Steam Cost = ($8.00/MMBtu/106 Btu/MMBtu) x 1,000 lbs x 1,006 (Btu/lb)/0.857 = $9.39/1,000 lbs. Effective Cost of Steam The effective cost of steam depends on the path it follows from the boiler to the point of use. Take a systems approach and consider the entire boiler island, including effect of blowdown, parasitic steam consumption and deaeration.Learn More
The amount of fuel requried will be different for different types of fuel. It depends on the energy density of the fuel. The specific heat of water is 4186J/kg and latent heat of vaporization is 2260kJ/kg. Let's assume we are loading the boiler wiLearn More
the boiler, steam loop, and controls. Non-fuel O&M costs range . from 0.6 to 1.0 ¢/kWh for the three steam turbines shown in Table 3. Similar to capital costs, there are economies of scale, and the O&M costs decline on a per kWh basis as the steam turbine capacity increases. The O&M costsLearn More
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 multipleLearn More
Jan 01, 2014 · It is advisable to check with the boiler manufacturer that the steam sections of the boiler (super-heaters and re-heaters) can support the weight of water. This can be a problem for the re-heater pipework because it is designed for much lower pressures and therefore lower stresses, and it is best to use dehumidified air.Learn More

Jan 31, 2013 · Total Steam Cost ($/MMBtu) = Fuel Cost ($/MMBtu) x 130%. Calculating Unloaded Steam Costs. For boilers, we've found this boiler steam cost calculator (Internet Explorer compatible only). Alternatively, unloaded steam costs are calculated in the manner specified below: SC = (a F * (H g _ h f) ) / (1,000 • ηB) Where: SC = steam cost, …Learn More
A boiler fired with natural gas costing $8.00/MMBtu produces 450-pounds-per- square-inch-gauge (psig) saturated steam and is supplied with 230°F feedwater. Using values from the tables, calculate the fuel cost of producing steam.Learn More
