Stack Economizers should be considered as an efficiency measure when large amounts of make-up water are used (ie: not all condensate is returned to the boiler or large amounts of live steam are used in the process so there is no condensate to return) or there is a simultaneous need for large quantities of hot water for some other use.

According to the ASME Energy Balance Method of calculating industrial boiler efficiency, you should account for convection losses, radiation losses, and stack losses. However, you should dig a little deeper to understand the factors that directly affect these important readings, which ultimately affect industrial boiler efficiency.

Typical boiler efficiencies are 80 percent for natural gas-fired boilers, 75 percent for biomass-fired boilers, and 83 percent for coal-fired boilers. The calculation of effective electric efficiency is the CHP net electric output divided by the additional fuel the CHP system consumes over and above what would have been used by a boiler to

Boiler Horsepower What is the boiler horsepower of a boiler generating 21,500 lbs of steam per hour at 155 psi? The factor of evaporation is 1.08. BHP = (LB/HR*fe)/34.5 BHP Boiler Horsepower BHP = (LB/HR*fe)/34.5 Lb/Hr Pounds per Hour BHP = 21500 * 1.08 / 34.5 Fe Factor of Evaporation BHP = 673 Cycle

The entire system (furnace/boiler, ducting, and piping) must be evaluated to determine the true efficiency of the system. Combustion efficiency is a valuable part of the system evaluation, but it is only one part of the evaluation process and cannot be used as the sole reason or justification for keeping or replacing existing equipment.

25% of the boilers'evaporation rate, the efficiency gain can be more. To figure this, you begin by calculating the flow to the economizer. Use 34.5 pounds of steam per boiler horsepower and a gallon of water weighs 8.3 pounds. A 200 HP boiler will then develop approximately 6900#/hr and at 25% makeup is 1726#/hr divided by 8.3#/
