Steam boiler fuel to steam efficiency Clayton Thermal

the cost of generation and the cost of consumption. If the plant has only one steam generator (boiler), uses a single fuel, and has a single steam pressure level, it is relatively easy to assign a cost to the steam. However, in most cases, there are multiple steam sources and multiple fuels. There are also multiple steam pressure levels with

Operating Costs Comparison of Different Fuel Boilers

Oct 25, 2018 · Here, we take a example to compare operating costs of different fuel boilers. Suppose: Heating 50tons 10℃ water into 42℃. 1kg water needs about 1 Kcal to rise 1℃. One kilogram of water needs 1 calorie to heat up. Because the feeding water of this calculation is 10℃, the temperature difference is 42℃-10℃ = 32℃ when it rises to 42
