Abstract
The combustion of fossil fuel is the major source of greenhouse gases; therefore, fuel switching is viewed as a practical method to reduce greenhouse gas emission. Hydrogen may serve as an alternative for fossil fuel and it is clean. In this study, worthless hydrogen-rich fuel gas (RG), the by-product of the production processes, was led to the fuel system of a industrial boiler in a full-scale petrochemistry plant to partially replace the fuel oil (FO). The result shows that, by changing the inlet RG:FO volumetric flow rate ratio from 1:5 to 1:1.5, the emission of greenhouse gas is reduced significantly. Four sets of boiler loading, including 80, 70, 60, and 50%, were applied to the boiler at the full-scale plant, and the reduction of emission by , , , and can be achieved, which is down by 22.9, 39.8, 43.7, and 47.2%. Meanwhile, the amount of emission can be reduced by 66, 79, 25, and . Therefore, the use of RG to partly replace FO has practical benefits on the reduction of greenhouse gas emission, and better operating conditions for the boiler is suggested at an inlet RG:FO ratio of 1:1.5.
