(2900° F.). The combustible gases leaving the producer are hydrogen (Hj),carbon monoxide (CO), and methane (CH^). By weight these arefor anthracite coal at full load, roughly in the ratio 2 : 30 : 1. 18 SUCTION GAS PLANTS. The incombustible gases leaving the producer consist of carbondioxide (CO2), nitrogen (N^), and oxygen (O^). By weight they WttirDirect from -Town Supply. SVM/VIN SC.

PETAIL8 OF CONSTRUCTION. 19 By weight there are from three to four times as much incom-bustible gases leaving the producer as combustible gases. Inthis respect suction gas compares unfavourably with coal gas,and because of this fact a gas engine working on suction gaswill develop less power at full load than when the engine workson coal gas. It is, however, possible to adjust the gas engine valves so thattlie engine will give better results on producer gas than at firstsight looks probable. The furnace itself is very much the same in all the producerson the market. Different shapes and arrangements of the fire-brick lining are to be noticed, and jjrtjit ingenuity has beendisplayed in altering the details of the grate. In his paper forthe British Association in 1906 Professor Dalby says :— • At the present time there does not appear to
