2. Project Description
Taian Xinhuan Energy Clean Energy Co., Ltd. is a large-scale scientific and technological innovation private enterprise specializing in the market research and development, production and promotion of high-efficiency coal powder, coal water slurry, coal water slurry additives and gasification water coal slurry additives. The company occupies an area of 67,000 square meters, has professional and technical personnel with advanced domestic production and laboratory equipment, and has more than 100 employees, of which technical personnel account for 30%. The company has always focused on the development and application of high-efficiency coal powder and coal water slurry.
3. Design principles
(1) On the premise of meeting the requirements of production scale, the host adopts stand-alone and single-line equipment to achieve the purpose of smooth and compact production line, save land, and increase land use rate.
(2) The auxiliary equipment is based on the principles of stability, reliability, and energy saving to ensure normal production, high quality, high yield, and low energy consumption.
(3) Fully integrate the local natural conditions, optimize the design plan under the process and production conditions, and reduce the project cost as much as possible.
(4) Conscientiously implement relevant environmental protection, laws, regulations and standards, strictly control environmental pollution, reduce pollutant discharge, protect and improve the environment, and realize safe and civilized production.
4. Project Implementation
The first phase of the 250,000 tons of pulverized coal preparation project was publicly tendered across the country. Because the new environment has a greater influence in the industry, well-known suppliers in the industry rushed to sign up during the tender, and eight peers participated in the bidding. After more than one month and 3 rounds of fierce technical and commercial bid evaluation and bid negotiation process, due to the advantages of excellent product quality and many achievements in coal preparation, Zhengzhou Mining Machinery finally won the bid in July.
After winning the bid, our engineering and technical personnel overcome a number of technical difficulties according to the technical requirements of the bidding documents, and carried out careful and detailed engineering construction drawing design, and passed the review at one time. In strict accordance with the contract requirements, the project department formulated a rigorous implementation plan, equipment manufacturing, installation, shipment, commissioning, etc., with the active cooperation and support of Party A’s project department, the project was completed on time and the commissioning was smooth.
During the trial production process, our after-sales service personnel stayed at the site for more than one month, and dealt with and eliminated problems such as the vibration of the separator and the air leakage of the valve seal.
The positive working attitude, rigorous work style, excellent product quality, and good after-sales service have won the recognition and praise of Zhengzhou Mine by the leaders and employees at all levels of Xinhuan Energy.
The project was accepted as qualified in August 2018. It once again demonstrates the powerful equipment manufacturing capabilities, perfect technical design capabilities, and complete engineering service capabilities of Zheng Mining Machinery. Contribute to the effective promotion of clean energy in Shandong.
