'O' SL Delta Stoker Company North Chicago, Illinois Manufacturers of the Delta Hydraulic Underfeed Stoker Detailed information and descriptive literature may be obtainedfrom dealers or the above address TYPE-- The Delta is an automatic underfeed hydraulic ram type stoker. CONSTRUCTION-- The Delta Stoker is built in fifteen sizes and is available for boiler loads of from 10 to 300 B.H.P. The Delta is constructed in two units. 1. THE GOAL FEEDING UNIT-- This consists of the coal hopper, ram assembly and retort. Coal is fed from the hopper into the retort by means of a hydraulically driven ram. A pusher bar extending the length of the retort provides for even fuel distribution. The retort is of sectional construction explaining why Delta installations meet the individual requirements of each job. The side walls of the retort are air cooled through . tuyeres which provide over fire air, and prevent clinker adhesion. 2. THE DRIVE UNIT-- The drive unit consists of the electric motor, or steam turbine, for driving the forced draft fan and the oil pump for operating the ram. The pump is of the multi-cylinder variable delivery type providing a wide range of coal feed which " may be automatically controlled. A hand wheel at the side of the pump housing regulate the rate of feed. These three units are mounted on a rectangular tank ... which contains the oil for operating the ram. Oil is recirculated. FEATURES-- ;* The Delta stoker may be installed under practically any type boiler, at front, side or rear. Two unit construction makes it possible for the drive unit to be located . at any place in the boiler room remote from dirt and ash and out of the way. An automatic release valve protects the stoker should some uubreakable obstruc tion become wedged in opening to retort. A hand reverse lever is provided on the ram cylinder for quickly clearing jams. The Delta has few moving parts, all Automatically lubricated, and none in or near the fire. These operate at slow ' speeds in a bath of oil at all times, the same oil used as the working. There are no complicated gears or speed reducing mechanisms in the Delta.
