Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

2015-10-15·Verify boiler water level. Check the furnace and flue passes for fuel accumulation. Any unburned fuel should be thoroughly removed. Check flame detection devices. Purge furnace for at least 3-5 minutes to fully clear gas passages. If burner fails to ignite within five seconds, shut off fuel supply and re-purge furnace.

Boiler Types and Classifications. There are two general types of boilers: ''fire-tube'' and ''water-tube''. Boilers are classified as "high-pressure" or "low-pressure" and "steam boiler" or "hot water boiler."Boilers that operate higher than 15 psig are called "high-pressure" boilers.

Get A QuoteBoilers designed to generate steam for both industrial and power generation application use fuels like coal, oil and gas. The variation between oil and gas fired boiler furnace size is to a smaller extent only. Furnace being the heart of boiler has to be sized correctly for the fuel being fired. This requires knowing why the sizes vary with the fuels.

A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.
