Boiler room, as one of the critical components in building and industrial installations plays a key role in supplying heat and hot water. Considering the
Heating is one of the fundamental needs in all buildings. In many cold regions, central heating systems are of great importance for providing the necessary
For the combustion of fuel oil, its viscosity must be between 12 and 20 centistokes when entering the burner, and in no case should it exceed 20 centistokes. This way, proper fuel injection and distribution of fuel droplets are ensured. Considering the quality of crude oil available in the market, it is necessary to carefully measure and control the viscosity changes of this fuel with temperature. Furthermore, it is necessary to keep the temperature changes of the heated fuel oil as low as possible to achieve a flame with a uniform behavior and a stable shape.
The use of liquid fuel as a burner fuel can be divided into the following steps:
For appropriate spraying and combustion of fuel oil, it is necessary to reduce its viscosity sufficiently. Viscosity is a variable quantity and decreases with increasing fluid temperature. For instance, the appropriate viscosity for fuel oil combustion in high-energy burners is 5-10 cSt. Reduction in viscosity occurs for fuel with an initial viscosity of 180 to 380 centistokes at a temperature of 100 to 140 degrees Celsius. Since fuel oil sometimes includes impurities and foreign materials, it is necessary to maintain and repair the combustion equipment that works with this fuel type carefully and continuously. Due to the importance of this part of the production line, the main equipment of the combustion system is usually considered dual (including a coarse filter to protect the fuel pump, fuel pump, heat exchangers for fuel preheating, fine filters to protect the nozzle fuel injector). If one fails, the other will continue to work and prevent the complete stop of the production process.
Heat is transferred to all parts of the liquid fuel line (including the heat exchanger of the fuel preparation part for entering the burner, pipelines, and fuel exit from the storage tank), which can be done by water vapor, oil bath, electric current, and Radiation from the flame.
Using water vapor is the most common method of heat transfer to fuel oil for preheating. The following methods can be used to prepare steam:
The significant defects of heating fuel oil with steam are included:
It is worth bearing in mind that in using the boiler burners, using part of the steam or hot water produced by the boiler to preheat the fuel oil is not associated with the mentioned problems and is a suitable method.
PACKMAN Company was established in February, 1975. The company has started its activity in the field of producing High-Pressure Vessels such as Hot-Water Boilers, Steam Boilers, Pool Coil Tanks, Softeners and Heat Exchangers since 1984.
