regenerator(redirected from Regenerative heat exchanger)
Also found in: Dictionary, Acronyms, Wikipedia.
in heat engineering, a device used to transfer heat by periodically bringing a heat-transfer agent into contact with the same surfaces of the device.
During contact with a hot heat-transfer agent, the walls of a regenerator are heated, and during contact with a cold heat-transfer agent, the walls are cooled, thereby heating the heat-transfer agent. Regenerators in which the heat-transfer agents are periodically reversed consist of several chambers filled with a checkerwork. Hot flue gases and air or gaseous fuel that are to be heated are introduced alternately into the chambers. In regenerators in which the heat-transfer agents are continuously being reversed, either the checkerwork alternately is brought into the sprinkling zone by the heat-transfer agents or the checkerwork is stationary and the air pipes placed within the gas chamber rotate.
Air is heated to 1000°-1200°C in regenerators in which heat-transfer agents are periodically reversed, while in regenerators in which there is a continuous reversal, air is heated to 400°C. The latter regenerators, however, are significantly more compact and economical.
