Gas Fired Reformer

Problem

The feed rate of the furnace was restricted due to temperature constraints and the flue gas temperatures had exceeded their maximum sustainable temperature.

Furnace performance was reduced due to build-up of scale and combustion related fouling on furnace tubes.

Gas Analysis

Density: 5.28 KG/m3
Mol Weight: 20
Calorific Value: 40 mega joules/KG

After Therma-Chem Treatment

The scale within the furnace was broken down increasing the heat transfer. This resulted in a flue gas temperature reduction from 1066°C to 910°C at a feed rate of 42m3/hr after only 6 weeks.

The temperature reduction of 156°C was accompanied by a corresponding increase of 7 tonnes/hr in the load, equivalent to a 20% increase.
