What are the Impacts Of Extreme Cold Weather On Waste-To-Energy?

Impact of Extreme Cold Weather on Waste-to-Energy

In northern China, the extremely cold weather in winter poses a huge challenge to the operation of waste incineration power generation projects. Low temperatures not only affect the normal operation of equipment, but may also make it difficult to achieve emission standards, which in turn affects the economic benefits and environmental protection goals of the project. Therefore, countermeasures against extremely cold weather are particularly critical. This article will explore in depth the response strategies of northern waste incineration power generation projects in extremely cold weather from multiple perspectives.

Equipment embrittlement

Low temperature can cause equipment to become brittle and crack, forcing the unit to be shut down for maintenance, causing unnecessary economic losses to the project.

Reduced waste incineration efficiency

Under low temperature conditions, the evaporation rate of water in garbage slows down. After entering the grate, the garbage becomes a thawing stage instead of a drying stage. Under the same mechanical load of the grate, the grate drying section length is increased, the combustion point of the grate is pushed back, the normal combustion and ember burning time of the garbage is reduced, the garbage is not fully burned, the heat storage in the furnace is low, and the thermal efficiency of the entire incineration process is reduced.

Slag discharge machine is blocked

The garbage is not fully dried, resulting in an increase in water content. The drying time is prolonged when it enters the grate furnace for combustion, and the combustion process is pushed back, shortening the time of the combustion end and the burnout stage, resulting in incomplete combustion of the garbage, which is prone to produce raw slag and block the slag discharger.
