Shipping information recommendation person
On September 25, "JiangLong", China's first methanol powered ship, was commissioned in Jianglong Shipbuilding Co.,Ltd. (hereinafter referred to as Jianglong Shipbuilding).More than 2,000 kilometers away, professor Yao Chunde, deputy director of the state key laboratory of combustion of internal combustion engines at Tianjin University, pays close attention to the debugging feedback.Yao Chunde told reportersthat the first successful application of the "methanol/diesel dual combustion technology" developed by several scientific researchers in the laboratory in the field of shipbuilding can reduce the emission of carbon smoke by 50-70%, marking a key step for domestic vessels to use "methanol" fuel.
Thousands of miles "marriage" ,a boat lead
The green"JiangLong" is about 40 meters long, 8 meters wide, 2.7 meters deep and 172 tons dead weight.In the two months since the launch, the crew has been carrying out parameter adjustment before the trial, preparing for the trial in the best condition."JiangLong" is a test ship jointly developed by Jianglong Shipbuilding, Guangxi Yuchai Machinery CO., LTD., and other enterprises and the state key laboratory of internal combustion engine of Tianjin university. It is the first methanol fuel-powered ship launched in China with independent intellectual property rights of "methanol/diesel dual combustion technology".Experimental data show that under the dual-fuel model, "JiangLong"'s carbon emissions can be reduced by 50 to 70 percent.
At the state key laboratory of internal combustion engine combustion at Tianjin University, a machine identical to"JiangLong"'s power system is running.Yao chunde told reporters that if the test ship in Zhongshan needs to solve the parameter problem, the laboratory can simulate the running state in real time and provide a solution.The main body of this blue engine is a general Marine diesel engine, but with methanol and air mixing device, methanol control unit, methanol fuel supply system and other accessories.Behind the concise solution, is the laboratory more than ten years to live up to the mission of continuous practice of research and development results.Several scientific researchers traveled around the country, collected experimental data under different climate conditions, and then jointly developed the internal combustion engine with Yuchai Company. In practice, they solved a series of practical application problems of methanol as fuel, such as ignition, smoke extraction and parts anti-dissolution.
The reporter saw through the experiment video, the ordinary diesel engine cavity pure diesel intense combustion gives off the flame, and the methanol and diesel dual combustion flame is due to the full combustion of many dim;Outside, black smoke is sprouting from conventional diesel-powered ships, and smoke from methanol-powered ships' exhaust systems is barely visible.
As a fuel, methanol is green and clean, and the dual combustion technology is relatively mature. However, as the national policy has not clearly defined the use of methanol as a power fuel, the research and development achievements in the laboratory "blossom in the wall" but still have not achieved "fragrance outside the wall".In the laboratory of the "old friend"Yuchai Company,Jianglong Shipbuildingt decided to three parties in the field of boat testing.It took three years for the birth of "JiangLong", a key step for domestic vessels to use "methanol" fuel.
Explore the way for Marine energy transformation
In recent years, Chinese energy transformation is deepening, and the pace of clean and low-carbon development is accelerating. Jianglong Shipbuilding is also seeking for power transformation.JianglongShipbuilding deputy general manager Gong Xuehua told reporters that from the perspective of national energy security and environmental protection, the development of clean energy powered boats is the trend.Chinese"sulfur restriction order" has been issued, which puts forward control requirements on the emission of sulfur oxide, particulate matter and nitrogen oxide from ships driving in the sea area.In recent years, Jianglong Shipbuilding will be clear clean energy boat development included in the company's development strategy.In addition to methanol fuel powered boats, we are also carrying out research and development of electric power boats, hydrogen fuel powered boats, wind-solar complementary power boats and other new clean energy powered boats.
"Methanol powered boats have a promising future."Gong Xuehua said, "' lack of oil, gas, rich coal is our country the status quo of energy, and coal methanol synthesis technology has been very mature, Tianjin University of combustion state key laboratory of 'methanol/diesel dual combustion technology has been carried out in areas such as automobile pilot application, this year the state ministry of clear support methanol automobile development, these are for the application of methanol fuel in the field of ship manufacturing industry provides the basis."
From 2016 to 2018, Jianglong Shipbuilding has invested more than 30 million yuan in research and development of clean energy boats, smart boats and high-performance boats for three consecutive years."The concept of green has been throughout our product life cycle."Fang Hongpei introduction, chief technology officer at Jianglong Shipbuilding as the national first batch of "green factory", the enterprise to promote the ecological product design, production process clean, energy utilization efficiency, attach more importance to the recovery of renewable resources direction, through the integrated innovation technology, wind-light complementary, diesel electric propulsion, pure electric electric propulsion, clean energy propulsion and other new energy power technology is applied to the design of the boats built in.
"Early next month, we will send a team to Zhongshan to participate in the final commissioning of the "JiangLong", which is expected to be ready for sea trials soon."Yao chunde said.
At present, methanol has been confirmed as ship fuel in the technical specification document of the international maritime organization, and it is expected that methanol will also be used on ships in China in the future.In Zhongshan,Jianglong Shipbuilding plans to use the"JiangLong" as a mother ship, which will be promoted to customers after trials.
