Overview of petrochemical flare system

Flare system heat preservation: in the production of petroleum and chemical enterprises, there are some chemical devices and oil refining devices processing a large number of hydrocarbon substances, in the normal production process is inevitable to discharge a considerable amount of flammable and explosive materials or tail gas, waste gas, in order to prevent fire and explosion accidents, to ensure the safety of equipment and personnel, must be set up flare system. 
According to the support structure can be divided into: elevated torch, ground torch. 
Ground - based flare combustion system insulation: also known as the ground combustion tower, is an environmentally friendly ( effectively closed waste gas ) flare combustion system. 
The ground venting flare system is mainly composed of control valve, ground flare ( composed of burner group, radiation-proof heat shield and protective wall ), and ground flare auto-ignition system. 
The maximum exhaust temperature in the combustion tower is 950 ℃. The temperature of the outer wall of the flare tower is required to be less than 100 ℃.
Thermal insulation structure of ground flare system cylinder

A light ceramic fiber refractory material is laid in the cylinder body and is fixed by a stainless steel wire mesh and bolts; The outer surface of the cylinder body is coated with a high-temperature resistant paint with the temperature resistance higher than 200 deg C.. A: yes, sir
The top of the cylinder body is provided with a stainless steel guide plate, which can bear the scouring of rainwater and flue gas and prevent the heat insulation material in the cylinder body from wetting in rainy days. 
The ceramic fiber lining of petrochemical flare and ground flare adopts a composite structure of layer laying and stacking. 
Total insulation thickness: 180 mm, 150 mm standard fiber module + 30 mm ( 2 20 mm ) tile blanket. 
Aluminum silicate lining material selection 1260 ceramic fiber module and 1260 standard blanket. 
The surface of the ground torch light fiber lining is sprayed with curing agent to resist smoke invasion and wind invasion.
Two installation methods: ( 1 ) vertical torch aluminum silicate fiber lining: ceramic fiber module is installed by overlapping scaffold, and the construction cost is high; ( 2 ) laying the torch aluminum silicate fiber lining flat: after the ceramic fiber module and the ceramic fiber folding block are installed, hanging and installing the torch barrel.
Technical advantage
The water vapor inside the torch is relatively large, and the surface of the ceramic fiber module is coated with curing agent twice, which can resist water vapor and high wind speed flue gas scouring.
