Abstract
The utility model relates to a powered fuel combustion-supporting feeding device, containing a feeding-tube (7), a blast pipe (8), a firing oil-gas pipe (6), and a flare-lance (5). The device is characterized in that in the discharging port of the feeding-tube is equipped with a combustion cylinder, which upper part connects with feeding-tube hermetically, and the lower part is open. In the outer casing of the combustion cylinder (1) is equipped with a water jacket (2), which the internal wall is equipped with a refractory layer (3). Inside of the refractory layer is the inner cavity (10) of the combustion cylinder. On the end head of the firing oil-gas pipe, and near the discharging port of the feeding-tube is equipped with a distribution dong (11). Outside the casing of the combustion cylinder is equipped with a water inlet (4) and an outlet (9), and the inlet and the outlet connect with the water jacket. The utility model is applicable to the boilers that use powdered fuel. The utility model is characterized in improving the combustion efficiency, saving the fuel, and is good for environmental protection.
Description
Technical field
The utility model belongs to a kind of burner, and concrete is the dusty fuel burner that a kind of boiler uses.
Background technology
The use of coal-burning boiler at present is still very general, and a lot of coal-burning boilers use dusty fuels such as coal dust, oil dregs of fat powder or both mixtures to act as a fuel.Need a feeding device during operation or make the device of burner that dusty fuel is sent into burner hearth or combustion chamber.The dusty fuel feeding device that uses mostly is directly fuel to be blown into burner hearth at present.This structure has its practicality, and is better in stove internal combustion situation, generally can move preferably under the more prosperous situation of the intensity of a fire.But it comes with some shortcomings, and particularly often fuel can not fully burn; Particularly in the stove under the more weak situation of the intensity of a fire, or under the situation of underrun, fuel is can not clean-burning situation even more serious, sometimes even the existing picture of fire extinguishing takes place.Cause waste easily like this, what also influence was produced normally carries out.Therefore, need improve existing dusty fuel feeding device.
The utility model content
The purpose of this utility model is at the problems referred to above, a kind of dusty fuel efficient burning device is proposed, this device is by being provided with a combustion barrel, dusty fuel is introduced into combustion barrel and lights, send into burner hearth again, make fuel in burner hearth, form best fired state, thereby solve the problem that fuel can not fully burn and put out a fire.
The purpose of this utility model solves by the following technical programs: a kind of dusty fuel efficient burning device, be provided with feed pipe, blast pipe, igniting oil gas pipe, burning torch, it is characterized in that: the discharging port position at described feed pipe is provided with a combustion barrel, the upper end of this combustion barrel and feed pipe and air inlet pipe are tightly connected, lower ending opening, the housings of this combustion barrel is provided with a water jacket, the inwall the inside of this water jacket is provided with a flame retardant coating, the flame retardant coating the inside is the inner chamber of combustion barrel, described igniting oil gas pipe stretches into the inner chamber of combustion barrel through the discharging port from the centre of air inlet pipe, in the discharging port of igniting oil gas pipe end near feed pipe, be provided with a sub-material shield, the fuel that this sub-material shield will enter combustion barrel is broken up; Be provided with water inlet and delivery port in the outside of described combustion barrel shell, this water inlet and delivery port communicate with described water jacket.
In addition, a whirlwind retaining is set, makes the air that is blown into enter combustion barrel equably, can produce better combustion efficiency in the exit of described blast pipe; At the shell end opening edge of described combustion barrel a flange plate-like convex edge is set, combustion barrel is fixedlyed connected with the combustion chamber or the burner hearth of boiler.
The utility model, can blaze up in the combustion barrel of high temperature after dusty fuel is admitted to this combustion barrel at once owing to be provided with a combustion barrel, when entering in the burner hearth again, can reach best fired state very soon, and can fully burn, and discharges net quantity of heat.When the boiler initial launch, or during underrun, under the situation that temperature is not too high in the burner hearth,,, also will blaze up, thereby guarantee to be in fired state preferably all the time in the burner hearth of boiler as long as dusty fuel enters because the volume of combustion barrel is less.On described combustion barrel barrel, be provided with flame retardant coating and water jacket, can make combustion barrel be not easy to be burnt out,, can lower the temperature, can also obtain hot water, also guaranteed the long-term normal operation of combustion barrel to combustion barrel by the recirculated water in the water jacket.Therefore, the utility model compared with prior art has novel and reasonable structure, can guarantee the normal operation of boiler, guarantees that the fuel in the boiler burns more fully, further improves efficiency of combustion, thereby also with regard to energy savings, is beneficial to the advantage of environmental protection again.
Description of drawings
Fig. 1 is an internal structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further: embodiment: referring to accompanying drawing, a kind of dusty fuel efficient burning device, be provided with feed pipe 7, blast pipe 8, igniting oil gas pipe 6, burning torch 5, discharging port position at described feed pipe is provided with a combustion barrel, the upper end of this combustion barrel and feed pipe and air inlet pipe are tightly connected, lower ending opening, shell 1 the inside of this combustion barrel is provided with a water jacket 2, the inwall the inside of this water jacket is provided with a flame retardant coating 3, the flame retardant coating the inside is the inner chamber 10 of combustion barrel, described igniting oil gas pipe stretches into the inner chamber of combustion barrel through the discharging port from the centre of air inlet pipe, in the discharging port of igniting oil gas pipe end near feed pipe, be provided with the sub-material shield 11 of a cone shape, this sub-material shield is in order to break up the fuel of sending into combustion barrel, it is sprinkling upon in the combustion barrel equably, is provided with water inlet 4 and delivery port 9 in the outside of described combustion barrel shell, this water inlet and delivery port communicate with described water jacket; Be provided with whirlwind retaining 12 in the exit of described blast pipe, these whirlwind shelves make air enter inner chamber equably; Be provided with a flange plate-like convex edge 13 at the shell end opening edge of described combustion barrel, in order to the utility model is fixed in the burner hearth of boiler.Air inlet is connected with blower fan, and feed pipe is connected with air blast with the hopper of feeding.
The utility model can be designed to different size according to the size and the operation needs of matching used boiler, and the position of installing in boiler furnace also can be adjusted flexibly.Through evidence, boiler of the present utility model is installed, its efficiency of combustion, coal saving rate is significantly improved, and the flue dust of discharging also obviously reduces.
