The invention relates to the technical field of gas engines, in particular to a gas supply system for low-concentration gas engines. The low-concentration gas engine gas supply system includes a main pipeline, a delivery pipeline, a mixer, and at least one delivery branch; the inlet of the main pipeline is used to receive low-concentration gas, and the inlet of the delivery pipeline and the inlet of the delivery branch are respectively connected to the main pipeline. The outlet of the conveying branch and the outlet of the conveying branch are connected to the inlet of the mixer, and the outlet of the mixer is used to connect with the cylinder of the engine. It can ensure that the engine can work stably even when the gas source has a low concentration of 8%-20%.
Description
technical field [0001] The invention relates to the technical field of gas engines, in particular to a gas supply system for low-concentration gas engines. Background technique [0002] Existing coal mines have widely used gas generators to generate electricity. However, the current gas generator sets have strict requirements on the gas source, requiring stable gas concentration and pressure. The existing low-concentration gas engines on the market must operate at a concentration of about 20%. The problem of actual storage is that there are long-term slow changes of gas concentration and transient sudden changes, and the range of concentration changes is relatively wide. [0003] When the concentration of the gas source changes sharply from 8% to 20%, that is, when the gas source concentration of the gas is at a low concentration of 8% to 20%, it is difficult to start the generator set, and even if it is started, the speed is unstable and the power will be reduced. , It is...
