The Essential Guide to Industrial Hot Water Boilers

High Temperature Hot Water Boilers (HTHW) According to ASME, a High Temperature Hot Water Boiler is an ASME Section I Power Boiler and includes any boiler with a maximum temperature exceeding 250°F and/or maximum pressures exceeding 160 PSIG. In application, HTHW systems refer to those designs where the temperatures exceed 350°F.

Methods of Estimating Steam Consumption | Spirax Sarco

Mean steam consumption. The mean steam consumption of a flow type application like a process heat exchanger or heating calorifier can be determined from Equation 2.6.6, as shown in Equation 2.6.7. But as the mean heat transfer is, itself, calculated from the mass flow, the specific heat, and the temperature rise, it is easier to use Equation 2.6.7.

Nov 03, 2006 · What is the fuel consumption of a 10,000#/hr steam boiler using diesel as fuel (VHI = 130,000 BTU/gal) with a feedwater temperature of 154 °F? FC = [ SP * ( hs – hw ) / ( BE * VHI ) ] FC = [ SP * ( hs – hw ) / ( BE * VHI ) ] FC = [ 10000 * (1190 – 122) / ( 0.8 * 130000) ] FC = 102.7 gal Where, FC = Fuel consumption SP = steam produced

Why hot water and not steam? — Heating Help: The Wall

Feb 14, 2012 · The difference in fuel consumption to produce steam, versus hot water is astronomical! To heat one pound of 60 degree water to 180 degree water is 120 btu's, and that's a nominal temp for baseboard heat. To heat one pound of 212 degree water to produce 212 degree steam, changing states from liquid to a gas, requires 941 btu's!!!

Steam Boiler vs Hot Water Boiler - ATI of NY

Oct 12, 2016 · When it comes to the steam boiler vs hot water boiler, the operating principles are more or less the same. Both steam boilers and hot water boilers (also called hydronic boilers) involve the heating of water and creation of steam through the burning of fuel. The heated water is transmitted through boiler tubes, while the steam created is circulated throughout the facility with the assistance
