Clean coal phase 4 desulfurization liquid cooling project (L- Ferrous and nonferrous metallurgical engineering)

Baoshan Iron and Steel Co., Ltd. (hereinafter referred to as "Baosteel") is the world's leading modern steel joint venture and the core enterprise of China


Baowu Iron and Steel Group Co., Ltd., a fortune global 500 company, listed on Shanghai Stock Exchange (stock code: 600019). Among the listed steel enterprises in the world, it ranks the second in crude steel output, the third in automobile plate output, and the first in oriented electrical steel output. It is one of the steel enterprises with the most complete varieties of carbon steel in the world.

Baosteel adheres to the development path of "innovation, coordination, green, open and sharing". The company pays attention to the cultivation of innovation ability, actively develops and applies advanced manufacturing and energy-saving and environmental protection technology, and has established a nationwide and worldwide marketing and processing service network. The new-generation auto high-strength steel, electrician steel, high-grade home appliance steel, oil and gas pipe, bridge steel, hot rolling heavy rail, and other high-end products, independently researched and developed by the company, are at the international advanced level.

A - BLOC four sides detachable all-welded heat exchanger is applied in clean coal phase 4 desulfurization liquid cooling section, used for the cooling of desulfurization liquid by the circulation cooling water. In consideration of the actual production of corrosion resistance and easy disassembly and washing, the plates of the A-BLOC all-welded heat exchanger are made of square BLOC sheets, and the plates are fully automatically welded with one another. Special structural design is different from other forms of fully welded plates, can achieve pure countercurrent heat transfer, (other products of the wrong countercurrent heat transfer), can produce higher turbulence. In the same operating conditions, the A-BLOC all-welded heat exchanger has a heat transfer coefficient four times that of the tubular heat exchanger, with a smaller area required and the ability to handle very small heat transfer temperature differences. In the case of high thermal stress, the plates can be freely telescoped within the frame to effectively resist thermal shock, thus extending the service life of the equipment.
