Mar 17, 2015 · 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.

Both the EX and LX models of Miura water tube boilers have a fuel-to-steam efficiency rating of 85 percent, compared to the average fire tube boiler that only offers 83 percent fuel-to-steam efficiency. There may seem like a small difference, but that 2 percent difference in efficiency creates fuel cost savings between 10 and 40 percent.

Since the air-fuel stoichiometric ratio is 14.4 pounds of air per pound of fuel, the boiler's burner would need 20 gallons x 7.95 lb/gal for No. 6 fuel oil, or 2,289 pounds of air to burn the oil. This would in turn yield a total flow of 2,628.1 lb/hr of steam.

Boiler cycling also effects emissions. See Boiler Combustion. An important consideration is the boiler efficiency at each operating range. Old boilers have a simple low and high fire setting. The air-fuel ratio is set by fixed position dampers and linkages. The ability to control boilers with simple mechanical linkages over a wide range can be

Combustion Air: Fuel/ Air Ratio. Burner air-fuel ratio plays a critical role in achieving maximum efficiency out of fuel-fired process heating systems such as furnaces, ovens, heaters, and boilers. If the amount of air supplied is less than required, the burner will run "rich" i.e. not all fuel will burn inside the furnace.

A boiler turndown ratio refers to the ratio between a boiler's highest fire setting (maximum output) and lowest fire setting (minimum output). Turndown ratios vary depending on the boiler. For example, if your boiler has a 3:1 turndown ratio, that means that at its lowest fire setting you will be operating at 33% of the boiler's full capacity.
