Title:
RECOVERY PLANT OF WASTE HEAT
Document Type and Number:
Japanese Patent JPS5820913
Kind Code:
A
Abstract:
PURPOSE:To keep output constant always and to maintain waste heat recovery efficiency favourably, by installing a heat accumulator upstream exhaust gas of a vaporizer, in a waste heat recovery plant wherein a low boiling point medium is heated and vaporized by waste heat gas. CONSTITUTION:A low boiling point medium is boiled and evaporated by a vaporizer 1 through a preheater 2, power is recovered by a turbine 3 and the medium is returned to the preheater 2 through condenser 5 and a medium pump 6. Exhaust gas is supplied to a heat accumulator 20 and is led to the vaporizer 1 and the preheater 2. A heat accumulating material having a melting point at about indentical temperature with that for a rated design exhaust gas is applied to the heat accumulator 20. The heat accumulator 20 absorbs variation of a temperature of the exhaust gas instantaneously for adjustment to a fixed temperature, then output can be kept constant always. Waste heat recovery efficiency can be made favourable in this manner.
