Abstract

The invention discloses a uniform-temperature superheater for a waste incineration boiler and a superheated steam heating method. The uniform-temperature superheater comprises a plurality of unit tube groups, wherein each unit tube group comprises an inlet mixer, an outlet mixer and a plurality of U-shaped superheating tubes which are connected between the inlet mixer and the outlet mixer in parallel; and the plurality of unit tube groups are sequentially arrayed, wherein the outlet mixer of the previous unit tube group is connected with the inlet mixer of the next unit tube group through a plurality of connection tubes which are connected in parallel. The uniform-temperature superheater disclosed by the invention is convenient to manufacture, short in tube pass, capable of improving the uniformity of the flow rate and the flow speed of steam in each section of tube and enabling the temperature of each section of tube to be balanced, and capable of preventing that the temperatures of the tubes are too high to accelerate corrosion to cause tube burst, thus benefiting to long-time stable running of the boiler.

Description

technical field

[0001] The invention relates to a superheater and a superheated steam heating method, in particular to a uniform temperature superheater and a superheated steam heating method for a garbage incineration boiler. Background technique

[0002] In the 21st century, with the improvement of people's living standards, the amount of garbage generated is also increasing. Many large cities have formed a dilemma surrounded by garbage, and the problem of garbage treatment and disposal has been placed before us. Incineration power generation is the most effective way to deal with urban domestic waste. It can not only achieve the purpose of reducing the volume to the greatest extent, but also the flue gas can meet the environmental protection standards stipulated by the state after treatment, so as not to cause secondary pollution. The heat energy released by waste incineration It can also be used to reduce the use of coal and reduce carbon emissions. Waste incineration p...
