Water flows through tubes that are surrounded by a cavity of hot gases. Water tube boilers are capable of producing 10,000 to 1,000,000 pounds of steam per hour.

Understanding Steam & Boiler Heating Systems | HomeAdvisor

Boiler Systems Operation. In steam heating systems, a boiler furnace heats water by means of a gas or oil-fired burner and turns it into steam. The steam travels through pipes to radiators or convectors, which give off heat and warm the room. As the steam cools, it condenses back into water, and returns to the boiler to be heated again.
