Steam Generation Suggested Actions

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

Questions about improper header efficiency, cracking top

Feb 06, 2022 · If you ever find an old coal fired CI boiler and open the fire door you will see a threaded plug in the bottom on the crown sheet of the boiler probably 3-4 sections from the front of the boiler. The "fuseable plugs" were just a 1/2" brass pipe plug they would drill a hole in it and fill the hole with solder or something like solder that would

16. A steam boiler generating 7.1 kg/s of 4.137 Mpa, 426.7 0-C steam is continuously blown at the rate of 0.31 kg/sec. Feed water enters the economizer at 149.9 0C. The furnace burns 0.75 kg coal/sec of 30,470.6 KJ/kg higher heating value. Calculate the overall thermal efficiency of steam boiler. Answer C A. 76.34% B. 84.23% C. 82.78% D. 88.34%
