Use of Natural Gas in Industrial Facilities
Energy use is mostly encountered in meeting the needs of hot water, superheated water, steam, and hot oil in Industrial Facilities. In addition, a large amount of energy is consumed in the process, in heat treatment and melting furnaces, drying, cooking processes, surface cleaning baths and ambient heating.
Energy, which is the lifeblood of the industry, is met by different types of fuel and electricity. Power plants (boiler rooms, etc.), which are the heart of the facilities, constitute one of the important cost items in terms of both their technical equipment and fuel expenditures.
Hot water and steam are highly needed in many industries, generally in the ceramics, agriculture, food, textile and metallurgy sectors. In the baking ovens used in the soil and ceramic industry; In heat treatment and melting furnaces in the metallurgical industry; In automotive paint drying and surface cleaning baths; Energy consumption in textile drying machines (by burning the fuel directly or indirectly) is intense.
Natural gas can be used as an alternative to all other fuels in the industry, both directly in the process and in power generation in heat plants. The advantages of using natural gas in the process are many due to the reasons arising from both the ease of combustion and the composition of the waste gases.
The advantages of natural gas are innumerable in terms of fuel costs, fuel system costs, combustion efficiency, maintenance cost and convenience.
It is only possible to benefit from the advantages of natural gas by burning the oil burners or burners efficiently. An important criterion for this is the determination and selection of suitable combustion systems. The main variables in the selection are the purpose of use, the back pressure and heat transfer structures in the combustion environments (boiler, process furnace, etc.), combustion efficiency and energy requirement.
Combustion systems can be handled under two main headings.
a) Oil burners and Gas burners
b) Gas Path Equipment
a) Oil burners and Gas burners
Natural gas burners, according to the pressure of the gas they burn;
• Low pressure
• High pressure
They are divided into two as burners. Low pressure burners are used in smaller boilers. Working pressures are between 18-25 mbar. In high pressure ones, the working pressure is between 150-300 mbar.
Combustion and safety systems in gas-fired burners are controlled by a control box called “brain”.
The control box stops the operation of the burner in case of flame out, no ignition or by cutting the gas with the thermostat control. During the first operation of the burner, it performs a pre-purge operation, the duration of which varies up to two minutes, in order to prevent the explosion of gases that may remain in the device from the previous operation. The gas is ignited by means of ignition electrodes, and whether the gas ignites is controlled by photocells sensitive to ultraviolet rays of the flame or flame control units operating with ionization electrodes.
