The blow-nii" pipe or pipes 15 extend' n the side opposite the inner ends of the ubes #i us shown in I`ig. l, so that when the now-0E valve is opened the 'Water Will rush across che box sweeping the sludge toward :ind through the blow-off pipe. As the streams or" water will converge toward the blew-off ipe. deposits atene ends and other peres of t ie box may not be entirely remore Provision is therefore ine de for causing t na'ter eo I'iow adjacent to tbe ends and all other parts of ilie box toward the outlet or blow-ofi pipe. To this end e Wall or mtirien 'i6 is so arrnnged long ,z'itudinfill)I of the box end preferably secured to its side wall :is shown, so es io form ev blow-off chamber .viii which elle blowbf pipe connects. A

As llie bolos are disributed along the entire length ofthe partition, all parts of the box Vwil be brought under the action of the water lowingfrom the tubes 4.

I claim herein as my invention:

1. The' combination with a Water tube boiler, of a box arranged in one of the drums to inclose and isolate the ends of n portion of thecrculating tubes, and the blow-off nozzle, and a perforated partition interposed between the ends-of the tubes and the blow-off nozzle. i

2. The combination with a water tube boiler, of a box arranged in one of the drums to inclose and isola-te the ends of n portion of the circulating tubes and the feed and blow-oif nozzles, a. portion of the side or outer Wall of the box being detachable.

3.4The combination With a Water tube boiler, of a box hinged to the drum and adapted to inclose and isolate the ends'of a portion of the circulating tubes and the feed und blow-Oifnozzles, e portion of the main vor outer Wall of the box being detachable.

4. The combina-tion with a Water tube boiler, of a. bon hinged to the drum md adapted .to incloseandisolate the ends of e. portion of the circulating tubes and the feed and blow-oil' nozzles, a portion of the box being detachable, and Ineens for holding the.

box and detachable sition.

5. The combination with n Water tube boiler, oi a box arranged in one of the drums portion in operative poto inclose ,and isolate the endsof a portion z my hand. 1
