The advantages of the invention are high heat efficiency, and decreased consumption within combustion unit time.

Description

A kind of coagulating type hot-water boiler

Technical field

The present invention relates to a kind of boiler, specifically be meant a kind of coagulating type hot-water boiler.

Background technology

At present, China's internal combustion type hot-water boiler occupies sizable ratio, and internal combustion type hot-water boiler smoke pipe all is top or the right and left that comes burner hearth, causes boiler thermal output low.

Summary of the invention

The purpose of this invention is to provide and to reduce exhaust gas temperature, make a kind of coagulating type hot-water boiler of the high efficiency fuel oil (gas) that the latent heat of vaporization of condensate water recycled.

Design of the present invention is, it mainly is made up of combustor, inner core (being burner hearth), smoke pipe, smoke box, urceolus, inner core is arranged on upper of furnace body, and smoke pipe is in the inner core bottom, and smoke pipe is by entering the mouth to port of export low dip, weld with internal tube plate, outer tube plate respectively at its two ends, the condensate water water fender is housed on the outer tube plate, and the condensate water outlet is arranged at the bottom, and water inlet is arranged on the urceolus of bottom of furnace body, the position is below the smoke pipe outlet flue, and delivery port is arranged on the urceolus at body of heater top.

Description of drawings

Below in conjunction with accompanying drawing the present invention is described in detail.

Fig. 1 is an outward appearance schematic top plan view of the present invention;

Fig. 2 is the main cross-sectional view of looking of the present invention;

Fig. 3 is that Fig. 2 B is to schematic diagram;

Fig. 4 is Fig. 2 A-A section and part section structural representation;

Among the above-mentioned figure, 1-combustor, 2-fixed head, 3-outer tube plate, 4-refractory material, 5-exhanst gas outlet, 6-inner core, 7-urceolus, 8-delivery port, 9-water inlet, 10-smoke pipe, 11-internal tube plate, the outlet of 12-condensate water, 13-corrugated plate, 14-water fender, 15-smoke box.

The specific embodiment

Embodiment:

Referring to Fig. 1-Fig. 4, the present invention it mainly by combustor 1, inner core 6, smoke pipe 10, smoke box 15, urceolus 7 is formed, combustor 1 usefulness bolt directly is fixed on body of heater inner core 6 fixed heads 2, inner core 6 is arranged on upper of furnace body, smoke pipe 10 is in inner core 6 bottoms, be inserted with in it and switch political loyalty apart from corrugated plate 13, smoke pipe 10 is by entering the mouth to port of export low dip, its two ends respectively with internal tube plate 11, outer tube plate 3 welding, inner core 6 is sealed by interior end socket with internal tube plate 11, form combustion chamber, smoke box 15 is screwed outside smoke pipe 10 outlet flues of bottom of furnace body, and condensate water water fender 14 is housed on the outer tube plate 3, and the condensate water outlet is arranged at the bottom, opposite side has exhanst gas outlet 5, urceolus 7 is arranged on the boiler skin, and water inlet is arranged on the urceolus 7 of bottom of furnace body, and the position is below smoke pipe 10 outlet flues, delivery port 8 is arranged on the urceolus 7 at body of heater top, water inlet 9 and delivery port 8 and inner core 6, the space that urceolus 3 is contained communicates.

Inner core 6 oral areas are equipped with the refractory material 4 that can wrap up combustor 1 combustion head, are used for insulation and protect combustor 1 combustion head not burnt out.

The course of work of the present invention is, urceolus 7 and inner core 6 before the running, the space that smoke pipe 10 contains has been full of filtered clear water, when combustor 1 is started working, send into the fuel and the air mixed combustion of inner core 6, form thermal-flame, heating surface transmits heat towards periphery simultaneously, consequent high-temperature flue gas enters downwards in the smoke pipe 10 through inner core 6 outlets, flue gas carries out heat exchange by the water of smoke pipe 10 and smoke pipe 10 peripheries, water is heated, switch political loyalty apart from corrugated plate 13 because of being equipped with in the smoke pipe 10, high-temperature flue gas flow velocity when the corrugated plate 13 progressively slows down, and has prolonged the heat-exchange time of flue gas and smoke pipe, makes that most of heat is absorbed by water in the flue gas, flue gas becomes low-temperature flue gas when smoke pipe 10 comes out, low-temperature flue gas is discharged through the exhanst gas outlet 5 of smoke box 15.Steam in the flue gas produces condensation heat transfer, heating surface is sent the heat that is absorbed back to boiler, when reducing exhaust gas temperature, has improved the thermal efficiency of boiler, the condensate water that the flue gas heat exchange produces flows into smoke box 15 through the smoke pipe 10 and the water fender 14 of low dip, discharges from condensate water outlet 12.

The present invention is owing to reduced the exhaust gas temperature of boiler, and thermal efficiency height has reduced the consumption in the burning unit interval, so can save operating cost, increases economic efficiency, and meets the requirement of environmental protection development.
