The coal-fired boiler has low fuel costs and high calorific value, which is a kind of important auxiliary heating equipment in the production-oriented enterprises. However, the coking on the furnace wall is common in the operation of the coal-fired boiler.
The thermal oil heater, also called organic heat carrier boiler, provides heat energy for production by heating the heat medium oil. It can realize the high-temperature and low-pressure heating without constant water supply. What are the characteristics of the thermal oil heater?
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.
The biomass-fired boiler is a kind of equipment that uses the combustion of renewable energy biomass to provide heat energy for the boiler. The biomass-fired boilers are widely used especially by the enterprises located in the areas with abundant biomass fuel.
What are the reasons for the low efficiency of dust collector of the biomass-fired boiler? They are nature of dust, quality of bag and velocity of filtering.
Once the flameout of gas-fired or oil-fired boiler is confirmed, the boiler should be shut down for inspection and maintenance in time according to the operating regulations. Only after the inspection and test are completed, the boiler can continue to be used.
When using the thermal oil heater, users often add some auxiliary device to the boiler for more stable and safe operation. This is an introduction about the installation and using tips of thermal oil heater's auxiliary device.
If the boiler gives overpressure indicator which affects boiler's safe operation, depressurization measures should be taken. However, please pay attention that depressurization can not be too fast. After the overpressure problem of steam boiler is solved, we should check the internal and external parts of boiler to ensure that everything is going well.
