Description
Technical field:
The present invention relates to the combustion method and the equipment of glass melter, specifically a kind of method of solid fuel fusion cast glass and fuel feed system.
Background technology:
At present the used fuel of glass melter fusion cast glass is nothing more than following several: heavy oil, residual oil, coal tar or main be Solid-liquid Mixed Fuel and Sweet natural gas, producer gas or the coke-oven gas etc. of liquid phase with above-mentioned oil plant, because the converted products price of oil and coal is constantly soaring in recent years, makes the ratio of expense in the glass manufacturing cost of above-mentioned fuel increase substantially.
Summary of the invention:
The method and the fuel feed system that the purpose of this invention is to provide a kind of solid fuel fusion cast glass, can be under the prerequisite of steel construction that does not change original glass melter and brick structure, the powder (as coal, graphite etc.) of carbonic solid fuels directly sprayed in the kiln as the fuel of glass melter burn, thereby improve the utilization ratio of fuel significantly, reduce fuel cost, reduce the manufacturing cost of glass widely.
The present invention can reach by following measure:
A kind of method of solid fuel fusion cast glass is characterized in that adopting the air conveying method of concentrated phase that the powder of solid carbon fuel is directly sprayed into glass melter internal combustion fusion cast glass.
Fuel feed system of the present invention is: adopt the air conveying method of concentrated phase that the powder of solid carbon fuel is directly sprayed into glass melter internal combustion fusion cast glass, system is provided with the fuel filler bin, the winding-up jar, the fluidisation device, air reservoir, air compensation regulator, divider and solid powder burning spray gun, the winding-up jar is connected with the fluidisation device, the outlet of fuel filler bin is connected with a winding-up jar import through material guiding pipe, air reservoir is connected with the fluidisation device with the winding-up jar respectively through airway, the outlet of fluidisation device is connected with the air compensation regulator import through conduit, the air compensation regulator inlet mouth is connected with air reservoir through airway, the air compensation regulator outlet is connected with the import of pulverized fuel divider through conduit, the pulverized fuel divider is provided with some outlets, pulverized fuel divider outlet is connected with solid, powdery Fuel lance in the glass melter stove through conduit, and solid, powdery Fuel lance inlet mouth is connected with air reservoir through airway.
A winding-up jar upper end is provided with the air outlet among the present invention, winding-up jar air outlet through conduit and fuel filler bin inlet mouth be connected, with the charging of fuel metering filler bin.
The winding-up jar is provided with the pressure type LOAD CELLS among the present invention.
The present invention adopts above-mentioned concentrated phase pneumatic conveying method, has high solid-gas ratio, transfer rate is low, carry lasting, stable characteristics, because square being directly proportional of air conveying watt consumption and transfer rate, and be directly proportional with the 2-3 power of transfer rate for the wearing and tearing of pipeline, pipe fitting and valve, thereby adopt the air conveying energy consumption that has not only reduced course of conveying widely of concentrated phase, but also significantly reduced the wearing and tearing of pipeline, pipe fitting and valve.
Description of drawings:
Accompanying drawing is a synoptic diagram of the present invention.
Embodiment:
Below in conjunction with accompanying drawing the present invention is further described:
A kind of method of solid fuel fusion cast glass, it is characterized in that adopting the air conveying method of concentrated phase that the carbonic solid fuels powder is jetted in the glass melter internal combustion, the content of solid-fuelled carbon and protium has determined the size of its calorific value, and ash oontent and fusion point of ash have determined it whether to can be used in the direct burning in the kiln and be used on which the group Fuel lance that distributes along melting furnaces melting end longitudinal axis both sides, in addition, the too high levels of sulphur and vanadium all can be quickened the erosion of basic refractory on the melting furnaces, the sulphur content height also can increase the discharging of sulfurous gas, strengthened the pollution of air, so must select high heating value meticulously, low ash content, low ash smelting point, low-sulfur, the carbonic solid fuels of low vanadium, as coal, kinds such as graphite, fuel feed of the present invention and firing system have adopted the concentrated phase pneumatic conveying method, this method has high solid-gas ratio, transfer rate is low, carry and continue, stable characteristics, because square being directly proportional of air conveying watt consumption and transfer rate, and for pipeline, the wearing and tearing of pipe fitting and valve are directly proportional with the 2-3 power of transfer rate again, thereby the air conveying energy consumption that has not only reduced course of conveying widely of employing concentrated phase, but also significantly reduced pipeline, the wearing and tearing of pipe fitting and valve, this point is for glass works's continuous production more than 5 years, the reality of not having turn(a)round during this period has the meaning of particularly important, the major measure that realizes above-mentioned concentrated phase pneumatic conveying method is: be provided with several solid pulverized fuel spray gun 2 in the glass melter stove 1, the glass melter stove is provided with fuel filler bin 3 outward, winding-up jar 4, fluidisation device 5 and air reservoir 6, winding-up jar 4 is provided with pressure type LOAD CELLS 7, winding-up jars 4 is connected with fluidisation device 5,3 outlets of fuel filler bin are connected with winding-up jar 4 imports through material guiding pipe, winding-up jars 4 outlets through conduit and fuel filler bin 3 inlet mouths be connected, air reservoir 6 is connected with fluidisation device 5 with winding-up jars 4 respectively through airway, 5 outlets of fluidisation device are connected with air compensation regulator 8 imports through conduit, air compensation regulator 8 is connected with air reservoir 6 through airway, air compensation regulator 8 outlets are connected with 9 imports of pulverized fuel divider through conduit, the pulverized fuel divider is provided with some outlets, the outlet of pulverized fuel divider is connected with solid, powdery Fuel lance 1 through conduit, solid, powdery Fuel lance 1 is connected with air reservoir 6 through airway, the form of winding-up jar employing aggregative fluidization jar, fluidizing agent flows in the jar through diffuse metal web plate and gas divider, guarantee that with this jar interior fluidized bed airflow is evenly distributed, improve the aggregative fluidization effect of solid, powdery fuel, thereby make that gas-solid two-phase thorough mixing is even, streaming tank has also adopted the mode of single tube top discharge simultaneously, more than two guaranteed that pulverized fuel carries continuously, stable and even, accurately regulate the interior pulverized fuel weight time differential value of winding-up jar (dw/dt) by adjusting blowing tank pressure and the method for regulating pulverized fuel air compensation regulator flow of air supply size.This has just accurately regulated the weight rate that is sent to the fuel of corresponding port on the glass melter by winding-up jar outlet pipe, be input to heat in the kiln by each port with the constant unit time, thereby stablized the temperature schedule of whole glass melter, guaranteed the quality of the process of founding, the fuel powder that comes out from pulverized fuel aggregative fluidization jar is to deliver to after dividing equally through the pulverized fuel divider on each spray gun of same port, and the length of flame of spray gun ejection is to regulate by the size that the compressed air require on the spray gun is delivered on another road.
