The second step is to calculate the cost of steam at lower pressure levels. This is not easy, as the cost depends upon the path that the steam follows from the point of generation to the point of use. Low-pressure steam that is produced through a pressure letdown station, usually a pressure-reducing. Here is the equation to calculate an unloaded steam cost: = Steam cost, unloaded = Fuel cost in $/MMBtu = Enthalpy of steam, in Btu/lb. = Enthalpy of boiler feedwater in Btu/lb. = True boiler efficiency (ASME PTC 4.1) o Percentage = Steam cost is measured in 1,000 lbs. per hou This brief details how to calculate the true cost of steam, which is important for monitoring and managing energy use in a plant, evaluating proposed design changes to the generation or distribution infrastructure and the process itself, and for continuing to identify competitive advantages through steam system and plant efficiency improvements Online calculator to quickly determine Steam Unit Cost.

Our tools enable companies to develop comprehensive and reliable inventories of their GHG emissions. Calculating emissions is a multi-step process. An accurate and useful inventory can only be developed after careful attention to quality control issues and to the activity data required. Only then should emissions be estimated. The GHG Protocol's Corporate Standard provide Turbine Steam Consumption Calculations. The usual way of representing the steam consumption of a turbine is the willans line, for example.... Often, a willans line for a specific turbine is not available, and one only has has incomplete information about an installed steam turbine; namely the rated power and (perhaps a guesstimate) the isentropic efficency or specific steam consumption at full.
