Coal-fired boilers supplying steam to chemical plants are all "off the job"
On May 6, the 12 sets of waste heat recovery boiler of Hubei Xingfa Group was formally put into operation at Liucaopo Chemical Factory, and the last coal-fired boiler of the plant was also decommissioned. So far, the group's world's first phosphorous chemical production waste heat recovery technology has been fully promoted. It has fully realized the use of recovered waste heat instead of coal-fired boiler self-produced steam, and can save energy up to 100,000 tons of standard coal.
With the application of waste heat recovery technology for phosphorus chemical production, the Hing Fat Group has shut down all coal-fired boilers that have been in use for nearly 20 years, and can reduce the use of raw coal by 163.36 million tons, equivalent to 105.01 million tons of standard coal; the annual reduction in carbon dioxide emission can reach 367,300 tons. There are 2614 tons of sulfur dioxide, 980 tons of dust and 40.84 tons of coal cinder. At the same time, the company can save nearly 5 million kWh of boiler electricity annually and save 3.8665 million tons of water. This technology has applied for a national patent.
This technology allows companies to complete energy-saving emission reduction targets 4 years in advance, creating considerable economic and environmental benefits. Not long ago, Hing Fat Group replaced waste heat with 200,000 tons of greenhouse gas carbon dioxide, which was used to reduce emissions from coal-fired boilers, and sold it to developed countries, the Kyoto Protocol, in the form of the CDM (United Nations Clean Development Mechanism). 7.6 million euros.
It is understood that waste heat utilization is the most representative project for Xingfa Group to implement energy-saving and emission reduction. Previously, on the one hand, the Hing Fat Group required more than 100,000 tons of coal-burning and nearly 500 million kilowatt-hours of electricity to produce phosphorus chemical products each year. At the same time, it also produced solid waste such as sulfur dioxide, smoke and dust and other waste gases and coal slag; on the other hand, it used thousands. Tens of thousands of tons of cooling water will discharge waste heat and waste tropics from phosphorus chemical production to the environment. In the face of this contradiction, the company organized its forces in 2005 to tackle technological problems. In less than a year, it has pioneered the development of a waste heat recovery device for phosphoric acid, which uses phosphorus chemical waste heat instead of burning coal to supply steam to chemical plants. It has also overcome key technologies such as high-efficiency heat transfer, equipment corrosion, and automatic control during the recovery of waste heat. They successively learned the sulfuric acid waste heat recovery technology, space heat pipe heat dissipation technology, heat pump technology and advanced pinch analysis theory, and implemented a one-step hot phosphoric acid method to change two-step recovery of thermal energy production steam, recovery of phosphate polymerization exhaust gas residual heat production steam. In December 2006, the first 30,000-ton phosphoric acid waste heat recovery unit was successfully driven. Up to now, Xingfa has built 12 sets of waste heat recovery devices.

On April 30th, the Yichang Municipal Federation of Trade Unions in Hubei Province granted the inventor of the waste heat recovery technology for phosphorus chemical production, and the deputy chief engineer of Xingfa Group Co., Ltd. won the first prize for the first employee economic and technological innovation.
He graduated from Chongqing University in the mid 90s of the last century. In 2000, he joined the world's largest manufacturer of hexametaphosphate, the Xingfa Group. Yan Ying found that the company consumed a large amount of coal to produce steam on the one hand to provide thermal energy. On the other hand, sodium hexametaphosphate produced a large amount of high-temperature tail gas in the fusion process and directly discharged into the sky. In the face of this contradiction, he boldly proposed to recover waste heat and produce steam to replace coal-fired boilers for heating. With the support of the company, he set up a research team and repeated research and trials. In May 2006, he built the world's first sodium hexametaphosphate polymerization tail gas waste heat industrial device and used its own heat to produce steam. He then presided over the establishment of thermal phosphoric acid and sodium phosphate, sodium metaphosphate and other phosphate heat recovery device.
Nowadays, the new waste heat recovery technology invented by Ying Ying has been widely used in Xingfa Group. Following the installation of the phosphoric acid waste heat recovery unit in branches such as Baokang, Chu-P, and Liucheng, Guangxi, the 12th waste heat recovery boilers have been put into operation at the Liucaopo Chemical Plant, and the coal-fired boilers used in the company's phosphorous chemical production are all shut down.
At the 2007 National Chemical Leaders Forum, Gu Xiulian, the then vice chairman of the Standing Committee of the National People's Congress, praised the development and application of the waste heat recovery technology of the Xingfa Group to shut down the coal-fired boiler. The State Council, the All-China Federation of Trade Unions, the National Development and Reform Commission, the Ministry of Science and Technology, and the State Environmental Protection Administration have commended the Group for the development of circular economy.
