Daewoo Shipbuilding awarded Wärtsilä inert gas program contract

It is reported that a few days ago, Daewoo Shipbuilding Co., Ltd. recently awarded Wärtsilä a contract to supply inert gas generators and gas burners to 17 LNG carriers under construction. The contract is expected to be delivered to Daewoo Shipbuilding in the third quarter of 2016.

According to the news, Wärtsilä signed the above supply contract in June and September 2015. The operators of these new ships are from Singapore, Greece, South Korea, Cyprus and Canada.

According to reports, the combined inert gas generator and gas burner are jointly developed by Wärtsilä and Daewoo Shipbuilding. The maximum gas production capacity is 3800 kg / h, which is enough to meet the needs of the largest LNG carrier in the shipping industry.

It is understood that the ship uses the existing Wärtsilä Moss inert gas generator to burn the evaporated LNG gas, which reduces the traditional gas burning device and greatly saves expenses and operating costs.

Nox Sensor For MAN

In practical application,the probe is installed in the tail gas pipeline of the automobile,and the concentration of the tail gas will be fed back to the electronic control unit by theceramic chip in the form of voltage.The heating temperature of the sensor probe is controlled by the electronic control unit.After a series of signal conditioning,the concentration of Nox and oxygen in the pump is finally determined.The electronic control unit communicates with the vehicle control center(ECU) through the CAN,and transmits the measured gas values to the vehicle control center(EUC )in real time,which provides the basisfor SCR injection quantity,so as to reduce the emission of NOx.
Different types of nitrogen oxygen sensor are suitable for different models, and the nitrogen oxide sensor in this category are all suitable for MAN.
