In recent years, many places have adopted "coal to gas" and other methods. However, in actual operation, problems such as high costs and "gas shortage" have arisen. Coal-fired coal is still in many provinces for some time to come. The "protagonist" of the energy structure. At present, Hebei Province is trying to use "micro-coal atomization" technology to promote clean coal utilization.
It is estimated that the use of "micro-coal atomization" technology to transform the traditional coal-fired boiler, combustion efficiency increased to 98%, thermal efficiency increased to 90% or more, tons of coal steam from the traditional boiler of 5.5 tons to 9 tons or more. Compared with traditional coal-fired boilers, it can save more than 30% of coal, save 20% of electricity, save 10% of water, and save 50% of land. Coal ash is completely burned, and it can also become a high-grade cement clinker, achieving a clean and efficient process.
According to the implementation plan, this year will complete the boiler steam reform of 5000 tons/hour, accounting for 25% of the total plan. In 2016, it will complete 6,000 tons of steam and in 2017 it will complete 9,000 tons of steam. In the first half of this year, 11 cities and provinces and municipalities directly under construction started construction of a project with an installed capacity of 100 tons of steam per hour or more. Among them, 4 cities in Beijing and Hengshui have started to build 2 installed capacity of 100 tons per hour. Hours above the item. In areas where the province's coal-fired boilers are relatively concentrated, new centralized heating (steam) stations will be built in the industrial parks, and coal-fired boilers of the original enterprises will be eliminated, with minor customs clearance and planning to transform 10,000 tons/hour. At the same time, it actively intervened in the boiler renovation projects of central enterprises and group customers.
In the future, coal-fired boilers that have been transformed from "micro-coal atomization" in Hebei Province will adopt BOO (build-own-operate), BOT (build-operate-transfer), and EMC (contract energy management) models. After the energy-saving transformation of traditional boilers in existing industrial parks, industrial enterprises, and residential communities, EMC will be adopted.
RMB 18 billion to Transform the Boiler with "Micro-coal Atomization"
"Micro-coal atomization", such a sounding professional technology, is an integrated technology for the clean and efficient use of coal. As a result of the aerospace vortex technology, the micro-coal after processing and disposition achieves high-efficiency atomization, and the gas and air are fully burned. Together with the low-temperature and low-nitrogen combustion technology, the sulfur dioxide and nitrogen oxides are greatly reduced, reaching the gas boiler emission standard, so the entire No smoke and dust can be seen during the combustion process.
