FUEL-AIR MIXTURE SUPPLY SYSTEM, AND BIOGAS POWER GENERATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a fuel-air mixture supply system that does not limit the ratio of a low-heating fuel gas to a high-heating fuel gas.

SOLUTION: The fuel-air mixture supply system 3 includes: a main fuel channel 8 which introduces the low-heating fuel gas to a mixer 6 via a main fuel control valve 7; a combustion air channel 13 which supplies combustion air to the mixer 6 via an air control valve 12; a diluted air channel 11 which communicates to the main fuel channel 8 on the upstream of the main fuel control valve 7 and supplies air to the main fuel channel 8 using pressure difference between itself and the main fuel channel 8; an auxiliary fuel channel 10 which communicates to the main fuel channel 8 on the upstream of the main fuel control valve 7 and supplies the high-heating fuel gas via an auxiliary fuel control valve 9; and an introduction channel 14 for supplying a mixture mixed in the mixer 6 to a combustion device 4.
