<p>A boiler includes a water tank (9), a smoke exhaust pipe (6), a combustion chamber (1) and a fuel supply device. A furnace (5) is provided in the water tank (9), and one end of the smoke exhaust pipe (6) is connected with the flue gas outlet of the furnace (5), while the other end passes through the furnace (5). The part of the smoke exhaust pipe (6) in the furnace (5) is spiral. The combustion chamber (1) is set at the bottom of the furnace (5) and communicated with the furnace (5), and the fuel supply device is connected with the fuel inlet of the combustion chamber (1). The invention improves the heat energy utilization of high temperature flue gas, and solves the problem of water pipe blockage caused by scale in the current boiler.</p> |
