Abstract

The utility model relates to the improvement of a horizontal boiler. An arc-shaped reflecting arch with three to thirty throat openings with flower cavity pore canals is arranged above the hearth of the horizontal boiler. Three to thirty secondary air inlet pipes which form angles of 10DEG to 45DEG with the horizontal direction of the cross section of the hearth are arranged on a front wall and two side walls which have a distance of 50 mm to 100 mm under the reflecting arch. The boiler can be used for combusting inferior coal, and thermal efficiency reaches 76%. The utility model which eliminates black smoke improves environment.

Description

Horizontal boiler

The utility model relates to the improvement to a kind of horizontal boiler.

Usually horizontal boiler can not burning inferior coal, and coal-fired incomplete in the burner hearth internal combustion, the thermal efficiency is low.

The purpose of this utility model is to provide a kind of efficient horizontal boiler, but burning inferior coal is coal-fired complete in the burner hearth internal combustion, thermal efficiency height.

The utility model is to realize so in conjunction with the accompanying drawings.The one arc reflection arch made from refractory material 2 that has 3～30 colored hole road aditus laryngis 3 is arranged above burner hearth 1, under reflection arch on the antetheca and two side at 50～100mm place, be provided with 3～30 secondary wind inleting tubes 4, its direction of insertion becomes 10～45 with the cross section of burner hearth.

By the efficient horizontal boiler that said structure is made, because the top is provided with reflection arch in the burner hearth, fire box temperature can obviously improve, and can burn the colm of calorific value in 3000 kcal/kg; Above burner hearth antetheca and both sides, secondary wind inleting tube is housed, in burner hearth, can constantly replenish fresh air, and secondary wind inleting tube and hearth wall are angled, make flue gas be rotation status, concentrate, carbon granule, carbon monoxide combustible in the flue gas are fully burnt to reflection arch aditus laryngis place, thereby can make boiler thermal output reach 76%, and eliminated black smoke, reduced dust exhausting concentration, improved environment.

Description of drawings:

The efficient horizontal boiler structural representation of Fig. 1;

The left side of Fig. 2 Fig. 1 is looked and is partly cutd open figure;

The A-A of Fig. 3 Fig. 1 overlooks and partly cuts open figure.

Embodiment; Press structure shown in the accompanying drawing, as follows with the important technological parameters of the efficient horizontal boiler of 0.65 megawatt of exerting oneself;

Boiler overall dimensions length * wide * height=2450 * 1700 * 2500mm

Shell size length * wide * height=2390 * 1612 * 2164mm

Size of burner hearth length * wide * height=2390 * 1412 * 1296mm

Reflection arch adopts refractory concrete to make, and thickness 80mm has 7 circular openings on it, diameter ∮ 100mm.

13 ∮ 32 * 3 of rotation secondary wind inleting tube, direction of insertion becomes 20 ° of angles with sidewall;

36 of horizontal smoke pipes are arranged in the boiler, ∮ 159 * 5 two piece wherein, ∮ 108 * 4 six roots of sensation, ∮ 63 * 3.5 28 piece, length is 2400mm.

After tested, this boiler can burn the above any coal of calorific value 3000 kcal/kg, and heat supply is exerted oneself greater than 0.7 megawatt, and the thermal efficiency 77.8% can economize on coal 15～20% than horizontal boiler of the same type, the smoke evacuation compliance with environmental protection requirements.

Claims (1)

1, a kind of efficient horizontal boiler, it is characterized in that there is a reflection arch 2 that has 3～30 colored hole road aditus laryngis 3 burner hearth 1 top, on the antetheca and two side at 50～100mm place, be provided with 3～30 secondary wind inleting tubes 4 under reflection arch, its direction of insertion becomes 10～45 with the cross section of burner hearth.
