Fire coal water heater

Abstract

The invention relates to a fire coal water heater which is characterized in that a front sealed water tank and a rear sealed water tank are respectively arranged at the front side and the rear side below the middle part of an interlayer water tank body. Two water tanks are communicated via a plurality of fire bar tubes; one end of an overflow tube arranged below the fire bar tubes is communicated with the front water tank, and the other end thereof passes through the rear water tank to be communicated with the bottom of the interlayer water tank via a water conduit; the rear water tank is provided with a discharging tube; and the discharging tube and the water conduit are respectively provided with a binding head; the whole body composed of the rear water tank, the front water tank and a plurality of fire bar tubes can move out of or be matched into the furnace body; a hearth top is in the horizontal state; the hearth top is internally provided with a plurality of heat-absorbing tubes; the interlayer water tank on the upper half part of the rear side of the box body is the heat-absorbing box three surfaces of which are sealed and the top of which is opened; and a water inlet is arranged above a water-stop sheet behind the box body. The fire coal water heater has the advantages of saving energy to causing heat efficiency to reach 96%, having strong adaptability to be used by fire coal or firewood, and being convenient for cleaning and maintenance to be worth popularizing and using.

Description

Technical field: [0001] The invention relates to a water heater, in particular to a coal-fired water heater which uses coal or firewood as fuel for supplying hot water for bathrooms. Background technique: [0002] At present, coal-fired water heaters in the prior art, such as patent number: ZL200720039630.5, coal-fired water heaters, have also taken a series of measures in order to save coal, and are used to collect the lost heat, but there are the following problems during use There are two problems: first, the structure is complex, such as making the furnace into a trapezoidal manufacturing process, which is difficult and costly; second, the grate pipe and heat-absorbing pipe are not easy to descale and clean; High temperature, energy saving is not good enough. Contents of the invention [0003] The purpose of the present invention is to provide a coal-fired water heater that overcomes the above-mentioned shortcomings, has a simple structure, low cost, more energy-savin...
