Abstract
The invention provides a blast-injecting forced-advancing full pre-mixing energy-saving combustor which comprises a main cavity, a blast pipe, a fuel gas pipe, a nozzle, a fire distributor and a firing needle, wherein the blast pipe and the fuel gas pipe are connected with the main cavity; the nozzle is connected with the fuel gas pipe; and the fire distributor and the firing needle are arranged at the top of the main cavity. The blast-injecting forced-advancing full pre-mixing energy-saving combustor is characterized in that a screen, a flow fixer and a gas flow mixer are sequentially arranged between the fire distributor and the nozzle in the main cavity; the caliber of the gas outlet end of the flow fixer is smaller than the caliber of a gas inlet end of the flow fixer; the flow mixer is a cylinder of which the diameter corresponds to the internal diameter of the main cavity; and a plurality of gas mixing holes are arranged vertically along the cylinder and the calibers of all gas outlet ends of the gas mixing holes are smaller than the calibers of all gas inlet ends of the gas mixing holes. By adopting the structure, the effects of the high efficiency, the energy conservation and the environment protection are achieved.
Description
Technical field:
The present invention relates to gas burner, specifically is a kind of blast-injecting forced-advancing full pre-mixing energy-saving burner.
Background technology:
The burner of existing gas-cooker generally has two kinds, first kind is the atmospheric burner of band induction tunnel, the burner diameter is about about Φ 100mm, (thermal intensity of fire port decision burner diameter), main by the kinetic energy suction air in certain amount of combustion gas from the nozzle ejection, form mist and cover ignition to the branch fire on the burner, generate the flame of originally lighting a fire, reach completing combustion, need supply a large amount of auxiliary airs, otherwise it is too high fume emission to occur, the thermal efficiency is low. and second kind is the infrared burner of band ejection type, the burner diameter is about about Φ 140mm, what it was taked is a kind of combustion method of full premix air, do not need auxiliary air, but be difficult to the primary air that reaches too much, though the former increases fume emission and thermal efficiency ratio, but its heat flow is restricted, the calorific intensity of burning pinkeye is low, the scope of regulating is smaller, and its stability is poor, needs measure to prevent cold tempering, hot tempering and take off fire, because both combustion systems are natures, the mixed of combustion gas and air is passive, the mist that its combustion gas and air form, its mixability is not high, and the flow velocity of mist is deceleration trend, and also having at the combustion gas injection is logical empty to the mixed air flue between the distributor, some is not set is beneficial to mist and strengthens decomposite device, simultaneously also because the pressure of fuel gas injection is limited, nozzle mostly is single hole, and porous can reduce the pressure of combustion gas spray body, add some devices after, can influence mix the flow velocity process of gas, thereby have influence on combustion conditions.
Summary of the invention:
Characteristics such as the objective of the invention is: a kind of blast-injecting forced-advancing full pre-mixing energy-saving burner is provided, and it can effectively improve the gas mixing intensity, accelerates gas flow rate, has high efficiency, hangs down and pollutes, and volume is little.
Technical scheme of the present invention is: a kind of blast-injecting forced-advancing full pre-mixing energy-saving burner, comprise main cavity, blast pipe that is connected with main cavity and Gas Pipe, the nozzle that joins with Gas Pipe, be positioned at the distributor and the igniting pin on main cavity top, it is characterized in that in main cavity, being disposed with screen cloth to the nozzle by distributor, constant current device and gas mixed flow device, the bore of the outlet side of described constant current device is less than the bore of its inlet end, the corresponding cylinder of internal diameter that described mixed flow device is diameter and main cavity, vertically offer a plurality of gas mixed holes along cylinder, the bore of all outlet sides of gas mixed hole is less than the bore of its all inlet end.
Described constant current device central authorities have up-small and down-big horn-like venting cavity.
Described gas mixed hole dwindles from bottom to top gradually.
In order to make the gas better mixing, on the gas mixed hole inwall, be provided with spiral helicine spring.Be provided with bulging spray booth in the premix chamber.
The present invention is owing to adopted said structure, be provided with bulging spray booth in the premix chamber, by in advance the ratio of gas quantity with the air capacity science being cooperated, fuel gas injection is divided into multiple jets, come the combustion gas mixing of blow air and injection with air blast or fan, promptly strengthen mixing kinetic energy field and provide power for the mist motion again, utilize the gas mixed hole of flow mixing device to improve the mixability and the speed of gas again, mist is evenly sprayed with fast speeds, shortened burning time, the combustion zone is with to be heated object distance nearer, heat conducting efficient higher (convection current conductivity and radiation conductivity all with square being inversely proportional to of distance), thereby realized efficient, energy-conservation, the effect of environmental protection.
