Converter House. Each converter house contained two preheater units, four converter units and four heat exchanger units. The converters were of the regenerative type containing magnesium sulphate. The preheaters were coal fired. Located between the converter house and the burner house is the metal flue for the preheaters. This flue was also shared by the sulphur burners. The converter building is of a steel frame construction and clad with corrugated sheet which has been coated with a bitumen based paint. The converter house has a monitor roof which contained louvres to aid cooling and disperse fumes. The steel main carrying cold SO2 gas can be seen entering the converter house on the left-hand side.

Scrubbing Tower. The scrubbing towers are set in batteries of three per unit. Each tower is packed with coke. The structure on top of the battery is the tank room and below this the distributor room. The gas on leaving the two primary filters entered the bottom of the first tower passing up through the packing material to the top. Acid recovered from the gas percolated down through the coke to a cooler and then drained into a low level feed tank. The gas from the top of the first tower was fed down to the base of the second tower then rising to the top and likewise to the third tower. The gas then passed through the three final stage filters, which also contained coke packing. Thence to the pressure equalizer and blower unit / grease catcher / finally cold gas was fed to the heat exchanger in the converter house.

Burner House and raw materials store. In the Department of Explosive Supply configuration, each burner house contained twelve sulphur burners. This consisted of cast iron pans 2.184400 m x 1.066800 m and 0.1270000 m in depth and set side by side. The sulphur was fed into the pans by hand. The correct burn rate was achieved by regulating the air supply to the burners.

The National Smelting Company, Avonmouth. Contact process for the manufacture of sulphuric acid. The Avonmouth sulphuric acid plant was designed by the Department of Explosive Supply and erected in 1917 for the Ministry of Munitions by Robert McAlpine & Sons. The units were built in pairs, "left-hand" and "right-hand" and faced each other as in the case of the scrubbing towers,three towers per unit, or individual items of plant per unit placed adjacent to one another as in the converter houses. The buildings are of steel frame construction and clad with corrugated sheeting. Brick, tile, lead and wood were used in the construction of the various items of plant. During the nineteen twenties the sulphur burning contact plant was modified to use zinc roaster gases from the Delplace roasters which was the original intention.

This industrial site was first used during the First World War when the government built a munitions plant, providing sulphuric acid for the manufacture of explosives and fertilisers. In 1917, the National Smelting Company built a zinc smelting plant next to the munitions factory.
