Steam Boiler Questions and Answers - Steamesteem

Answer: Answer: There are different types of composite boilers. Normally one part of the boiler is heated by means of a fuel oil burner and the other part is heated by the exhaust gases from a diesel engine. Heating of one part of a boiler at the time often causes thermal stress that may lead to leakage.
