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.
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.
The biomass-fired steam boiler is used widely and the biomass belongs to the renewable energy with high thermal efficiency which can be applied by many production enterprises.
Gas-fired boilers are widely applied for civil use and in the industry with high thermal efficiency and good eco-friendly performance. What are the precautions for the commissioning of newly installed gas-fired boilers?
