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.
With the continuous development of boiler manufacturing process and technology, fuel types of boiler have also increased, such as various combustible gases, fuel oil, biomass, coal and so on.
1) Set up the air preheater. One of the most effective measures to improve the thermal efficiency of thermal oil heater is to use an air preheater for heat recovery. 2) Use waste heat boiler for heat recovery. The waste heat boiler uses the waste heat in the flue gas exhausted from the thermal oil heater to heat water or generate steam.
As a kind of essential equipment applied by many enterprises, condensing boiler is widely favored and recommended for its advanced condensation heat transfer technology, intelligent operation mode and high efficiency in the production. Let us talk about the main significances of using condensing boiler from the following three perspectives.
Some kinds of boilers have the problem of energy waste caused by heat loss in the process of steam transmission due to their special structures. To solve this problem, we should properly improve the steam transmission process.
