Advantages of thermal industry cluster and application of particle swarm optimization model
2020
This paper first analyzes that the waste heat before the flue gas of thermal
power company enters the desulfurization tower can be heated by the
low-pressure economizer, and then the heated condensate can be incorporated
into the regenerative system, so as to recover the waste heat and improve
the unit efficiency. In this paper, the possible layout scheme of the low
pressure economizer in the thermal system is constructed firstly, and then
the mathematical model of the equivalent enthalpy drop increment of the unit
is established with the water partition coefficient as the independent
variable. Particle swarm optimization and coordinate rotation are used to
optimize the model, and the results show that particle swarm optimization is
more effective in solving the problem. After the low-pressure economizer is
added to the unit, the heat consumption of the whole plant of the unit is
reduced by 61.131, the unit efficiency is increased by 0.783%, and the coal
consumption of the whole plant is reduced by 2.293. Finally, from the
perspective of industrial agglomeration, industrial diversification and
economic resilience, this paper analyzes the advantages of diversified
agglomeration of thermal power companies.
