Design of SHL 10-1.25 / 250 - A boiler

Abstract: This design SHL10-1.25 / 250-A type boiler belongs to the low pressure small boiler, uses the double drum horizontal type boiler. Fuel from the coal bucket down to the grate, turn the grate, the coal transported to the furnace burning. Water circulation route: first from the lower part of the drum tube convection tube down to the lower drum, after each drop tube into the tank, and then from the water wall tube rise, into the upper drum. The upper and lower drums are arranged in close contact with the convective tube bundle, and in accordance with the direction of the flue gas flow using the folding way; in the boiler tail shaft is arranged cast iron economizer and air preheater. The main contents are: fuel combustion calculation, furnace design calculation, design of slag pipe design, design of superheater, boiler tube bundle design calculation, economizer design calculation, air preheater design calculation. These calculations include a variety of small computational items. The fuel combustion calculations include air balance calculations, theoretical flue gas and theoretical air calculations, calculation of flue gas characteristics in each flue, flue enthalpy and flue enthalpy, Heat balance calculation and calculation of fuel flue gas consumption, calculation of furnace structure, calculation of heat transfer area, calculation of slag pipe structure, calculation of heat capacity, calculation of superheater structure, calculation of heat capacity, calculation of boiler tube bundle structure, calculation of heat capacity, economizer structure calculation, heat Calculation, air preheater structure calculation, thermodynamic calculation.The design includes task description, calculation instructions, boiler body diagram, air preheater part drawing, economizer part drawing.

Key words: chain furnace boiler ; structure design ; thermodynamic calculation
