The first step, which has several components, is to calculate the cost of generating steam from the boiler(s): 1. Fuel (CF) 2. Raw water supply (CW) 3. Boiler feed water treatment—including clarification, softening, demineralization (CBFW) 4. Feedwater pumping power (CP) 5.
Why Is My Boiler Letting Out Steam? A NJ Tech Explains
If your boiler pressure levels are over 30 psi (pounds per square inch), your pressure relief valve is letting out steam as a safety measure. You see, your pressure relief valve is designed to prevent your boiler from building up too much pressure and will automatically discharge hot water/steam when pressure levels hit a dangerous level of 30

Steam Generation Suggested Actions - Energy.gov
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. Steam Cost = ($8.00/MMBtu/106 Btu/MMBtu) x 1,000 lb x 1,006 (Btu/lb)/0.857 = $9.39/1,000 lb
