Title:
塊状の被焼成物を再生式竪炉内で焼成する方法
Document Type and Number:
Japanese Patent JP4662927
Kind Code:
B2
Abstract:
A method for burning lumps of material, in particular limestone, is carried out in a regeneration shaft kiln ( 3 ) with at least two kiln shafts ( 1, 2 ) interconnected by an overflow line ( 19 ) and in which the material to be burned passes through an upper pre-heating zone ( 8 ), a central combustion zone ( 18 ) and a lower cooling zone ( 14 ). Combustion gas with a low calorific value of less than 7.5 megajoules (MJ) per m3 is periodically and alternately supplied to each of the shafts ( 1, 2 ) through burner lances ( 9, 25 ) after being pre-heated by heat exchange with process gas of the combustion process. The combustion gas is pre-heated in a heat exchanger ( 21 ) and/or by means of a surface of the burner lances ( 9, 25 ) which extend through the pre-heating zone ( 8 ), said surface being enlarged to enhance heat exchange.
