Review Meeting for the Process Package of Jinhua Furnace Gasification Technology Held / Author/Source: Jinhua Furnace / Date: 2020-05-29 / Clicks: 18. From May 26th to 27th, a review meeting for the process package of Jinhua Furnace gasification technology related to Shaanxi Qingshui Yinquan Coal Industry Development Co., Ltd.’s 2x60,000 tons per year melamine production project was held in the conference room on the 12th floor of Yinquan Coal Industry Company. Relevant personnel from Shaanxi Qingshui Yinquan Coal Industry Development Co., Ltd., Beijing Qingchuang Jinhua Technology Co., Ltd., and China Chengda Engineering Co., Ltd., along with invited experts, attended the meeting. During this meeting, in-depth exchanges and discussions were held among the participants regarding the process package data, configurations, and design parameters, creating favorable conditions for the next steps of work, accelerating project implementation, and providing a foundation for design and construction. The 2x60,000 tons per year melamine project of Shaanxi Qingshui Yinquan Coal Industry Development Co., Ltd. utilizes the water-cooled wall waste boiler gasifier technology for coal slurry (Jinhua Furnace 3.0) developed by Beijing Qingchuang Jinhua Technology Co., Ltd. The gasification unit operates in a two-in-one-backup configuration, with a gasification pressure of 6.5 MPaG; the effective gas production per furnace is 100,000 Nm3/h (CO + H2). The construction site is located in the Qingshui Industrial Park, Yulin City, Shaanxi Province. The water-cooled wall waste boiler gasifier technology for coal water slurry (Jinhua Furnace 3.0) is a new type of gasification technology with complete independent intellectual property rights. It achieves direct connection between the coal water slurry water-cooled wall gasification chamber and the radiant waste boiler for the first time, breaking foreign monopolies in the field of waste heat recovery technology for syngas produced in coal water slurry gasifiers. Compared with similar technologies at home and abroad, the Jinhua Furnace 3.0 improves the system’s thermal efficiency while also enhancing its adaptability to different types of coal. It provides the technical infrastructure necessary for the efficient and clean utilization of various carbon-containing solids, including those characterized by high calorific value, high ash content, and high sulfur content. It offers advantages in terms of energy consumption and environmental performance, as well as in system reliability, investment costs, and operating expenses. It enables integrated applications in the fields of chemicals, power generation, gas processing, and heating. Compared with water-cooled wall quenching gasification for coal water slurry, it has the following advantages: with unchanged oxygen and coal consumption, 0.8 tons of steam can be produced as a by-product per k(CO+H2); the flow rates of the quenching water pump and the high-pressure ash water pump are reduced to about 30% of those designed for quenching gasification furnaces, resulting in a 10 kWh/k(CO+H2) reduction in electricity consumption; the load on the ash water system is also reduced to about 30% of that in quenching gasification furnaces, leading to lower equipment investment. The gasification framework and the ash water treatment framework are integrated, which facilitates operation, maintenance, and inspection. The pipelines between the originally designed gasification framework and the ash water framework are shortened, reducing the floor area by 1500 m2 and lowering the costs associated with civil works and process pipelines.
This technology is good; heat recovery is its main feature. Is Siemens abroad following this approach?

“The \"Jinhua Furnace\" was independently developed over 17 years by Yangquan Coal Group in collaboration with Tsinghua University. It has been recognized as a key asset in China’s coal chemical industry. It boasts the stability and reliability of water-coal slurry gasification furnaces, as well as the advantage of good adaptability to different types of coal in terms of water-cooled wall gasification furnaces. It is particularly suitable for the gasification of coal with high ash content, high sulfur content, and high ash melting point – characteristics often referred to as the \"three highs\". This furnace meets strategic requirements such as energy security and environmental protection, and it offers significant economic and social benefits.
On January 6, 2020, on the occasion of the 70th anniversary of Yangmei Group’s construction enterprise, a press conference for Yangmei Group’s “Jinhua Furnace” gasification unit was held at Shanxi Yangmei Chemical Machinery (Group) Co., Ltd. 116 experts, scholars, entrepreneurs, and others from the national coal gasification industry attended the press conference to discuss the future development model of the Jinhua furnace gasification island. At the meeting, reporters learned that the Jinhua furnace series, a key technological achievement developed through cooperation between Yangquan Coal Group and Tsinghua University, has now reached its third generation, becoming one of the main types of water-coal slurry gasification furnaces in China. The Jinhua Furnace 4.0 under development will feature a total heat recovery gasification furnace, enabling full recovery of the heat generated by the gasification process; this will allow the steam production to increase by another 40%–50%, with its overall technology ranking at the international leading level. In addition, Yangmei Chemical Industry has invested 510 million yuan to collaborate with American companies GTI and Donghua Technology. By utilizing American aerospace technology, it is developing R-GAS gasifiers for use with coal in China that has a high ash fusion point and a temperature of over 1,500 degrees. An industrial demonstration plant with a capacity of 800 tons per day has already been built in the Qingxu New Materials Park. This will enable the local sourcing of coal for gasification purposes in Shanxi Province’s coal chemical industry, thereby playing a positive role in promoting the development of this industry there.
