A modified wheelcase will be required. Condenser and Air Inlet. The condenser is of the form best adopted for ejecting air, and has a frontal area slightly greater than the fan disc. There is a short distance between the fan and condenser matrix to enable the fan cowling to change from one shape to the other. We are asking for an air inlet through the deck of the tank to the condenser 40 inches wide by 14 inches deep, approximately 4 square feet. Water Header Tank & Separator. The header tank is situated as high up as possible immediately behind the air inlet and passes across over the top of the fan cowling. We should require to know more exactly the shape of the deck to fix particulars of this tank. A filling and inspection cap is required for the header tank and this is shown projecting through the deck. The separator dealing with the steam and water delivered from the engine is shown in the inside end of the header tank. Steam is taken from the middle of the header tank and delivered by a pipe to the bottom of the condenser. Hot Well Pump - non-return valve and filter. The hot well pump consists of a small gear pump fitted on to the end of and driven by the existing centrifugal water circulation pump. It has a capacity of twice the maximum rate of condensation and is arranged to be self priming and self lubricating. This pump draws away the condensate from the tank of the condenser via a strainer and non-return valve and Continued | ||
