If the hot oil pump of the fully automatic thermal oil heater is suddenly damaged and stops working during the operation, the boiler circulation will be blocked. If the fuel is still burning to make the oil temperature keep rising, it will cause the coking of the hot medium oil which is easy to cause a fire. If the fully automatic thermal oil heater catches fire due to the power cut during the operation, the boiler operator should quickly put out the fire in the furnace to stop the fuel from burning, and blow a large amount of cold air into the furnace to lower the temperature.
The hot medium oil of the thermal oil heater should be tested regularly to measure and analyze the physical and chemical indicators such as the residual carbon, acid value, viscosity, flash point, melting point and so on, so as to know the quality changes in time and analyze the reasons for the changes. When the acid value exceeds 0.5mgKOH/g, the viscosity change reaches 15%, the flash point change reaches 20%, and the residual carbon (mass fraction) reaches 1.5%, it indicates that the performance of the hot medium oil has changed. Therefore, the user needs to regularly add the new heat carrier when using the hot medium oil to keep the residual carbon in the system stable.
The flue gas first enters the cyclone dust collector which acts as a primary dust collector to make the large dust particles in the flue gas settle down. The cyclone dust collector is a dust removal device which uses the centrifugal force generated by the cyclone flow to separate the dust particles from the air flow. Afterwards, the flue gas enters the wet scrubber dust collector which is a circular-type cylinder. The circulating water enters the dust collector from the upper overflow tank to form a uniform water film on the inner wall of the dust collector. The flue gas is induced tangentially or spirally from the lower part of the cylinder and rotates in the cylinder. Under the influence of the centrifugal force, the dust particles are separated from the flue gas and then the flue gas is also spirally led out from the top of the cylinder. The dust particles are thrown to the water film, transferred to the bottom and finally discharged from the dust port.
The high heat transfer of the boiler requires good medium. With the improvement of boiler in the production technology and intelligenlization, gas-fired boilers have more strict requirements for boiler operation medium in order to improve the boiler operating performance, reduce boiler failures and costs.
Thermal oil heaters have the characteristics of low pressure and high temperature. They adopt the special manufacturing technology and are equipped with tailor-made flue gas waste heat recovery systems, so they are energy-efficient with higher thermal efficiency than similar products on the market. They also have a high level of automation.
Due to the development of boiler technology and relevant policies, gas-fired boilers using eco-friendly fuels are often applied for heating. For thermal power companies, cost is the most important issue.
The thermal oil heater, also called the organic heat carrier boiler, is a kind of once-through boiler developed based on the forced circulation design concept. With gas, oil or coal as the fuel and heat conducting oil as the medium, the thermal oil heater adopts the thermal oil pump to force the medium conducting the circulation in the liquid phase. The medium transfers the heat energy to the heating equipment and then returns to the furnace for being reheated. The thermal oil heater has the advantages of high-temperature and low-pressure heating and precise control of the medium.
Gas-fired hot water boilers require high-quality water to improve the boiler performance and extend the service life. If the boiler uses the tap water of water which contains a lot of impurities, magnesium and calcium ions in the water will form white precipitates when the water is heated at high temperatures, which can cause the scaling problem to reduce the heat transfer efficiency of the boiler and bring hidden dangers of the boiler safety.
