Abstract

The utility model discloses a horizontal fire tube boiler, which comprises a stove bottom seat (1), a fire grate (2), a stove chamber (3), a water tank (6), a pressure meter (7), a safety valve (8), a steam tube (9), a flue (10), a drainage valve (11), a water level controller (12), a water inlet tube (13), a drainage tube (14), etc. The utility model is characterized in that a box body (4) is used as a stove wall of the stove chamber (3); work medium in the box body (4) is mutually communicated with the water tank (6) through a communication tube (5); the outside of a flue pipe in the flue (10) is distributed with heat radiation sheets; heat energy in the flue (10) is converted into hot wind through a blower; then the heat energy is transported to the stove chamber (3). The burning temperature of coal of the utility model is higher by more than 200DEG compared with that of the existing similar stove chamber of a boiler. The heat energy utilization of the utility model is improved.

Description

A kind of horizontal tubular boiler

The utility model belongs to the Industrial Boiler field.

Industrial Boiler is divided into two kinds of multitubular boiler and water-tube boilers with regard to its body construction.In multitubular boiler, high-temperature flue gas flows in fire tube (also claiming flue or fire tube) and smoke pipe, with the mode heating working medium of radiant heat transfer and convection heat transfer' heat-transfer by convection.By Shanghai Communications University, Xi'an woods ancestor tiger, open that license-master forever compiles " the boiler handbook describes the structure and the pluses and minuses of various Industrial Boiler in detail (China Machine Press, in February, 1989).Boiler is made of critical piece and servicing unit.Industrial Boiler is taken into account various adapters, valve etc. by furnace shell cylindrical shell, furnace base, flue, fire grate, Pressure gauge, thermometer, liquid level and is constituted.The Industrial Boiler master-plan should be to improve boiler efficiency (energy-conservation) and save steel on safe and reliable basis in principle.But also there is following defective in the horizontal boiler on market at present: 1, the heat absorption of refractory brick furnace wall does not too much make full use of heat energy; 2, a large amount of heat energy are discharged by flue; 3, bulky, the manufacturing expenses material, take a lot of work, during installation fee; 4, safeguard cleaning trouble, time-consuming; 5, service life is short etc.

Task of the present utility model is to provide a kind of horizontal tubular boiler, and its heat energy utilization rate height is made simply, and installation and maintenance are convenient, long service life.

For finishing above-mentioned task, the solution that the utility model is taked is: a kind of horizontal tubular boiler, comprise furnace base, fire grate, burner hearth, water tank, Pressure gauge, safety valve, steam pipe, flue, blowoff valve, water level controller, water inlet pipe and drainpipe etc., it is characterized in that with the furnace wall of casing as burner hearth, working medium communicating pipe and water tank intercommunication in the casing, the outer cloth fin of smoke pipe in the flue is that hot blast is delivered to burner hearth by air blast with the thermal power transfer in the flue.

The utility model since casing as the furnace wall, the heat energy in the burner hearth directly heats working medium in the casing and produces steam and reach water tank, than existing with the boiler heat energy utilization rate height of refractory brick as the furnace wall; Utilize the outer fin of flue tube, make full use of heat energy, make the thermal power transfer of flue discharging become hot blast, utilize hot blast combustion-supporting, the increase in temperature that can make coal combustion in the burner hearth is more than 200 ℃; Owing to utilize above-mentioned two technology, the boiler of identical tonnage, the quantity of steam that the utility model produces improves greatly, and volume-diminished, weight saving, easy to manufacture, easy for installation, and correspondingly prolong service life.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.

Accompanying drawing is the structural representation of present embodiment.

As shown in the figure, the available brick mix structure of furnace base (1), on put fire grate (2), constitute the furnace wall of burner hearth (3) with casing (4), also available cylindrical shell replaces casing (4), the outer wall heat-barrier material of casing (4), casing (4) has down partly the place water pipe (14) that runs in, have and pacify blowoff valve (11) outside the place, casing (4) top has a place to tap into water pipe (13), put water tank (6) on the casing (4), water tank (6) is cylindrical, water tank (6) is communicated with communicating pipe (5) with casing (4), present embodiment is with 5 communicating pipe (5), wherein use the casing (4) that is communicated with both sides 1 communicating pipe (5), water level controller (12) is pacified in the place suitable on the top, side of water tank (6), at a place on water tank (6) top peace Pressure gauge (7), one disposes safety valve (8), one place connects steam pipe (9), one disposes flue (10), the outer cloth fin of flue tube in the flue (10) becomes hot blast to be delivered to burner hearth (3) thermal power transfer in the flue by air blast.

Claims (1)

1, a kind of horizontal tubular boiler, comprise furnace base (1), fire grate (2), burner hearth (3), water tank (6), Pressure gauge (7), safety valve (8), steam pipe (9), flue (10), blowoff valve (11), water level controller (12), water inlet pipe (13) and drainpipe (14) etc., it is characterized in that: with the furnace wall of casing (4) as burner hearth (3), the interior working medium of casing (4) communicating pipe (5) and water tank (6) intercommunication; The outer cloth fin of flue tube in the flue (10) is that hot blast is delivered to burner hearth (3) by air blast with the thermal power transfer in the flue (10).
