摘要: Abstract Boiler air pre-heater with multi-stage LHS unit is investigated entransy analysis. Optimum melting temperature match derived. It concluded that optimum decreases alongside flow direction of flue gas. at inlet increases stage number, while outlet decreases. Temperature difference PCMs in two nearby portions the same but number. Entransy dissipation compared unit. normalized not always reduced whole period, due to decrease heat transfer rate SHS However, unit, except single-stage when storage amount constrained. Reduction degree Therefore, favored for recovery waste gas and improvement boiler efficiency.
