FURNACE OF STEAM BOILERS.

Application filed September 23, 1922. Serial No. 590,12.

like body divided into a number of compart ments open at each end and adapted to be secured underneath the dead plate of the fire grate. At the front end is a steam pipe with nozzles or jets projecting into each compartment and at the rear end are two superposed deflecting plates arranged at diflerent angles, the upper plate advantageously being capable of having its position adjusted. The steam leaving each jet induces a current of air through each compartment which is distributed to the best advantage underneath the grate, producing better combustion of fuel, reducing smoke and efl'ecting consider able economy in the consumption of coal.

In the accompanying drawings Fig. l is a perspective view of a Bunsen blower constructed in accordance with this invention.

Fig. 2 is a side elevation partly in section.

Figs. 3, 4 and 5 are details of a modified construction in which the upper deflecting plate is made adjustable, and

Fig. 6 is a section showing the blower in position in a steam generator of the Lancashire .type.

A' indicates the fan like body, B the steam pipe, and C and D the two deflecting plates.

The body A is constructed from an upper portion and a lower portion secured together by bolts (6 and it is separated into a number of compartments by partitions a which diverge as shown in Fig. 1. At the front end of the body are two lugs a which support the steam pipe B and projecting from the latter are a number of nozzles 72 one of which. enters each compartment. The lower por-' tion of the body is formed with grooves a which rest on supporting bars a which we tend across the boiler flue below the fire grate (Fig. 6)., The deflecting plates C and are respectively attached toand formed in a piece with the lower portion of the body at the rear end and the plate C is arranged at a steeper angle than the plate D so that the air, or air and steam will issue through the upper aperture'at a steeper angle than the air, or air and steam which issue through the lower aperture. In the modification shown in Figs. 3 and 5 the plate C is slidably mounted above the plate D and can be secured in any adjusted position by a set screw 0. This ,constructionenables air and steam to be directed moreto the front, or more to the rear of the grate to suit any particular requirement.

What I claim as my invention and desire to secure by Letters Patent of the United States is 1. A Bunsen blower, adapted to be secured under the dead plate of a. furnace,

comprising a fanshaped body open at each I end and divided by partitions into a series of compartments which arewider at their outlets than at theirinlets, the bottom of the outlet end portion of the body being inclined upwardly beyond the rear ends of the compartments, 2. deflecting .plarte secured over the inclined end portion and arranged at a steeper angle than it, and a steam pipe arranged crosswise of the open inlet end of the body and having a series of nozzles which project into the compartments.

2. A Bunsen blower for use in connection with furnaces, steam generators and thelike comprising a fan like body open at each end the air inlet openings of and adapted to be secured underneath'the dead plate of the fire grate, a number of partitions situated in said body and separating same into a number of compartments which increase in width towards the rear end ofthe body, the bottom of which inclines upwardly beyond the ends of the compartments, a defleeting plate extending across the ends of the compartments above the inclined bottom portion and arranged to be moved towards and away from said ends, means for securing the deflecting plate in its adjusted position, and a steam pipe adapted to be supported across the front end of the compartments and having a number of nozzles one of which projects into each compartment.

In testimony whereof I affix my signature.

THOMAS COLLIER.
