Let the data speak: Comparison of consumption rates for Texaco, Shell, Space Furnace, Tsinghua Furnace, and two-stage furnaces

Gasification has been very popular in recent years, with many different types of furnaces emerging in China; moreover, it is said that they perform well and have promising prospects for development. Dear sea friends, please provide your respective data usage figures so that we can compare them. For reference in selecting our gasifier. Projects: 1. Coal quality requirements, cost of coal slurry (coal powder) preparation, coal consumption, oxygen consumption, electricity consumption, and total consumption of effective gas per thousand cubic meters. 2. Burner lifespan, continuous operation cycle, maintenance costs, etc.: accurate data is required; fraud must be avoided
Compared to coal water slurry, pulverized coal gasification is more efficient and requires less input. However, the so-called high efficiency isn’t as remarkable as claimed in promotional materials; this is because high pressure inert gases must be used as a means of transporting the pulverized coal. Only when the issue of transporting the coal powder is resolved can true high efficiency be achieved, and this is also the main reason for the instability in the operation of most pulverized coal gasification systems； The gasification efficiency of water-coal slurry is slightly lower, but its advantage lies in its better stability. The choice of gasification technology depends on what the main product is and what the scale of production is. It also depends on whether the desired gas is primarily CO or hydrogen, among other factors
The question raised by the OP is good, but these can be found on the forum! Many questions have different answers; answer 2# is great! The choice must be made by taking into account factors such as the product, coal quality, investment, and environmental protection; different levels of expertise also lead to various answers! The level of skill is really important!
Each has its own advantages, and it cannot be generalized
