Abstract
An exhaust gas recycling control system includes a combination device, having inlet and exhaust ends. The exhaust end is connected to the inlet end by a recycling tube which has a control valve to control an open or closed state. An oxygen sensor mounted detects oxygen content in an exhaust gas and convert the oxygen content detected signal into a voltage signal sent to a controller. The controller controls the control valve to open or close. When the oxygen content of the exhaust gas is higher than a threshold, the control valve opens and a high oxygen content of exhaust gas flows through the recycling tube to the inlet end.
Claims7
An exhaust gas recycling control system of combustion device, comprising:
- a combustion device having an inlet end and an exhaust end;
- an air conditioning unit arranged before the inlet end to adjust the supply of cold air;
- wherein the exhaust end is connected with a recycling tube to the inlet end, and the recycling tube includes a control valve thereon to control the recycling tube being in an opened or closed state;
- an oxygen sensor mounted on the exhaust end or the recycling tube to detect an oxygen content in an exhaust gas and convert an oxygen content detected signal into a voltage signal being sent to a controller;
- and
- the controller has a computer processing capability to receive the signal of the oxygen sensor as a control of the control valve being in the opened or closed state;
- when the oxygen content in the exhaust gas is higher than a set value of the controller, the control valve opens and a high oxygen content of exhaust gas flows through the recycling tube to the inlet end to be reuse.
