A power plant incorporates a boiler that produces steam at the rate of \( 93 \mathrm{~kg} / \mathrm{s} \). The steam condition at boiler outlet is \( 100 \mathrm{bar}, 500^{\circ} \mathrm{C} \) and the condenser pressure is \( 0.1 \mathrm{bar} \). The boiler efficiency is \( 90 \% \). The boiler consumes fuel oil of calorific value \( 42.0 \mathrm{MJ} / \mathrm{kg} \). The feedwater temperature at boiler inlet is \( 160^{\circ} \mathrm{C} \). The steam generator has risers in the furnace wall \( 40 \mathrm{~m} \) high and unheated downcomers. The quality at the top of the riser is \( 8 \% \) and a minimum exit velocity of mixture leaving the riser and entering the drum is required to be \( 2 \mathrm{~m} / \mathrm{s} \). The risers have \( 60 \mathrm{~mm} \) o.d. and \( 3 \mathrm{~mm} \) wall thickness. Neglecting any pressure drop and heat loss, as well as the pump work, estimate: a) the capacity of the power plant, b) the fuel burning rate, c) the evaporation factor, d) the pressure head available for natural circulation, the circulation ratio, e) the number of risers required, and f) the heat absorption rate per unit projected area of the rise.....

O#2 A power plant incorporates a boiler that produces steam at the rate of 93kg/s. The steam condition at boiler outlet is 100bar,500C and the condenser pressure is 0.1bar. The boiler efficiency is 90%. The boiler consumes fuel oil of calorific value 42.0MJ/kg. The feedwater temperature at boiler inlet is 160C. The steam generator has risers in the furnace wall 40m high and unheated downcomers. The quality at the top of the riser is 8% and a minimum exit velocity of mixture leaving the riser and entering the drum is required to be 2m/s. The risers have 60mm o.d. and 3mm wall thickness. Neglecting any pressure drop and heat loss, as well as the pump work, estimate: a) the capacity of the power plant, b) the fuel burning rate, c) the evaporation factor, d) the pressure head available for natural circulation, the circulation ratio, e) the number of risers required, and f) the heat absorption rate per unit projected area of the riser
