Abstract

The invention discloses a firing method with naturally balances the air circulation while the water gas heater is working, and its device. The method features that it cools the air channel of the combusting device by water cooling so the inner cavity of the air channel would not auto-ignites under the high temperature burning; it acquires the multi-layer lapping longitudinal combusting of the combusting devices. The fire nozzles of the combusting devices can be arranged and burning longitudinally. The advantages of the invention lies on following aspects: 1. with out reducing rated water production, the length of heating tube is lengthened by several times compared to it of existing techniques, relatively lengthening the heating period and reducing the gas consumption at the same rate, due to which the indoor oxygen consumption is naturally balanced same as the gas oven which is more safe; 2 the combusting device is capable of being made with aluminum fine casting technique in consequence of the adopting of water cooling technique lowering the cost and varying the shape, the apparent can be made into various shapes suiting the combusting devices, by longitudinally and lapping installing several combusting devices the thickness of the combusting device is reduced from 10 centimeter to 3 centimeter and the thickness of the water heater shell is reduced by half or more.

Description

The combustion method of circulation of air natural equilibrium and device when making gas water heater working

The present invention relates to a kind of combustion method and device thereof of gas heater, circulation of air realizes the combustion method and the device thereof of natural equilibrium in the time of especially making gas water heater working.

Existing gas heater is to constitute burner side by side and place coil heat exchanger and aqueous vapor linkage on the burner to form by a plurality of fire rows are parallel.Because the heat pipe length of heat exchanger is difficult to increase, reach the specified productive rate of hot water of same temperature in the unit interval, then must strengthen gas consumption, to improve the intensity of fire of burner, promptly caused the indoor oxygen supply and demand natural equilibrium, particularly winter especially can not cause indoor a large amount of anoxic when door and window closes thus.

In order to overcome a large amount of oxygen consumptions that short heat pipe need large-scale combustion amount that existing gas heater exists is caused, make the problem that room air can not natural equilibrium, the method that the present invention adopts is: change the burning of burner horizontal into vertically folded the burning, be that burner not only has the fire hole that is arranged in parallel, and increased the fire hole of vertical arrangement again, make burner before, after, a left side, right, last five surfaces lower surface of fuel gas inlet (have except), all can constitute combustion front, thus, the heat pipe of heat exchanger can prolong its length of being heated around vertical growth of burner four sides (or 360 ° of faces of cylinder) fire hole, to reach the purpose that prolongs the current heated time.After the current heated time prolonged, gas consumption just can correspondingly reduce in the unit interval.Promptly under the basic premise that guarantees the specified productive rate of hot water, adopt the vertically folded burning of burner and prolong heat pipe to reach the mode that prolongs the current heated time, make interior gas consumption of unit interval be limited in the air natural balanced state, keep becoming a reality as the intensity of a fire of gas-cooker.

Can only horizontal burn in order to overcome existing burner, the heat pipe length of heater and current heated time all are difficult to the problem of prolongation, the method that the present invention adopts is: the air flue of burner is inserted in the water heater water route any one section with the mode of connecting, make air flue can in time use water cooling, the unlikely barbecue because of high temperature makes combustion gas spontaneous combustion in air flue, like this, burner just can level off puts burning for vertically folding burning, four three-dimensional faces can have fire hole spray combustion, make to prolong heater heat pipe length and prolong the current heated time to become a reality.

Beneficial effect of the present invention, the short heat pipe large-scale combustion amount that is to change prior art is the little quantity combusted of long heat pipe, can make the intensity of a fire of the gas consumption maintenance of unit interval as gas-cooker, not to the room air pollution that exceeds standard, realize the circulation of air natural equilibrium, can keep specified hot water productive rate again.
