Abstract

The utility model provides a flame directly burns heating pipe, the heat absorption is efficient, the make full use of energy, the crossing heating pipe boiler that the steam production is big, this boiler is formed by the installation of essential element such as boiler barrel (1), heating pipe (2), cold wall pipe (3), lower header (4), furnace gate (5), grate (6), owing to become heating pipe (2) to the part cold wall pipe (3) of boiler to changed its connected mode, make flame direct heating pipe (2), the heat absorption efficiency of boiler has been improved, the steam production has been increased, a large amount of energy has been practiced thrift.

Description

Fork type heating pipe boiler

The utility model relates to a kind of boiler.

The present domestic boiler that adopts, its cold wall pipe is the both sides at body of heater, absorbs heat by radiation, heat absorption efficiency is very low, and when flame height was 400-700mm, the bottom of a pan was apart from fire grate 1000mm, the flame focus is too low, influences the bottom of a pan heat absorption, for a furfural production line of producing 1000 tons per year, designing supporting boiler is two, promptly steams 8 tons/hour, but the actual steam production that do not reach, steam production is very low, therefore three stove productions are joined by most producers, and coal is burnt in also replenishing of having, and has wasted a large amount of energy.

The purpose of this utility model be to provide a kind of flame directly to burn heating tube, heat absorption efficiency height, make full use of the energy, staggered form heating tube boiler that steam production is big.

The purpose of this utility model is to realize like this, this boiler is by drum, heating tube, cold wall pipe, lower collecting box, fire door, critical pieces such as fire grate are installed and are formed, its quantity of cold wall pipe and heating tube on every side on the drum and two lower linked box is each ten, the upper end of its heating tube links to each other with drum, the lower collecting box that passes the burner hearth other end and opposite links to each other, the cold wall pipe upper end links to each other with drum, the lower collecting box of the other end and the same side links to each other, on the lower collecting box on right side, count backward in the past, the left side lower collecting box on from after several forward first, three, five, eight, ten cold wall pipes are for tilting to connect, the gradient of its heating tube is 25 ° of angles, distance is 640mm between heating tube lower and the fire grate, on the heating tube, curved radius is R200mm down.

The utility model is owing to become heating tube to the part cold wall pipe of boiler, and changed its connected mode, makes flame directly heat heating tube, improved the heat absorption efficiency of boiler, increased steam production, saved a large amount of energy.No. 4, No. 5 quick-action furnaces of a DZG-13-K type make staggered form heating tube boiler into, can reduce 20-30 ℃ through the actual measurement exhaust gas temperature, and steam production improves about 0.8 ton, and it also has advantages such as simple in structure, easy to install simultaneously.

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

Fig. 1 is a staggered form heating tube boiler perspective view.

Fig. 2 is a staggered form heating tube boiler face perspective view.

Fig. 3 is a staggered form heating tube boiler heating tube connection diagram.

Describe specific embodiment of the utility model in detail below in conjunction with accompanying drawing, this boiler is by drum 1, heating tube 2, cold wall pipe 3, lower collecting box 4, fire door 5, fire grate 6 critical pieces such as grade are installed and are formed, as shown in Figure 1, its quantity of every side cold wall pipe 3 and heating tube 2 on drum 1 is each ten, the quantity of cold wall pipe 3 and heating tube 2 also is each ten on two lower collecting box 4, the upper end of its heating tube 2 links to each other with drum 1, the lower collecting box 4 that passes the burner hearth other end and opposite links to each other, cold wall pipe 3 upper ends link to each other with drum 1, the lower collecting box 4 of the other end and the same side links to each other, as Fig. 1, shown in 3, on the lower collecting box 4 on right side, count backward in the past, the left side lower collecting box 4 on from after several forward first, three, five, eight, ten cold wall pipes 3 are for tilting to connect, as shown in Figure 2, the gradient of its heating tube 2 is 25 ° of angles, distance is 640mm between heating tube 2 lowers and the fire grate 6, on the heating tube 2, curved radius is R200mm down.
