Abstract

The invention discloses a smokeless hot-water boiler, which comprises a chimney, a furnace body, a hearth and an air blowing port, wherein a coal inlet and an ash outlet are formed on the lower part of the furnace body; an inner furnace body is arranged in the furnace body; a sealed externally-annular outer water tank is formed between the inner furnace body and the furnace body; and the inner furnace body is insulated into three combustion chambers through a first water tank, a second water tank and a third water tank. As the smokeless hot-water boiler is provided with the three combustion chambers for high-temperature combustion, fume and floccule stay in the combustion chambers for a longer time and are fully combusted to be converted into heat energy and transparent gas. As the smokeless hot-water boiler is provided with the outer water tank and a plurality of inner water tanks, water in the boiler is gradually heated in a step-by-step heating manner, so that the hot water supply efficiency is greatly improved, the water continuously outflows, and the ratio of coal to the water is 1:300; and the smokeless hot-water boiler saves the coal by 70 percent higher than that of a steam boiler and saves the coal by 30 percent higher than that of a common hot-water boiler.

Description

A kind of smokeless hot-water boiler

Technical field

The present invention relates to a kind of boiler, specifically is a kind of smokeless hot-water boiler.

Background technology

Coal is when burning just; Coal tar and other impurity form both floccules of black smoke in low temperature, all to exist coal insufficient in the burner hearth internal combustion for used water heater of each bathing pool and steam boiler at present, and heat exchange area is little; The thermal efficiency utilizes problems such as low; Fumigation because in burner hearth the time of staying short, directly emit from flue, not only wasted coal but also contaminated environment.

Summary of the invention

To the problem that above-mentioned prior art exists, the present invention provides a kind of smokeless hot-water boiler, and no fumigation is got rid of, and heat exchange area is big, economic environmental protection.

To achieve these goals, the technical scheme of the present invention's employing is: a kind of smokeless hot-water boiler comprises: chimney, body of heater, burner hearth, water filling port; The body of heater bottom has coal feed point and ash hole, also is provided with blowing mouth, and burner hearth inside is provided with many fire grate pipes that laterally arrange horizontal; Also be provided with inner furnace body in the body of heater; Form the outer water tank of a sealing cylindrical annular between described inner furnace body and the body of heater, body of heater has the water filling port that connects outer water tank outward, and inner furnace body completely cuts off into first combustion chamber, second combustion chamber, the 3rd combustion chamber to inner furnace body successively through first water tank, second water tank, three-tank; Described first water tank, second water tank, three-tank communicate through a plurality of connection water pipes; Interior water inlet pipe is arranged on the top of outer water tank and is communicated with first water tank, and three-tank sets out water pipe, and described first combustion chamber, second combustion chamber and the 3rd combustion chamber communicate successively through breather pipe and link to each other with burner hearth; The 3rd combustion chamber links to each other with chimney, also is provided with air bleeding valve.

Further, the 3rd combustion chamber is provided with air bleeding valve.

The present invention is provided with a plurality of combustion chamber high temperature burnings, and it is longer that fumigation and floccule can stop in the combustion chamber, and then fully burn fumigation and floccule; Change into heat energy and transparent gas, the present invention also is provided with outer water tank and a plurality of inner water tank, heats step by step through interior outer water tank; Water in the boiler is progressively heated, improved the efficient that hot water greatly, water outlet is uninterrupted; Coal-water ratio is 1:300, economizes on coal 70% than steam boiler, economizes on coal 30% than common water heater.

Description of drawings

Fig. 1 is a structural representation of the present invention.

Among the figure: 1, body of heater, 2, water filling port, 3, blowing mouth, 4, ash hole, 5, coal feed point; 6, first water tank, 7, outer water tank, 8, burner hearth, 9, first combustion chamber, 10, second water tank; 11, second combustion chamber, 12, three-tank, the 13, the 3rd combustion chamber, 14, chimney, 15, air bleeding valve; 16, interior water inlet pipe, 17, fire grate pipe, 18, outlet pipe, 19, be communicated with water pipe, 20, breather pipe.

The specific embodiment

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

As shown in Figure 1, a kind of smokeless hot-water boiler comprises chimney 14, body of heater 1, burner hearth 8; Body of heater 1 bottom has coal feed point 5 and ash hole 4; Also be provided with blowing mouth 3, burner hearth 8 inside are provided with many fire grate pipes 17 that laterally arrange horizontal, also are provided with inner furnace body in the body of heater; Form the outer water tank 7 of a sealing cylindrical annular between described inner furnace body and the body of heater 1; Body of heater has the water filling port 2 that connects outer water tank 7 outward, and first water tank 6 of inner furnace body setting, second water tank 10, three-tank 12 completely cut off into first combustion chamber 9, second combustion chamber 11, the 3rd combustion chamber 13 to inner furnace body successively, and described first water tank 6, second water tank 10, three-tank 12 communicate through a plurality of connection water pipes 19; One end of interior water inlet pipe 16 is arranged on the top of outer water tank 7; The other end is communicated with first water tank 6, and three-tank 12 sets out water pipe 18, and described first combustion chamber 9, second combustion chamber 11 communicates through breather pipe with the 3rd combustion chamber 13 successively and link to each other with burner hearth 8; The 3rd combustion chamber 13 links to each other with chimney 14, but also is provided with air bleeding valve 15.

At first inject water from water filling port 2 during use and get into outer water tank 7, by the time water is added to when surpassing interior water inlet pipe 16 tops, water will get into first water tank 6 from interior water inlet pipe 16, and gets into second water tank 10 and the three-tank 12 through pipeline successively, goes out from outlet pipe 18.Heating system is to get into first combustion chamber 9, second combustion chamber 11 and the 3rd combustion chamber 13 successively from the heat of burner hearth 8 burning and black smoke, and when furnace pressure was excessive, air bleeding valve 15 can be opened step-down; Because the combustion chamber heat is big, and fumigation can be longer in the time of staying of three combustion chambers, so burning fully; Change into heat energy and transparent gas to fumigation, improved heat utilization efficiency, the present invention progressively heats through interior outer water tank; Improved the efficient that hot water greatly, water outlet is uninterrupted, and coal-water ratio is 1:300; Economize on coal 70% than steam boiler, economize on coal 30% than common water heater.
