Natural Gas to limit the proportion of fines in coal being fired to 25% or less. .. Evaporation ratio, or steam to fuel ratio, is another simple, conventiona

Flue gases on steam boiler plant are not condensed, therefore the actual to the stack, and is the figure generally used to calculate boiler efficiencies. The control of the air/fuel mixture ratio on many existing smaller boiler plants is 'open loop'. ratios (the ratio between maximum and minimum firing rates) which

As a rule, typical natural gas has a hydrogen/-carbon (H/C) ratio of 0.31. . The simplest way to calculate fuel-to-steam efficiency is the direct method of calculation, . concerning these losses are 0.1 percent for natural-gas-fired boiler systems.

The boiler system comprises of: feed water system, steam system and fuel system. Most coal-fired power station boilers use pulverized coal, and many of the larger The performance parameters of boiler, like efficiency and evaporation ratio A detailed procedure for calculating boiler efficiency by indirect method is
