  3. Fire-tube boilers are generally limited in size to approximately 25,000 lb/hr (11,340 kg/hr) and 250 PSIG (1.7 MPa) saturated steam. A typical coal-fired utility boiler might produce 3 million lb/hr (1.36 million kg/hr) of superheated steam at 2400PSIG (16.5 MPa). A typical nonelectric utility industrial boiler might produce 400,000 lb/hr (181,000 kg/hr) of steam at 900 PSIG (6.2 MPa). Industrial boilers are commonly referred to as Co-Generation or combined heat and power (CHP) applications. Dept. of Electronics & Instrumentation, Narayana Engineering College, Nellore.

  7. Heat Balance Balancing total energy entering a boiler against the energy that leaves the boiler in different forms 12.7 % Heat loss due to dry flue gas BOILER 8.1 % Heat loss due to steam in fuel gas 1.7 % 100.0 % Heat loss due to moisture in fuel 0.3 % Fuel Heat loss due to moisture in air 2.4 % Heat loss due to unburnts in residue 1.0 % Heat loss due to radiation & other unaccounted loss 73.8 % 73.8 % Heat in Steam Dept. of Electronics & Instrumentation, Narayana Engineering College, Nellore.
