\ THE Marine. REviEw » ; Power 4 Months Without Cleaning Boilers WITH THE Rogers' Combination Steam Boiler Heater, Purifier Oil Separator and Circulating Device We have successfully run Scotch boilers in marine service six months without taking them out of com- mission, or cleaning. At the end of this period they were practically as clean as new--only a small pail of sand found in the bottom of the boiler. _ Rogers' Purifiers were installed in boilers seven and eight years old. After three months we opened to clean and found the plates stripped of from 4 to 5% bushels of old scale, leaving the sheets entirely bare, as shown by this photograph. Three months previous the whole surface was coated as shown in the lower part of cut. This We Claim 1. Heats the feed water. 2. Purifies the feed-water by removing foreign sub- stances. 3. Separates the oils and greases from the feed-water. 4. Discharges the feed-water at the bottom of Scotch and marine boilers, thus causing a circu'ation and bring- ing the temperature very close--bottom and top--the action of the fire being much above the bottom of the boiler. 5. Dispenses with unequal expansion and contraction tc the greatest extent, thus eliminating large boiler re- pairs, leaky girt seams, furnaces, front and back-head seams, and deterioration of shells. 6. Cheapest and easiest to operate. 7. As efficient as any on the market. 8. Absolutely safe and purely mechanical. 9. Will prevent pitting. 5 : 2 me 10.
