30×500KW Flue Gas Power Plant in China

Shengdong supply INDUSTRIAL FLUE GAS ENGINE GENERATOR SYSTEM, IN-CYLINDER® intake control technology
Industrial flue gas is a collective name of flamable gas generated from:
● Coal coking process (coke oven gas) and
● Iron oxide reduction process (blast furnace gas). Or
● Other pyrolysis process (biomass, waste plastic/tyre, etc).
● And manufacturing process of calcium carbide (CaO+3C→CaC2+CO)
This kind of flammable gas is widely available in coking plants, steel mills and other metallurgical plant (with smelters, for production of alloy materials like manganese and nickle).
In general, this gas is normally a byproduct of manufacturing process.
Typical composition of flue gas is as following:

Steel production gas type	Coke Gas	Blast Furnace Gas	Converter Gas
Source	Coke oven battery	Blast furnace	Converter
Input	Coal	Coke & iron ore	Pig iron
Output	Coke	Pig iron	Steel
Hydrogen %	50-70%	5%	-
Methane %	25-30%	-	-
Carbon monoxide %	-	20%	60%+
Lower heating value kWh/Nm³	~5.0	~0.9	~3

● Major flammable compositions are CO (carbon monoxide), H2 (hydrogen) and CH4 (methane).
● Flue gas composition is relatively unstable and can change from time to time.
● Raw flue gas contains different comtaminants like tar, H2S, and dusts/particluers.
● Ferro-Alloys include FeCr, FeMn, FeSi, SiMn, Si-Metal, TiO₂ and less commonly FeTi, FeNb, FeV, FeNi as well as calcium carbide used to produce acetylene. The furnaces whether closed or open all produce combustible gases of varying compositions and calorific values. The combustion behaviour of these gases places considerable demands on engine design. Shengdong offers specially 700Kw gas engines that efficiently burn these gases for the combined generation of heat and electricity.
● The high hydrogen content of some of these gases results in a fast combustion process which increases the danger of engine knocking or backfiring. To reduce this risk, Shengdong has created an engine fuel control system. Some of the components of these gases, e.g. carbon monoxide have a slow combustion speed and the gas itself is toxic.
● Shengdong has developed specific gas engine combustion systems that allow the burning of these gases efficiently and reliably whilst offering a safety technology package that allows safe handling of harmful gases such as carbon monoxide. Both gases can both be used to electricity.
Shengdong had been aggressively promoting gas engine technology in this sector in the past two decades, and a lot of experiments and tests were conducted, and various pilot plants were constructed to use this type of gas for power generation.
Shengdong gas engine’s ‘IN-CYLINDER’ technology is a proven solution for fuel gas which mainly contains hydrogen and carbon monoxide. Originally this technology is developed to suit the requirement of producer gas, however industrial flue gas power plants in China, proved that IN-CYLINDER technology is an ideal solution for industrial flue gas power generation.
