Abstract

The utility model relates to a living furnace, especially to a coal-fired smokeless environment-friendly boiler. The utility model is characterized in that two layers of furnace chambers 10, 13 that are superposed from top to bottom are installed in the furnace and an upper furnace chamber 13 and a lower furnace chamber 10 are same in shape and structure and are both made by welding a circular platform and a circular cylinder. A furnace door 2, a grate, an ash outlet and a water outlet pipe are installed in the lower furnace chamber 1 to form a first burning chamber 20; an air inlet 3, a fire aggregating opening 7, a fire aggregating chamber 19 and a heat conducting pipe 14 are installed in the upper furnace chamber 13 to form a second burning chamber. The carbon at the lower part of a glowing coke layer produces an oxidation reaction with the oxygen in the air to generate the carbon dioxide and the carbon monoxide and emits a large amount of heat in the process of burning the coal in the grate of the first burning chamber 20. As the temperature of the reaction is continually raised quickly and the density of the oxygen in the furnace chamber is steadily degraded till the density of the oxygen is close to zero, the generated carbon dioxide and the carbon monoxide are increased steadily to be aggregated at the fire aggregating opening whose diameter is 100mm in the second burning chamber while the air inlet installed near the fire aggregating opening loses no time in supplying appropriate oxygen to make the carbon dioxide and the carbon monoxide burnt continuously in the second burning chamber 18. The fire after being burnt is aggregated in the fire aggregating chamber 19 to enhance the temperature of the heat guiding pipe 14 to achieve the purpose of raising the temperature without smoke and saving energy.

Description

A kind of smokeless environment-friendly boiler

Affiliated technical field: utility model technical field: the energy-efficient smokeless environment-friendly boiler that the present invention relates to a kind of boiler, particularly coal-fired usefulness.

Background technology: in combustion process, the carbon of scorching hot coke layer bottom and airborne oxygen generation oxidation reaction, generate carbon dioxide and carbon monoxide, and emit a large amount of heats, along with the continuation of reaction, temperature is assembled rapidly, produce a large amount of black smokes that has and enter atmosphere, because burning is insufficient, cause energy waste on the one hand, produce air pollution on the other hand.

Summary of the invention: the purpose of this utility model provides a kind of efficient burning smokeless environment-friendly boiler, helps energy savings, improves efficiency of combustion, reduces or avoids sufficient carbon dioxide of unburned and carbon monoxide to enter air, causes air pollution.

The object of the present invention is achieved like this, it is at least by furnace shell, flue, burner hearth, fire grate, heat pipe, exhaust opening, it is characterized in that being provided with in the boiler two-layer burner hearth up and down, upper furnace is identical with the formation shape of lower hearth wall, constitutes by a round platform and cylinder.Be provided with first combustion chamber of fire grate, fire door, outlet pipe, ash hole formation boiler in the column part of lower hearth, round platform partly is arranged to group kitchen range chamber that certain taper constitutes boiler; Be provided with second combustion chamber of air inlet, poly-burner formation boiler in the barrel portion of upper furnace, be provided with the poly-fiery chamber of heat pipe, water inlet pipe, chimney formation boiler in the round platform part.Constitute the flue of boiler between burner hearth shell and the boiler jacket.In the process that coal burns in the fire grate of first combustion chamber, the oxygen generation oxidation reaction of the carbon of scorching hot coke layer lower part and air, generate carbon dioxide and carbon monoxide, and emit a large amount of heats, continuation with reaction, temperature rises rapidly, and the concentration of oxygen constantly descends until near null value, carbon dioxide that generates and carbon monoxide descend disconnected increasing and upwards gather in the gathering mouth of second combustion chamber, being arranged on the gathering mouthful suitable oxygen of passing to that the ventilating opening of locating is let slip no opportunity this moment burns away carbon dioxide and carbon monoxide, owing in burner hearth, be provided with poly-burner and ventilating opening, reach the purpose of abundant comburant burning.Increase the utility time of cigarette simultaneously, the flue temperature raises.Energy-saving free of smoke boiler according to design of the present utility model, can be suitable for the heat transmission equipment of various models, all can reach sufficient combustion, no flue dust discharging, can suppress the generation of nitrogen oxide, facts have proved through the experiments of decades, utilization property is strong, applicability wide, energy savings, cheap, not contaminated air, vast market is arranged, very high economic benefit and social benefit is arranged.

Description of drawings:

The utility model is described in further detail below in conjunction with embodiment

Fig. 1 is the utility model isometric front view

Fig. 2 is that the utility model is implemented structural representation

The top of boiler is provided with chimney 6, water inlet pipe 5 and gas outlet 4 in Fig. 1, and the middle part is provided with air inlet 3, and the bottom is provided with fire door 2, ash hole 12, boiler support 11 and outlet pipe.

Be provided with two-layer burner hearth 10 and 13 up and down in Fig. 2, upper furnace 13 and lower hearth 10 constitute by

round platform

8,15 and cylinder 16,17.The fire door 2, outlet pipe, the ash hole that are provided with fire grate, 200 * 200mm in the cylinder of lower hearth 10 have constituted first combustion chamber 20 of 400 * 550mm of lower hearth 10, and its Rotary-table is arranged to group kitchen range chamber 9 of the round table-like formation boiler of certain taper; Be provided with second combustion chamber 18 that air inlet 3, poly-burner 7 constitute 240 * 250mm of boilers 1 in the cylinder of upper furnace, the chimney interface 6 that is provided with diameter in the round platform and is 100mm heat pipe 14, water inlet pipe 5, diameter and be 100mm constitutes the poly-fiery chamber 19 of boilers 1.Furnace shell 1 is around constituting the flue that can hold more water between the burner hearth.

In the process that coal burns in the fire grate of first combustion chamber 20, the carbon of scorching hot coke layer bottom and airborne oxygen generation oxidation reaction, generate carbon dioxide and carbon monoxide, and emit a large amount of heats, along with the continuation temperature of reacting rises rapidly, and the concentration of oxygen in the burner hearth constantly descends until near null value, carbon dioxide that generates and carbon monoxide are on the increase and the diameter that upwards gathers is the poly-jet-burner of 100mm second the combustion chamber in, be arranged near the suitable oxygen of supply that the ground air inlet is let slip no opportunity the poly-burner this moment carbon dioxide and carbon monoxide are burnt away in second combustion chamber 18.Fire after the burning accumulates in the temperature that rises merchant's heat pipe 14 in the fiery chamber 19 and reaches smokeless intensification, purpose of energy saving.
