Thisdevice adds largely to the water capacity of the boiler, fre-quently containing one-half the weight of the water held in theboiler itself. It will be readily understood that the openings between thevertical tubes are ample for the chimney flue area and that thedevice is located between the chimney and the boiler, with thewaste furnace heat passing between the Fig. 93. The economizer shown in Fig. 93 consists of sections of vei-tical 4^ boiler tubes fitted to their top and bottom headers bytaper joints. The top headers are provided with caps overeach tube to permit cleaning out the sediment and remove andreplace any tube that may become damaged. The several topheaders are connected together at one end by lateral openingsand the bottom heai!ers are also connected as shown in cut,having hand holes opposite each bottom header to provide forcleaning out. Maxims and Instructions. 187 FUEL ECONOMIZER AND FEED WATER PURIFIER. Mechanical scrapem are made to travel up and down eachtube to keep them clear of soot. These are controlled by anautomatic mechanism and driving head, as shown in Fig. 93. The important features about the economizer are, 1, itsadaptability to any type of boiler, 2, the saving attained byutilizing that heat which has necessarily been an almost totalwaste, 3, the purifying of the water by means of the intenseheat and slow circu
