A central burner with a stable flame is in the main heat cavity; the collecting heater pipe is a spiral finned tube and is arranged between the main heat cavity and the secondary heat cavity; the central burner with a stable flame is in the shape of a hollow cylinder. The utility model can take gas, fuel oil and coal as the fuel, has the advantages of being high heat efficient, energy-saving, environment-protective, and high benefit. The utility model can be used for hot water supplying and heat adoption.

Description

Helical fin tubular type central authorities combustion furnace

One, technical field

The utility model relates to the central combustion furnace of a kind of helical fin tubular type, can adopt combustion gas, fuel oil, fire coal to be fuel, belongs to family expenses hot-water supply, heating stove.

Two, background technology

At present domestic existing be hot-water supply, the heating stove of fuel with combustion gas, fuel oil, coal, ubiquitous problem is that the thermal efficiency is low, the fuel consumption height, the cost height, one side has been wasted effective resource, has strengthened user's cost of use; On the other hand, because a large amount of dischargings of waste gas, waste residue cause environmental pollution.Trace it to its cause, in fact due to the unreasonable structure of its body of heater of genus.With the hot-water supply that generally adopts, the coal furnace that heating is used is an example, the employing water tank type that has, the employing helix tube that has, its main heat transfer mode is convection current, so the thermal efficiency is not high, energy consumption is higher, does not obviously meet the requirement of energy-saving and environmental protection, so change its structure, it has been the task of top priority that release energy-saving and environmental protection product makes it to enter huge numbers of families.

Three, utility model content

The purpose of this utility model is at above problem, by the improvement to the stove internal structure, provides a kind of helical fin tubular type central authorities combustion furnace that can solve thermal efficiency height, energy savings, environmental benefit great question;

The technical scheme that adopts that achieves the above object is: helical fin tubular type central authorities combustion furnace, and it mainly comprises furnace shell, heat-insulation layer, furnace chamber and thermal-collecting tube, furnace chamber is made of main thermal cavity and the hot chamber of secondary, and a central stable flame burner is arranged in the main thermal cavity; Thermal-collecting tube is a spiral fin coil, be between the hot chamber of main thermal cavity and secondary, also has a flow plug therebetween, between spiral fin coil and the hot chamber of secondary, central stable flame burner is a hollow cylindrical, and is all porose on it, water inlet and delivery port are connected on helical fin thermal-collecting tube and the furnace shell, but the fin spirality on it also can be a straight plate shape, the two optional one; Flow plug is a round tank that has a plurality of strip openings on it;

The utility model compared with prior art, has following usefulness: adopt central burning structure, discharge behind combustion waste process main thermal cavity and the hot chamber of secondary, improved the distribution situation of ignition temperature, and the unburning material in the combustion waste is fully burnt, reduce waste discharge; Thermal-collecting tube adopts spiral fin coil, thereby has changed this pipe flow regime on every side, and this pipe places between main thermal cavity and the hot chamber of secondary, thereby has strengthened the heat exchange of convection current, conduction and even radiation; Adopt stable flame combusting device, burning can be fully burned, in sum, adopt technology provided by the utility model, can reach the benefit of thermal efficiency height, energy-saving and environmental protection.
