Abstract
The invention relates to a vortex diffusion combustion boiler, which relates to the technical field of heating and heat supply and utilization, in particular to a structure of a boiler. The vortex diffusion combustion boiler comprises a shell, wherein a furnace liner is arranged inside the shell; a high-magnesium composite aluminum silicate layer is arranged on the internal surface of the furnace liner; nozzles are arranged at the front end of the furnace liner; and a tungsten alloy separating screen is arranged inside the furnace liner and is arranged on the rear side of the nozzles. In the vortex diffusion combustion boiler, the front edge of a combustion flame is diffused by the tungsten alloy separating screen in a form of high-temperature heat flow and then enters a water-cooled wall inside a furnace chamber, so that temperature difference between an inner flame and an outer flame is eliminated, and flameless combustion under working conditions is realized. The vortex diffusion combustion boiler has the advantages that: the service life of steel of the furnace liner is prolonged; the high-temperature radiation length is shortened by half and the capacity of the furnace liner of a boiler body can be shortened by about a quarter by changing a flame density radiation angle, and cost is saved; and the radiation temperature inside a hearth is in an intermediate-temperature working condition state, NOX is hardly discharged, and the vortex diffusion combustion boiler meets the requirements of a product recommended by the national environmental policy.
Description
Technical field
The present invention relates to heating, heat supply utilizes technical field, relates in particular to the structure of boiler.
Background technology
At present with the adjustment of China's development of the West Regions, transfering natural gas from the west to the east national energy policy, the protection environment, prevent and remedy pollution, energy-saving and emission-reduction, improve a series of laws and regulations such as resource utilization, become the core that instructs of national energy policy.09 year statistics of tool national energy portion shows, domestic market industry at present and coal consumption of living reach 6.5 hundred million tons/year, account for 40% of the former product of coal of China, annual newly-increased 1.0-1.6MPa grade fuel oil, gas fired-boiler are the utilization of more than 9.5 ten thousand (about 180,000 steam ton) energy, the utilization rate of heat energy has fettered the performance assessment criteria that China's limited resources use, existing boiler exist service life short, the thermal efficiency is low, not environmental protection, defect of high cost.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, the vortex diffusion combustion boiler of a kind of thermal efficiency height, environmental protection and saving cost is provided.
The object of the present invention is achieved like this: a kind of vortex diffusion combustion boiler, comprise shell, flue is set in the shell, the inner surface of flue is provided with high magnesium complex silicate aluminium lamination, in the front end of flue shower nozzle is set, the tungsten alloy bolter also is set in the described flue, and the tungsten alloy bolter is arranged on the rear side of shower nozzle.
The forward position that the present invention makes combustion flame enters water-cooling wall in the furnace chamber with the form of high-temperature heat flux after by the tungsten alloy bolter, realizes the flameless combustion under the operating mode.Make former general 45 ℃ of nozzles when lighting temperature 1200-1500 ℃, the length of flame (exerting oneself by 1.4MW) is 1.1m～1.8m * ￠ 0.3～0.6m, by the change of matter has taken place behind the combustion-supporting vortex diffuser, forming nonflame high-temperature heat flux length (exerting oneself by 1.4MW) is: the high temperature heat radiation stream of 0.8 ~ 1.0M, the burning radiation temperature is about 850 ℃, its advantage is: one, flame is when burning, and the flame envelope temperature is for the highest, and the temperature difference of flame envelope and internal flame forms visual luminance difference.At this moment, flue at the close position of flame will bear stronger high temperature thermal shocking, go down for a long time, just cause local material aging in advance, influence boiler service life. and after flame spreads by the tungsten alloy bolter, pulverized the temperature difference between internal flame and the flame envelope, become the form of invisible hyperthermia radiation, pass through the thermal power transfer of built-in energy storage room again, having reduced burner hearth localized hyperthermia on the one hand washes away, make the temperature of burner hearth be able to balanced stray radiation, avoid former flue washed away by high temperature and caused the tired fast phenomenon of flue material, be improved, delayed the service life of flue steel, secondly pass through the change of flame density radiation angle, hyperthermia radiation length is able to the shortening of 1/2 ratio, boiler body structurally can shorten nearly 1/4 courage appearance size, so after having adopted this combustion technology, since can reach the prolonged boiler purpose in service life, can shorten flue length again, on manufacturing cost, reach a conclusion through test, can save boiler steel 1/4, they are two years old, since flame lead in built-in tube after the realization primary combustion carry out the secondary diffusive separation through the vortex diffuser after, pulverized the temperature difference between internal flame and the flame envelope, make the interior radiation temperature of its burner hearth be in warm operating mode form in, its NO
XDischarge capacity very little, meet the requirement of national environmental protection policy recommended products.They are three years old, owing to adopting former boiler to take to extend the flue size and the dirty three backhaul fire tube versions of taking of a large amount of rings of band band not to the utmost of avoiding burning, so both technological requirement height, cost is big, cause the body of heater volume excessive again, structure easily causes the booster fault and shortens boiler service life between smoke pipe and tube sheet wall, and take type to spread the atomized spray angle, change into the heat conduction of secondary radiation formula by an injecting type burning in burning in form, take to make atomizing to change gasified combustion into, flame is again by after the two subthermal energy vortex diffuser diffusions, but 15 ﹪ through tungsten alloy diffusive separation screening big total heating surface of energy emission face altar after carrying out power conversion by the heat energy radiation of built-in energy storage room, like this, can take two return just can realize the effect of three backhauls, both save the sheet material materials, optimized process structure again.
