Steam out Water in Q5–2 Boiler q1–2 = w1–2 (h2 – h1) + (kE2 – kE1) + PE2 – pE1) – q1–2 = h2 – h1 Heat is lost by the system to the cooling water q1–2 = h1 – h2 2. receives 3600Kg of steam per hour. The steam enters the turbine at a velocity of 80m/sec, an elevation of 10m and specific enthalpy of 3276KJ/kg
Read MoreME Board Problem Local coal with higher heating value of 5,500 kCal/kg is burned in a pulverized coal fired boiler with 25% excess air at the rate of 25.9 M.T. per hour when the steam generated is 220 M.T. per hour. This boiler is served by 2 forced-draft fans of equal capacity delivering the air at 305 mm of water to the furnace.
