1T gas aluminum melting furnace for sale
1T gas aluminum melting furnace for sale, this article brings customers accurate science popularization of combustible gases, especially cold clean coal gas, which is superior to liquid fuel and solid fuel in many ways. Therefore, gas fuel has been widely used; even if the price per unit of heat is slightly higher than that of other fuels, gas fuel is used as much as possible.
Natural gas As the name suggests, this gas fuel is neither artificially produced nor chemically synthesized, but is directly used after being developed from underground. The calorific value (referring to high calorific value) of various natural gases in the United States is in the range of 31500~13400 kcal/m³. Since the amount of air required for the combustion of a unit volume of gas fuel is roughly proportional to the calorific value of the gas fuel, the amount of air required for various natural gases varies greatly.
The composition of natural gas is just an average value.
However, most of the natural gas delivered to users via pipelines conforms to this average value, because Texas natural gas is now sent far and wide and mixed with “nearby” natural gas to supply users. Although this mixing cannot eliminate the difference in composition, it can effectively make the difference very small.
Natural gas, which has a high calorific value, contains natural (gaseous) gasoline, butane, and propane.
After these components are extracted, the remaining gas is called “dry gas.” However, this name does not mean that the gas does not contain water vapor.
Natural gas is now the most ideal fuel for industrial furnaces. Natural gas pipelines have been laid in industrial areas in almost every state in the United States. Natural gas generally has a high calorific value, so it can be transported in smaller pipelines. Natural gas is very clean and generally does not contain sulfur, with very few exceptions. Intermittent use of natural gas does not require backup facilities because the earth is an artificial gas tank. Artificial gas storage here means that natural gas from distant gas wells is pressed into nearby abandoned wells that have been exhausted in the summer. Therefore, in areas near abandoned wells, the supply to industrial users is rarely interrupted.
In areas far away from production wells and storage wells, backup facilities for burning propane or light oil are needed.
Natural gas is almost entirely composed of various hydrocarbons, so it can produce a bright flame when needed. Natural gas has a high hydrocarbon content and cannot be preheated in a regenerator or heat exchanger because hydrocarbons will produce carbon black when cracked at high temperatures and block the channels. In addition, the amount of heat saved by preheating natural gas is negligible because the weight of natural gas is less than one-fifteenth of the total weight of the fuel-air mixture. A mixed gas composed of a small amount of natural gas and a large amount of blast furnace gas does not form carbon black when preheated, probably because the free carbon will combine with the CO2 in the blast furnace gas.
