In the locomotive boiler, the saturated steam is very often passed into a superheater, back through the larger flues at the top of the boiler, to dry the steam and heat it to superheated steam. The superheated steam is directed to the steam engine's cylinders or very rarely to a turbine to produce mechanical work.
The SM Fire Tube Boilers are our high efficiency direct fired two pass dry back boilers. The burner fires down the center of the fire tube, which is located either on the left or right side of the boiler. The flame travels down the fire tube and enters the inversion chamber.
The dry back design refers to the use of refractory at the back of the boiler in the inversion chamber. The SM Fire Tube Boilers is specifically designed to minimize the thermal stress on the boiler not only at high pressures, but at low pressures as well.
Three pass boilers: A three pass design provides three opportunities for heat transfer. The stack temperature of 3 pass will be lower than that of 2 pass boiler, of the same design and operating pressure. Efficiency is more than two pass boiler. Each pass in boiler should be designed with cross sectional area to achieve optimal flue gas velocity, which in turn maximizes heat transfer while also minimizing performance robbing sooth build up within the tubes. No.
