Problems solved by technology
[0005] (2) The service life of the atomizer, that is, the burner nozzle is short
The presence of coal particles in the CWS leads to wear of the nozzles, which is aggravated at high capacity and high loads, leading to shortened life of the burner nozzles
Therefore, the burner nozzle must be replaced regularly, which increases the material cost and maintenance cost of operation, and reduces the continuity of operation
[0006] (3) There is a waste of space occupied by the site and infrastructure; there is a waste of personnel in staffing

Embodiment Construction
[0025] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following technical solutions in the present invention are clearly and completely described. Obviously, the described embodiments are some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0026] The principle of the chain grate furnace is relatively backward. The coal is burned on the chain grate furnace after being watered. The coal is not fully burned and the temperature control is not good. The coal-water slurry furnace is to use a pressure pump to pressurize the 50% coal-water slurry through the pipeline, spray the water-coal slurry spray gun into the furnace for combustion, and use more coal to evaporate the water containing 50% of the water. ...

Description
technical field [0001] The invention belongs to the technical field of kinetic energy and thermal engineering, and in particular relates to a spray drying tower system. Background technique [0002] Coal-water slurry furnace refers to a boiler that uses coal-water slurry as fuel. Coal-water slurry furnace is a liquid prepared by mixing about 70% coal powder, about 30% water and a small amount of chemicals. It can be pumped, atomized, stored and transported like oil, and can be directly used in various The combustion of boilers and coal stoves. It has changed the traditional way of burning coal, showing great advantages in environmental protection and energy saving. Especially in recent years, after adopting the technical route of recycling waste, the environmentally friendly coal-water slurry has been successfully developed, which can greatly improve the environmental protection benefits of coal-water slurry without increasing costs. With the guarantee of my country's abu...
