Abstract
The utility model relates to a flameless burner. The flameless burner does not adopt the fluidics that the coal gas is injected by high speed air according to volume proportion, and the flameless burner cancels a coal gas zero pressure valve and a coal gas-air mixing device and adopts a simple coal gas-air mixing pipe to replace a complicated coal gas-air proportional mixer. At the same time, an adjusting valve is arranged on a coal gas pipeline to automatically adjust coal gas flow rate. The flameless burner solves the technological problem of charging channel temperature fluctuation because of relatively great gas caloricity fluctuation and achieves the sensitive and exact adjustment and control of the charging channel temperature. The flameless burner has the advantages of simple structure and strong practicability and meets the technique situations of national existing gas fuel, being suitable for the tank furnace charging channel of various products in national glass industry.
Description
The utility model relates to a kind of flameless combustion apparatus, is applied to the glass production field.
Existing flameless combustion apparatus all is to use fluidics, adopts high-speed air ratio injection coal gas by volume, is about to control valve and is contained in automatic adjusting air mass flow on the air duct, thereby make gas flow also be regulated in proportion and control.This matching requirements calorific value of gas fluctuation range is very little, and requires the much coal gas zero-pressure valves that all must pass through of external coal gas pressure be reduced to the zero-pressure state automatically, just can reach the purpose of regulating and controlling the material channel temp.But, because domestic present gaseous fuel situation is difficult to reach the very little requirement of calorific value of gas fluctuation range, simultaneously, the crudy of coal gas zero-pressure valve can not guarantee to make automatically gas pressure to be reduced to the zero-pressure state, thereby influence the gas flow of air ejection, also by certain volume ratio coal gas and air are mixed, therefore with regard to not guaranteeing, must cause and accurately to regulate and to control the material channel temp delicately, directly influence the quality of product.
In order accurately to regulate and control the material channel temp delicately, the utility model provides a kind of improved flameless combustion apparatus.
Flameless combustion apparatus described in the utility model is to utilize gaseous fuel that the glass metal in the material road of various glass melting furnaces is evenly heated by technological requirement, makes the temperature of glass metal reach the special equipment that moulding requires.Flameless combustion is that gas combustion (comprising coal gas, natural gas, liquefied petroleum gas and iso-butane etc.) is mixed in advance with combustion air, there is not square type flame during burning, form high-temp combustion in the brick but chew in several burnings, and burn by these high temperature chew continuously, equably, large-area mode of glass metal being carried out radiation heating.Molding mode and technological requirement according to the structure of glass melting furnace and load size, product are different, will expect to be divided into several zones, and a cover flameless combustion apparatus is set in each temperature province.This device is chewed (8), material road (9) etc. by coal gas compression release valve (1), solenoid valve for gas (2), control valve (3), coal gas spinner flowmeter (4), air robot flowmeter (5), coal gas air mixing device (6), explosion-protection equipment (7), nonflame burning and is formed, it is characterized in that: control valve (3) is contained on the gas piping (as shown in the figure) and regulates gas flow automatically, coal gas air mixing device (6) adopts simple coal gas air mixing tube, replaces complicated coal gas AIR Proportional blender.The utility model is bypassed with the high-speed air fluidics of ratio injection coal gas by volume, cancelled coal gas zero-pressure valve, according to constant at the material channel temp, when fuel gases calorific value changes under the constant process conditions of heat demand, the principle that required combustion-supporting air quantity is also constant substantially, determine the institute's calorific requirement and the air expense of this warm area of material road, the required air quantity of each warm area flameless combustion apparatus is adjusted to maximum by spinner flowmeter, and its fixing weight feed that forms, simultaneously control valve is contained in and regulates gas flow on the gas piping automatically, and adopt the temperature of each warm area of thermocouple measurement material road.
The utility model has solved the technical barrier that influences the fluctuation of material channel temp because of the calorific value of gas fluctuation greatly, has realized accurately regulating and to control the material channel temp delicately.It is simple in structure, is fit to the technology status of domestic existing gaseous fuel, is applicable to the tank furnace material road of domestic glass industry various product, and its practicality is strengthened greatly.
