Embodiment 1

[0031] Such as figure 1 , 2 , 3, 4, 5, and 6, the hearth in the body of the furnace is made up of fuel combustion chamber 13, volatile matter combustion chamber 14 and volatile matter annular combustion chamber 23, and the stove mouth 28 is arranged on the axis of the cone 29, and the cone 29 can move up and down, and the upper surface of the cone 29 is the bottom surface of the pot stove mouth 27, and the pot stove mouth 27 is on the axis of the upper surface 26 of the body of heater, and is provided with for placing the blower; It is composed of two layers of concentric vertically arranged inner heat-absorbing pipes 6 and outer heat-absorbing pipes 7 on the periphery of the cone, and the two ends of the inner heat-absorbing pipe 6 communicate with the inner annular upper water jacket 1 and the inner annular lower water jacket 12 respectively; The two ends of the outer heat-absorbing pipe 7 communicate with the outer annular upper water jacket 3 and the outer annular lower w...

Embodiment 2

[0043] Such as figure 2 , 6 , 7, the difference from Embodiment 1 is that the fire grate 34 and the combustion speed control door 33 are removed and replaced with a combustion nozzle 43, and cobblestones 44 are placed in the secondary combustion chamber 14 to the annular combustion chamber. All the other structures remain unchanged, so that gas or liquid fuel can be used for heating or cooking and boiling water.

Abstract

The invention relates to a kind of boiler, especially a kind of squatting double-duty boiler which is used to cook, boil water and supply heating, the double-duty boiler consists of furnace shaft, firebox in the furnace shaft and decalescence equipment, firebox consists of fuel blast chamber, volatile blast chamber and volatile annular combustor, decalescence equipment is made up of two floors of heat pipes which encircles outside of the firebox, heat pipes connects with each other through annular jackets above and below the furnace shaft, the outlet is set up on the top annular jacket, the inlet is set up on the lower annular jacket, annular thermal convection switch room is between two floors of heat pipes, annular floss hole is between annular thermal convection switch room and firebox, the lower ends of annular thermal convection switch room connects with funnel outside the furnace shaft; The invention has a high thermal efficiency, discharges few injurants, adopts many different kinds of fuel to heat, releases contaminant simply and has no danger of blast, it has a long life and a simple structure, moreover, it is convenient to be used.

Description

technical field [0001] The invention relates to a squatting boiler, in particular to a squatting dual-purpose boiler capable of cooking, boiling water and providing heating. Background technique [0002] At present, the development trend of winter heating for rural residents is to use the independent heating device as the unit of the family (that is, soil heating), which requires the boiler to meet the needs of the family for cooking and boiling water on the premise of heating. There are many unavoidable problems in traditional domestic dual-purpose boilers: 1. Low thermal efficiency, generally 30%-40%; 2. Huge emissions of harmful gases such as energetic gases, greenhouse gases, and black smoke; 3. Soot and dust Particles increase with the increase of exhaust gas temperature; 4. Since raw water is directly used as the exchange medium of the heating system, the problem of mineral condensation (scale) in the water is serious, and the thermal efficiency of the boiler differs g...
