METHOD OF RECUPERATION OF ENERGY FROM HOT GAS |
摘要 |
FIELD: recuperation of energy from hot gas. ^ SUBSTANCE: proposed method is used for recuperation of energy from hot gas having temperature above 650°C and absolute pressure above 1.7 bar; gas contains non-solidified compounds of alkali metals and particles. Proposed method includes the following stages: cooling gas to temperature below 550°C with the aid of shell-and-tube heat exchanger where hot gas is passed via inter-tube space and cooling water is passed via space inside tubes where steam is formed from which steam energy is recuperated; particles of gas are separated by means of one or more centrifugal separating units arranged in succession to obtain content of dust below 400 mg/Nm3; gas is expanded in expansion machine for recuperation of energy. ^ EFFECT: enhanced efficiency of recuperation. ^ 16 cl, 1 dwg |
