IMPROVEMENT -lN STEAM-GENERATORS.
Specification forming part of Letters Patent No. 221,0 [1, dated October 28, 1879 application filed June 12, 1879.
To all whom "it may concern:
Be it known that I, DAN ABELL, of Carson City, in the county of Ormsby and State of Nevada, have invented a new and Improved Steam-Generator, of which the following is a specification.
The invention consists in combining with a steam-generator feed-water pipes extending through the fines and projecting through an opening at the front and a cap for covering the ends, as hereinafter described.
The invention will be more particularly described in connection with the accompanying drawings, wherein- Figure l is a vertical longitudinal section of a boiler constructed in accordance with my invention. Fig. 2 is a view at the front end, partially in section. Fig. 3 is a rear elevation,
Similar letters of reference indicate corre sponding parts.
The drawings show a horizontal tubular boiler, a, being the main shell, I) the steamdome, c the fire-box, and d the flue-tubes, that discharge into a smoke-box, c, at the rear of the boiler. In the water-space of the boiler, and between the fine-tubes d, there is fitted a series of short vertical tubes, f, which project from below up to near the water-line, and are open at each end, so that they act to increase the circulation within the Water-space. The feed-water pipes (marked lg) connect with the pump at the rear of the boiler through the smoke-box, and pass through the fines d from end to end in a continuous coil, that finally enters the water-space near the bottom of the smoke-box at g. These pipes g extend across the firebox c and through an opening in the I front of the boiler, where the return bends and the boiler there are circulation-pipes 70, which are connected with the water-space of the boiler and with the feed-water pipes g, and extend outside the boiler, so that access may be had .to their cocks lfor closing these pipes 70. These pipes kare required for use to maintain a 'circulation in the feed-water pipes when starting the boiler or when no feed-water is being supplied, and thereby prevent the pipes g from burning out. They are brought into operation by opening the cooks I.
The pipes g will be connected at their ends with the return-bends by screw-joints, and screw-caps may be provided in the bends for permitting the pipes to be cleaned.
The construction described will give a rapid generation of steam with a small amount of fuel, and at the same time facility of access for cleaning and repairs.
By running the feed-water pipes through the flue-tubes and furnace the feed-water is subjected to temperature greater than that of the steam in the boilers. By extending the feed-pipes beyond the end of the boilers the pines maybe cleaned and repaired without interfering with the boiler. By the use of the circulation-pipes kthe feed-pipes are preserved. I do not limit myself to the special form of boiler shown, as my improvements are applicable to other forms.
Having thus described my invention, what I claim as new, and desire to secure by Letters DAN ABELL.
