and Get Price
