New coal gasification technology – Successful installation of the Xinneng slurry gasifier Author/Source: Yaha Coal Chemical Industry Date: 18-01-2019 Clicks: 158 At 10:58 a.m. on January 14, the gasifier of the Xinneng slurry gasification demonstration unit, constructed by Sinochem 11th Construction Company’s Inner Mongolia branch, was safely installed in one go. The team members involved in the project’s lifting operations are young, knowledgeable, and eager to innovate; they optimized the technical solutions based on the actual conditions of the project. It took only 3 days from the arrival of the equipment at the site to when the conditions were ready for lifting. For the first time, a lifting technique involving the simultaneous handling of the gasifier and the slag crusher was used. The lifting process was safe and smooth, which helped save labor and resources, and it also allowed valuable new experience to be gained, earning praise from peers in the industry. The slurry gasification furnace was independently developed by SNOWTECH; it is capable of processing 1,500 tons of coal per day and has a weight of 244.5 tons. Its advantage lies in the ability to carry out coupled gasification of coal powder and coal slurry within a single reactor, which enhances the adaptability of the technology to different types of coal and improves gasification efficiency. This process represents an innovation in new coal gasification technologies, offering a new production method for the clean and efficient utilization of coal, and it boasts extremely broad market prospects. Hard work pays off, effort yields rewards; take root in place and pursue continuous development. Through the concerted efforts of the project team, the Inner Mongolia branch has managed to establish a foothold in Dalaat Banner’s new energy sector, enabling it to \"enter, stay, thrive, sustain itself, and expand,\" thus securing a space for survival. In 2006, a partnership was established with CNPC for the first time; the first phase of the gasification unit has been operating safely for around 10 years now, offering reliable quality and safety ; The two water-coal slurry gasifiers in Phase 2 were successfully ignited for the first time, enabling continuous and safe operation, achieving full production capacity and efficiency, and thus becoming a benchmark in the industry.

There is nothing impossible if you can think of it; let’s discuss what the concept of slurry-powder coupling is

How many burners and how should they be arranged? One or more on top? Arrange an even number on the side?

New Energy Company has applied for a patent. The present invention relates to the field of coal gasification, and in particular to a co-gasification method for coal. It includes the following steps: Step 1: Inject fuel and oxygen-containing gas at a certain pressure into the gasification furnace, and ignite the fuel to raise the temperature inside the furnace ; Step 2: When the temperature rises to a level sufficient to ignite the water-coal slurry to be injected, stop the injection of the fuel and the oxygen-containing gas at the first pressure; then inject the water-coal slurry and the oxygen-containing gas at the second pressure into the gasifier for the gasification of the water-coal slurry ; Step 3: Once the gasification of the water-coal slurry is stable, the third pressurized oxygen-containing gas and the pressurized carbon dioxide gas carrying coal powder are injected into the gasifier for co-gasification. The present invention provides a coal co-gasification method with stable operation. By ensuring the stability of water-coal slurry gasification before proceeding with co-gasification, operational stability during this process is maintained, eliminating the need for the complicated, time-consuming, and difficult adjustment steps associated with existing technologies.

It also has a wider adaptability to different coal types. What are the main advantages?
