On October 9, 2016, it was reported that East China University of Science and Technology, in collaboration with three other organizations – Sinopec Yangzi Petrochemical, Zhongan United Coal Chemical Co., Ltd., and Sinopec Ningbo Engineering Co., Ltd. – carried out a continuous test run on the SE-Dongfang furnace powder gasification demonstration unit at Yangzi Petrochemical over a period of 28 days. During this test, more than 10,000 tons of Huainan coal were used, and successful clean and efficient gasification of this coal type, which has a high ash melting point and high ash content, was achieved. SE-Eastern furnace gasification technology is a new type of single-nozzle cold-wall pressurized fluidized bed coal gasification technology with independent intellectual property rights, jointly developed by East China University of Science and Technology and Sinopec Group.
I wonder what the parameters for testing coal quality are? What is the amount of flux added? Burning over 10,000 tons in 28 days – is the load too low, or is another type of coal being mixed in?
Burning 10,000 tons of coal per month must involve mixed combustion.

The furnace has a capacity of 1,000 tons. Assuming full load operation, 28,000 tons can be produced in 28 days. Huainan coal accounts for 35% of this amount; the furnace operates at 70% of its capacity, which means a coal mixing ratio of 50%. Is this the type of test being conducted? The cost of coal from Huainan is high; when it comes to final calculations, blending coal with Shenhua coal or using solely Shenhua coal may not necessarily offer any advantages in terms of oxygen consumption. The definite advantage is that it allows more slag to be supplied to the cold-wall furnace.
Is this an energy-saving test? I think there are still some things that need to be calculated; it should be pretty complicated, right?
Does anyone know anything about their fine residues?
The key lies in consumption and syngas metrics; companies still need to make a profit.
