WATER HEATING SPACE FOR A BOILER WHICH HEATS WATER USING HEATED AIR CAPABLE OF HEAT-EXCHANGING AIR AND WATER

摘要

PURPOSE: A water heating space for a boiler which heats water using heated air is provided to extend stagnation time of water and air by discharging the water and air in a zigzag form. CONSTITUTION: A water heating space(13) for a boiler which heats water using heated air is composed of blowers, a heater, and a pipe line(11'). The blowers blow external air. The heater has an air inflow hole, an electric heater, and an ejecting port. Air flows into the air inflow hole. The electric heater heats the air. The ejecting port discharges the heated air. The pipe line comprises an inflow hole(10') and a discharge hole(11). Water flows into the inflow hole to heat the water by the air. The water flows in a zigzag form.
