The automatic boiler water level controller is mainly composed of hardware and software parts to complete the functions of the control system. The hardware part is mainly composed of the water level detection circuit, drive circuit, water level indication circuit, pressure automatic control simulation, manual control, etc. The software part is mainly composed of the programs written in assembly language.
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.
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.
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 fuel is necessary for the boiler operation. The fuel choice can also affect the overall boiler operating efficiency and the pollution emission of the boiler. What are the differences between the oil-fired boiler and coal-fired boiler?
The slugging for the circulating fluidized bed boiler means that the bubbles in the feed layer converge and grow. When the diameter of the bubbles grows close to the cross section of the bed, the feed layer is divided into several sections to be particle layers with intervals of bubble sections. The particle layers are pushed by bubbles to move upwards to a certain height and then they burst into a large number of small particles that are thrown out of the bed and carried away by bubbles, while the large particles fall down like rain.
