Steam Calculator: How To Calculate Steam Consumption | …

 · Proper utilization of steam helps in saving in the input cost of water and coal. Saving of each kg of steam is directly proportional to the saving of some percentage of water, coal and electricity. Calculation of steam consumption in a pipe during the start-up operation and normal continuous operation is possible, and will be discussed in detail below.
