Abstract

1,113,176. Thermal regenerators. M. BAUDER. 3 Aug., 1965, No. 33126/65. Heading F4K. A pebble type '' regenerative heat exchanger particularly for a gas turbine plant, comprises two chambers 11, 12 for the upwards flow of hot gas and air to be heated respectively, and the free fall of metallic particles (e.g. nickel chrome steel) of substantially uniform size with a small mean diameter (0À007 to 0À038 inches), and conveyers 13, 14 for transporting particles from the bottom of each chamber to the top of the other. A plurality of sloping tubes 25, 26 is arranged at the top of each chamber, each tube being divided internally into upper and lower compartments by a longitudinal perforated partition. Particles are introduced into each lower compartment at the upper end thereof, roll along the compartment and fall into the chamber through apertures in the floors of the comparttnent. Each upper compartment is connected to an air supply via pipe 37A, the pressure of the air thus controlling the flow rate of particles so that the gas (or air) velocity exceeds that of the particles by about 5% and the product of weight flow rate and specific heat is equal for the gas (or air) and the particles. The chambers are shaped so that the ratio of gas velocity to the terminal velocity of the particles in each chamber is substantially constant at any horizontal cross-section.
