Low concentration gas source conditions: low concentration gas transport pressure 5-15 kPa, pressure change rate less than 1 kPa/min, change rate less than 5%/min; impurity particle size less than 5 micron, impurity content less than 30 mg/Nm3, moisture content less than 40 mg/Nm3, free water, gas temperature less than 40 C, sulfur content less than 20 mg/Nm3.
3. Technical characteristics of products:
(1) Suitable for the gas concentration range of 8%-30%, suitable for the characteristics of large shaking of coal-bed methane source, can ensure the constant output power of the unit.
(2) In the low concentration gas transportation system, measures such as flame cold wall calming and fire suppression, wet water seal and wet water mist accompanying transportation are adopted to ensure the safety of transportation, and mixed fine water mist can be used to accompany pipelines with long transportation intervals.
(3) The real-time control of the optimum air ratio and the optimum incineration advance angle of the gas engine can be achieved by using the technology of electronic control mixer and closed-loop automatic control. The optimum control of the incineration advance angle can be achieved by detonation monitoring, so that the engine can operate in the optimum condition, and the engine can avoid deflagration, intake pipe backfire and exhaust pipe firing. And so on.
(4) The incineration system produced by ALTRONIC Company of the United States is selected to obtain high incineration energy and accurate incineration time to ensure the safety and reliability of incineration.
(5) The low speed of the generator set reduces engine wear, prolongs the service life of the components and reduces the storage of spare parts;
(6) Double-layer water-cooled exhaust pipe structure is selected, with low exhaust temperature, abundant incineration and uniform exhaust temperature of each cylinder.
(7) Coal-bed methane engine has developed an intelligent management system for gas engine, which can ensure the safe and efficient operation of the gas engine and complete the remote monitoring of the gas engine group.
