Steam, produced in the boiler at 10 bar g, is to be used as the heating agent. If the 'From and At' rating of the boiler plant is 10 tonne/h, determine the flowrate of steam required to heat the deaerator. Before any calculations can be made to estimate the size of the deaerator, it is important to know the maximum likely feedwater requirement.
Energy in heating medium (e.g. steam) exits the boiler. Energy output (boiler thermal efficiency) is between 75 and 77 percent. Recent examples: A chemical plant is saving $500,000 per year by checking for, and replacing, all leaking steam traps. A plywood plant reduced its steam load by 2700 kg/h (6000 lb./h) by upgrading its piping insulation
