The coal is usually smashed to be the pulverized coal for boiler combustion. This is an introduction to the causes and treatment methods for the extinguishment of the pulverized coal fired boiler.
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.
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.
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.
The industrial pulverized coal fired boiler is a new type of industrial coal-fired boiler focusing on pulverized coal combustion technology. The impurities are well removed when the grinding fitness of pulverized coal reaches 200 mesh. The pulverized coal is easy to be ignited and has few ash contents, which can enhance the complete combustion rate and reduce the burden of dust removal.
In general, gas-fired boiler uses natural gas to heat water in order to provide heat source for underfloor heating and heating radiator, while condensing gas-fired uses condensation technology to recycle the thermal energy from the exhaust gas.
Industrial boilers will produce wastes that needs to be treated during the use process, which is what we mentioned of boiler blowdown. What are the methods for boiler blowdown?
1. Regular blowdown
1) The time interval and quantity of discharge depend on the test results of boiler water. It usually do not exceed 5% of the water supply.
2) When the regular blowdown is being made under high load of the boiler, the blowdown of the water-cooled wall header is generally not required to avoid affecting the normal water circulation of the water-cooled wall and forming a tube explosion incident.
2. Continuous blowdown
The amount of blowdown shall be determined according to the test results of the boiler water, and shall be completed by adjusting the needle-shaped angle of the blowdown tube.
