The safety valve of the boiler refers to the valve on the top of the boiler near the boiler control room. The function of the safety valve is to be opened automatically to exhaust the steam and restore the pressure when the boiler pressure exceeds the specified valve, so as to ensure the safety of boiler pressure-bearing components and steam turbines.
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.
Biomass-fired boilers can burn many fuel types, but they all belong to biomass energy, such as corn stalks, wheat straws, straws, peanut shells, corn cobs, cotton stalks, soybean stalks, weeds, branches, leaves, sawdust, bark and other solid waste of wood or furniture factories.
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 gas-fired boiler has the wonderful energy-saving effect and environmental protection performance. The energy-saving effect of the gas-fired boiler is realized by many boiler parts.
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 natural gas fired boilers occupy a large proportion of boilers for the industrial and civil uses. They have low energy consumption and can reach the environmental protection standards.
