The low-pressure drop auxiliary combustion chamber is a piece of energy-saving equipment used in the petroleum and chemical industries.
The main purpose of this equipment is to solve the problem of large pressure drops occurring in the combustion chamber.
A complete set of low-pressure drop auxiliary combustion chambers consists of the shell, chamber box, burner, primary air inlet, secondary air inlet, and air outlet.
The combustion chamber features a short-cut pipeline, a fast cutoff valve, and a catalyst well.
When the chamber is turned on, the valve is closed, and the primary air goes to the regenerator via the chamber; when the chamber is closed, the valve opens, and most of the air goes directly to the regenerator, avoiding the pressure drop from the chamber, increasing the recycling power of the gas turbine or reducing the power consumption of the main fan.
The low pressure-drop auxiliary combustion chamber is widely used in the FCC, catalytic cracking, and Methanol To Olefin (MTO).
In Ruichang production line, the low-pressure auxiliary chamber is a newly developed product.
Under the normal operation of the catalytic device, the pressure drop can reduce the old auxiliary combustion chamber by more than 80%.
At present, it has been successfully used in large catalytic cracking units of many factories. The good energy-saving benefits of a low-pressure drop auxiliary combustion chambers have been confirmed on the market.
Installation location: between the main fan and the regenerator.
Indicators: In normal operation, the pressure drop range is 0.5 – 1.0KPa.
Take the 2.8 million tons/year catalytic device as an example. For every 1KPa reduction in pressure drop, the electricity consumption is about 200 degrees per hour, and the equipment can run for 6 months to achieve the investment recovery period.
