BIOGAS ENGINE SYSTEM
Document Type and Number:
Japanese Patent JP2023175435
Kind Code:
A
Abstract:
To provide a biogas engine system which can control the amount of generation of air bubbles.SOLUTION: A biogas engine system 1 comprises: a biogas generation part 2 for generating a biogas; a biogas engine 3 for combusting the biogas; a waste heat collection device 4 for heating the biogas generation part 2 by the waste heat of the biogas engine 3, a temperature sensor 5 for detecting a temperature of the biogas generation part 2; a bubble amount sensor 6 for detecting a bubble amount of the biogas generation part 2, and a control unit 7 for controlling the waste heat collection device 4 according to the temperature and the bubble amount. When the temperature of the biogas generation part 2 is equal to or higher than a prescribed value and/or the bubble amount of the biogas generation part 2 is equal to or larger than a prescribed value, the control unit 7 can switch to a cooling mode for cooling the biogas generation part 2, and when the temperature of the biogas generation part 2 is lower than the prescribed value and the bubble amount of the biogas generation part 2 is smaller than the prescribed value, the control unit 7 can switch to a heating mode for heating the biogas generation part 2.SELECTED DRAWING: Figure 1
