REGENERATOR CHECKER Russian patent published in 1995 - IPC

FIELD: metallurgy and power engineering where air and other heat-carrying agents must be heated to high temperatures. SUBSTANCE: regenerator checker is made of brick with trapezoidal edges whose large sides are on top for wide side edges and at bottom for narrow ones. Half-difference between bottom and top sides of narrow side edge is 0.1-0.8 of half-difference of top sides of wide and narrow edges of brick and half-difference between top and bottom sides of wide side edge of brick is 0.1-4 half-difference between top sides of wide and narrow side edges greater than half-difference between bottom and top sides of narrow side edge of brick; maximum half-difference between top and bottom sides of wide side edge of brick equals half-difference between top sides of wide and narrow side edges of brick. EFFECT: improved design. 5 dwg
