Abstract

Conversion processes that involve large amounts of energy include processes in furnace reformers in
the steel industry. The reformer unit used to convert the process gas, namely a mixture of gas and
steam into CO and H2 gas with the help of a nickel catalyst. The heat energy used in the process is the
result of combustion from natural gas using combustion located above the furnace. The most important
thing in the conversion process is the radiative heat transfer in the combustion chamber to the reaction
pipe wall so that enough energy is obtained to carry out the conversion process. One way to determine
the heat distribution of the reformer combustion chamber is to know the temperature profile along the
reaction pipe, including the pipe wall temperature, the process gas temperature, and the temperature
of the combustion gas used as energy for the process in the reformer furnace. The performance
evaluation of the reformer furnace uses a mathematical model for combustion in the furnace which can
later be developed by knowing the fitting composition of the conversion results. The type of reformer
studied is the top-fired reformer. The results of modeling using data from the steel industry obtained the
highest temperature from the combustion of gas from the burner which is in the reaction pipe at a
position 3-4 meters from the upper end of the reformer around 1300 oC and the temperature of natural
gas-steam in the pipe reaches 860 oC at the end of the pipe. reaction. The pipe wall heating with natural
o o
gas fuels provides a maximum temperature ranging from 890 C - 895 C on the outer wall of the
reaction pipe, and the pressure inside the reaction pipe ranges from 8.0-8.5 atm.
