FIELD: technological processes.
SUBSTANCE: method for production of high pressure steam during fermentation of synthesis gas involves bringing in contact of hot synthesis gas with a temperature higher than 760°C (1400 °F) with cooled synthesis gas with a temperature from 177 °C to 232 °C (350 °F-450 °F), herewith the cooled synthesis gas is mixed with the hot synthesis gas in a ratio from 0.1 to 20 to produce in the inlet orifice of the waste heat recovery boiler a preliminary cooled synthesis gas with the temperature of 760 °C (1400 °F) or less, and supply of the preliminary cooled synthesis gas in the waste heat recovery boiler producing a high pressure steam and the cooled synthesis gas.
EFFECT: invention provides high-efficiency production of high pressure steam during fermentation of synthesis gas.
