FIELD: heat power engineering. ^ SUBSTANCE: water boiler comprises overflow tank, pump, and heat exchangers provided with casing, mounted outside of the boiler housing, and connected with the steam-generating member through the pipeline. The steam-generating member is set in the furnace chamber. The inner space of the overflow tank is connected with the inner space of the casing of the heat-exchanging condenser through the pipeline. The sucking branch pipe of the pump is connected with the inner space of the overflow tank. The pressure branch pipe of the pump is connected with the steam-generating member. ^ EFFECT: enhanced efficiency. ^ 2 cl, 2 dwg |
