As has before been mentioned, if the producer could be designed on the lines of a calorimeter, it would have a thermal efficiency of nearly 100 per cent; therefore it would appear that, all things being equal, when the vaporiser forms part of the gasifying apparatus the conservation of heat loss due to radiation would probably be lower than when the heat of the gas is employed to vaporise water in a vessel separate from the producer. At the Derby trials of suction gas producers fourteen competitors entered plants, and after careful consideration the gold medal was awarded to that of the National Gas Engine Company Limited. A diagrammatic sectional view of this producer was given in Engineering, June 22nd, 1906, and is reproduced in fig. 60. The rated capacity of this producer was 20 brake horse power, and during the trials the average braka horse power when running on anthracite was 20-6, and with coke 20-5 brake horse power, on full load. The grate area was 0-72 square feet, and the cross-sectional area 1-31 square feet, the furnace volume being 2-37 cubic feet. The producer casing is of cast iron throughout, and this has the advantage over steel in the matter of corrosion in the parts subject to heat, moisture, and car Fio. 60.--20 B.H.P. Suction Gas Producer.--National Gas Engine Co. bonic acid gas; while the method of building up the firebrick lining prevents the ingress of air through any imperfect joints. Although the vaporiser is internal, consisting of an inner cylindrical vessel fitted with ribs over which the water flows, it is not of the open-boiler type adopted by many other makers. Also, it will be noticed that previous to entering the vaporising chamber the water is heated in a combined external water heater, air heater, and gas cooler. ...
