Description

Domestic gas lands stove
Technical field
The utility model relates to the combustion type heating equipment, specifically is that a kind of domestic gas lands stove.
Background technology
Along with popularizing of natural gas, coal bed gas, the combustion type heating equipment obtains application more and more widely with its low emission, advantage easy to use.Existing combustion type heating equipment mainly is divided into wall hanging stove, gas and hot water heating boiler etc.Wherein, the wall hanging stove must be switched on when using, and caused its cost higher and be unfavorable for penetration and promotion; And the gas and hot water heating boiler is limit owing to self structure; There is little, the problem inhomogeneous, that the thermal efficiency is low of being heated of heating surface area, cause energy waste easily, and the gas and hot water heating boiler in use; Be prone to residual unburned combustion gas in the body of heater, cause potential safety hazard easily.For these reasons, be necessary to invent a kind of brand-new combustion type heating equipment, with solve existing combustion type heating equipment heating surface area little, be heated inhomogeneous, the thermal efficiency is low, cost is high and the problem of poor stability.
Summary of the invention
The utility model for solve existing combustion type heating equipment heating surface area little, be heated inhomogeneous, the thermal efficiency is low, cost is high and the problem of poor stability, provides a kind of domestic gas to land stove.
The utility model is to adopt following technical scheme to realize: domestic gas lands stove, comprises furnace shell, is located at the body of heater in the furnace shell, the combustion chamber of being located at the burner hearth in the body of heater and being located at the burner hearth below; The body of heater sidepiece has delivery port and water return outlet; Burner is installed in the combustion chamber; Burner top is equipped with combustion grate, and the burner bottom has fuel gas inlet; Be provided with water jacket between furnace body outer wall and the inboard wall of furnace body; The layer pipe heat exchanger of being made up of the heat exchanger tube array is installed in the burner hearth, and the heat exchanger tube array comprises that several horizontally are fixed in the burner hearth and the heat exchanger tube that is parallel to each other; Each heat exchanger tube all is communicated with water jacket; Roof of the furnace has exhaust outlet; The body of heater upper end is fixed with waste heat and absorbs water tank, and waste heat absorbs in the water tank waste heat recovery pipe is installed; Waste heat recovery Guan Yiduan is communicated with burner hearth through exhaust outlet, and the other end is communicated with outward with furnace shell.
During work, delivery port, water return outlet are communicated with heat supply pipeline, fuel gas inlet is communicated with gas pipeline.Through water return outlet water filling, water filling in waste heat absorbs water tank simultaneously in water jacket and layer pipe heat exchanger.Combustion gas gets into burner through fuel gas inlet, igniting operation then.The concrete course of work is following: combustion gas is in the burner internal combustion; And above combustion grate, produce flame; Directly heat the heat exchanger array in the layer pipe heat exchanger in the gap that flame passes between each heat exchanger tube, because water jacket is communicated with heat exchanger tube, the water in the water jacket also obtains heating.In heating process; Flame institute heat content major part is absorbed by the water in heat exchanger tube and the water jacket; The contained waste heat of flame then gets into the waste heat recovery pipe through burner hearth, exhaust outlet successively, and the water in the waste heat absorption water tank is heated, and realizes that thus the secondary of waste heat absorbs.Meanwhile, the waste gas of fuel gas buring generation is discharged outside the furnace shell through the waste heat recovery pipe.Based on said process; Compare with existing combustion type heating equipment, the described domestic gas of the utility model lands stove and adopts layer pipe heat exchanger of being made up of the heat exchanger array as heat exchange structure, has increased the heating surface area in the heating process; And make be heated more even; Absorb water tank and waste heat recovery pipe owing to set up waste heat simultaneously, the waste heat that makes burning produce is able to secondary and absorbs, and has therefore improved the thermal efficiency.In addition; The described domestic gas of the utility model lands stove and in use need not energising, and its cost is lower compared to the wall hanging stove, and simultaneously its heat exchange structure in use can not be detained any unburned combustion gas; Thoroughly stop potential safety hazard thus, improved security.
Further, the body of heater bottom is fixed with base, has the air vent that is communicated with the combustion chamber on the base.Base makes that laying of body of heater is convenient, and air vent then is convenient to when fuel gas buring, feed fresh air to the combustion chamber, thereby plays combustion-supporting effect.
The utility model is through adopting brand-new heat exchange structure, efficiently solve existing combustion type heating equipment heating surface area little, be heated inhomogeneous, the thermal efficiency is low, cost is high and the problem of poor stability, be fit to family's gas-heating and use.
