As in high-heat furnaces is transferred mainly by radiation heated metal, and formed during combustion of natural gas gaseous products have a low degree of blackness, the rational to burn natural gas under such conditions is achieved when the highest temperature of combustion products, and then in high-temperature furnace to enter the field of hydrocarbons and reduce the rate of airflow in the combustion products to the required for the intensification of heat transfer units. This somewhat decreases the temperature of hot gas, but formed when the decomposition of hydrocarbon particles of carbon to increase the degree of blackness and the emissivity of combustion products, as evidenced by the results of the study. Decomposition of hydrocarbons of natural gas almost finished at that temperature (1473 K), which is lower than the temperature of combustion products in high temperature furnaces. With the expansion of hot combustion products of hydrocarbons are enriched not only illuminated the particles of carbon and hydrogen, and carbon and hydrogen have a high recovery properties, increasing with increasing temperature. Consequently, the intensification of heat transfer in high temperature furnaces can be achieved not only through higher emissivity of hot combustion products in connection with the formation of the dispersed phase of solid particles of carbon, but also due to the fact that with decreasing oxidative properties of the products of combustion will be less than the thickness of heat-insulating oxide film on the surface of heated metal. To reduce the flow of heat in an oven for heating and decomposition of hydrocarbons, their rational pre-heat prior to the making of products of combustion. This helps to maintain the high temperature combustion products and increase their emissivity. The higher value of FF is achieved, taking into account the temperature in the furnace to maintain the technological process and the higher temperature pre-heating of hydrocarbons, the greater the amount of hydrocarbons can be injected to highlighting the products of combustion and the intensity becomes izluchatednaya ability furnace atmosphere. Hot gases should be turbulizirovat and zasvechivat hydrocarbon sprays in areas where intensification of heat transfer. After participating in the heat should be dozhigat waste gas, increasing air flow rate to values higher than 1, and produce waste heat of these gases. Outlined the way the combustion of natural gas allows you to control the combustion process, luminosity and composition of combustion products, the intensification of heat transfer in high temperature furnaces to process furnaces economically. This method has been tested for effectiveness in the Crude Iron furnaces - gas cupola. With regard to the processes of smelting iron with gaseous fuels has been invented, patented in many foreign countries, the method of melting iron in a gas cupola, only difference is that in high-temperature furnace enters the field of hydrocarbons. To increase the resistance of linings developed a way to get iron in a gas cupola comprising termokreking of natural gas (hydrocarbons), is different in that the cold natural gas to the hot surface of refractory lining the camera overheating. When the gas in the cupola of hot air to raise the temperature of the metal nozzle of the system are encouraged to supply gas to pass through the reservoir of hot air.
