Furnace equipment manufacturers

Furnace equipment users and industrial furnace technicians are not interested in the geological history of fuels or other heat sources. They are interested in the properties, use value and relative prices of various fuels.

Furnace equipment

The main properties of various commonly used gaseous, liquid and solid fuels are listed in the table. Because the composition of fuels is always changing, the values ​​in the table are some average values. This chapter will also elaborate on the properties and use value of various fuels.

An important property of fuel is the adiabatic flame temperature, that is, the temperature that the fuel should reach when it is burned in an adiabatic combustion chamber at a constant pressure with a theoretical amount of air at room temperature. Adiabatic flame temperature of different fuels under different conditions. In calculating the temperatures in these figures, the cooling effect caused by pyrolysis was not considered.

For industrial furnaces, natural gas is now the most ideal fuel. Natural gas pipelines have been laid in industrial areas in almost every state in the United States. Generally, natural gas 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 compressed and sent to nearby abandoned wells that have been exhausted in summer. Therefore, in areas near abandoned wells, gas supply to industrial users is rarely interrupted. In areas far away from production wells and storage wells, backup facilities burning propane or light oil are required.
