Description

The energy saving cold water gasification burner

Technical field

The utility model relates to coal furnace, particularly the energy-saving coal stove.

Background technology

The main power-economizing method that existing coal furnace adopts is the steam combustion supporting method, its principle is that steam generator is set in stove or outside the stove, the heat that utilizes stove to produce adds thermosetting steam with water, the water vapour of HTHP is sent in the burner hearth, water vapour contacts with red-hot coal, complex physico-chemical takes place, generate combustibles such as water-gas, hydrogen, water-gas includes carbon monoxide gas, make burning of coal that significant the variation be taken place, make full use of the potential of coal, thereby improve the burning of coal value, save coal.The shortcoming of above-mentioned these schemes is: must carry out structure of modification largely to body of heater, body of heater must be equipped with the water vapour pipeline and the withstand voltage valve of high temperature high voltage resistant, but also to be equipped with the pressure and the flow velocity of various instrument monitorings control such as Pressure gauge water vapours, the wayward adjusting of the generation of water vapour, when water vapor pressure is too high, also in time open pressure-reducing valve to prevent water steam, so the water vapour of HTHP brings hidden danger can for the safe handling of stove with pipe bursting.These equipment that are used to control to adjust water vapour can make the structure of body of heater become complicated, and the stove cost can rise, and water vapour is very strong to Corrosion of Pipeline, generate incrustation scale in pipeline easily, need often cleaning, and the maintenance expense also can raise.And water vapour also can lose some heats through piping the time, and these heats also are that coal burning produces in the stove, so relatively reduced the burning of coal value.There is the people to adopt in the present existing coal stove power-economizing method technology or contains the aqueous solution that helps energy-conservation composition and pack into and in container, be pressed into air behind the pressure vessel water, after fully being mixed, vapour-liquid is atomized into atomization gas, and enter air inlet duct is entered the combustion chamber by air inlet duct method by the nozzle of air inlet duct, but its shortcoming weak point is to need huge pressure vessel and go into the large air compressor that air is used to vessel internal pressure, so the method can only be used in the large scale industry boiler on the boiler more than several tons.And civilian home-use small coal can't be used this method.Reason is pressure vessel and air compressor volume greater than the several times of home-use commercial coal stove or tens times.Cost is too high, and volume is too big, and price is too high can't civil nature.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of energy saving cold water gasification burner is provided, it by gravitation drop hydraulic pressure and intermittently water pump realize that ultra-fine vaporize water sprays, steam is the cold water vapour of normal temperature, the gasification of cold water vapour is directly finished in body of heater, does not need to use steam generator, has saved large number quipments, the danger of having avoided using the water vapour of HTHP to cause, energy saving cold water gasification burner of the present utility model helps coal-fired fully burning, improves fuel value, save coal, dust-laying effect is good, and is simple in structure, and cost is low, applied widely, safe in utilization, convenient.

The purpose of this utility model is achieved in that a kind of energy saving cold water gasification burner, include body of heater, be provided with nozzle in the burner hearth of its body of heater, the spray orifice that ultra-fine aperture is arranged on this nozzle, this nozzle is connected with water tank outside being arranged on body of heater through water pipe, the position of this water tank is higher than the position of nozzle, and intermittently water pump is housed on water pipe.

The material of described nozzle is a nano material, and the spray orifice on the described nozzle is the spray orifice of nano-grade size.

Described nozzle has a plurality of, and they evenly distribute and are communicated in a ring pipe, and this ring pipe is arranged in the burner hearth, this ring pipe and described cross current.

Described ring pipe has many rows, and these ring pipes are separately positioned on different height and position place in the burner hearth, and these ring pipes all with described cross current.

The utility model has following actively useful effect:

1. cold water energy-saving gasfied stove of the present utility model is applied widely, can be used as the large scale industry boiler, heat power plant boiler, domestic burners uses, it utilize gravitation drop hydraulic pressure that the water in the water tank forms through intermittence water pump inject to the nozzle that has ultra-fine spray orifice, form vaporize water, ultra-fine normal temperature steam (cold water vapour) is sprayed in the coal seam in burner hearth, the gasification of ultra-fine cold water vapour is directly finished in body of heater, more help coal cinder or coal dust gasification, promote to take place in the high temperature furnace complex physico-chemical, produce water-gas and hydrogen gas mixture rapidly, coal is fully burnt, increase stove internal combustion value, save coal.

2. the vaporescence of the cold water vapour of normal temperature is directly finished in body of heater, the loss of heat when having avoided water vapour in pipeline, to transmit, more energy-conservation, it does not need to be provided with steam generator, it saves the vaporific process of boiling point that heats water to, thereby the various links that need such as various instrument, pressure piping, high pressure gas bag pressure force container and air compressor are manufactured with exotic material have been saved, not high to material requirements, save large number quipments, it is simple to have furnace binding than like product, and auxiliary equipment is few, and cost is low, processing and manufacturing is easy, easy-maintaining.Because of its burning mainly be the gaseous mixture of water-gas and hydrogen, therefore be used for can significantly improving energy-saving efficiency on existing large scale industry boiler, domestic burners, the heat power plant boiler, can save coal about 50 percent in theory, be convenient to extensive penetration and promotion.

3. energy-conservation stove of the present utility model and since directly with the normal temperature cold water in the water tank through pipeline by intermittence water pump be pressed into the superfine nozzle of spray orifice and form vaporize water and in stove, burn, do not need to control to adjust the water vapour of HTHP, safer in the use, make things convenient for.
