I would like to ask how to determine the amount of fuel gas required for torch co-combustion?
Thread Content
I would like to ask the experts: after the unit is shut down, the air being released from the replacement system is non-flammable in the flare; fuel gas is used for combustion in order to handle this air. How can we determine the amount of fuel gas required?
Go to the archives to check the design documents for the torch.
Isn’t it required to install flow meters these days?
It is determined based on the types of pollutants present in the exhaust gases and the combustion temperature required of the flare to completely decompose these pollutants. In other words, to reach a certain combustion temperature (for example, a minimum of 1100°C), the flare gas, after having combustion-supporting fuel gas mixed in, must possess a certain calorific value; the amount of such combustion-supporting fuel gas to be added is then calculated accordingly, with an appropriate margin included to prevent failure to meet the specified standards.
