Abstract

The utility model discloses a flame directly burns heating pipe, the heat absorption is efficient, the make full use of energy, the steam production is big, the little cross tube boiler of the cigarette environmental pollution that discharges, this boiler is on the basis of current various model boilers, does not change the overall structure of boiler, only has set up the heating pipe of certain quantity in furnace, the heating pipe is by preceding arch pipe, back arch pipe and cross pipe are constituteed, the one end and the pot angle of heating pipe link to each other, the other end links to each other with lower header.

Description

The cross pipe boiler

The utility model relates to a kind of boiler.

At present, the domestic boiler that adopts, its cold wall pipe is the both sides at body of heater, only absorb heat by radiation, heat absorption efficiency is very low, has caused a lot of thermal loss, exhaust gas temperature is generally more than 200 ℃, the thermal efficiency has only about 65%, has wasted a lot of energy, particularly environment is had very big pollution.

The purpose of this utility model is to provide a kind of flame directly to burn heating tube, and heat transfer coefficient is bigger about 2.5 times than general boiler, and the thermal efficiency improves more than 10%, the cross pipe boiler of exhaust gas temperature below 120 ℃.

The purpose of this utility model is to realize like this, this cross pipe boiler is by cross pipe, preceding arch tube, the heating tube that rear arched tube is formed, drum, lower collecting box, cold wall pipe is formed, it does not have to change the overall structure of existing boiler, just the cross pipe intersection with some is installed in burner hearth inside, flame in the burner hearth directly burns heating tube like this, wherein be installed in the cross pipe in the burner hearth, preceding arch tube, rear arched tube one end links to each other with drum, the other end links to each other with lower collecting box, the middle Bu Wei Wei of cross pipe has one to bend, and angle of bend is that the first half and the horizontal tilt angle of cross pipe is 30 °, and heating tube adopts φ 51 * 3.5 pipes, pipe is apart from being 110～120mm, and the angle of inclination of rear arched tube is 30 °.

The utility model is arranged on the inside of burner hearth owing to adopted above-mentioned structure with the heating tube of some, so have following characteristics:

One, owing to cancelled front and back cement arch and aerofoil profile refractory brick, maintenance cost and installation fee have been saved;

Two, arch tube angle in front and back changes 30 degree into by 18 degree, and directly heating again is so reduce coking, abundant burning coal;

Three, face arch lower collecting box height drops to 250mm, for this reason, prevents to burn out coal bunker;

Four, the second-time burning because cross pipe shelves resistance grey black is strile-backd so reduced oke exhaust blackness, has improved environment protecting.

Five, heat transfer coefficient height can reach 200 kilocalories/m ²Hc, bigger about 2.5 times than general boiler, the thermal efficiency improves more than 10%.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1,2,3,4 is respectively the front perspective view after explanation the utility model specific embodiment different model boiler improvement.

Describe concrete structure of the present utility model in detail below in conjunction with accompanying drawing:
