JAMES C. ECKLIFF, OF DETROIT, MICHIGAN, ASSIGNOR TO ECKLIFF AUTOMATIC BOILER CIRCULATOR COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.

WATER-PURIFIER.

Application filed August 23, 1918.

To all whom it may concern Be it known that 1, JAMES C. ECKLIFF, a citizen of the United States, residing at Detroit, county of lVayne, State of Michigan, have invented a certain new and useful Improvement in Water-Purifiers, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to water-purifying systems for boilers and has for its object the provision of a number of members that 00- operate together to purify the water and do away with the necessity of filtering the feed-water.

In the drawings: Figure 1 is a vertical cross section of a steam boiler. Fig. 2 is a vertical longitudinal section of the same.

Heretofore in order to prevent foreign matter being deposited upon the hot surfaces, such as the crown of the furnace chamber, the crown sheet of the combustion chamber and the fines, filtration of the feedwater has been employed. It is quite necessary, especially on boats on the lakes and rivers, also locomotive and stationary boilers, to prevent the deposit of mud, sand and other foreign material upon the hot surfaces, for it bakes and becomes scale. This scale is deleterious to the internal parts of the boiler and must be removed at short intervals. The removal is not only an expense but it means that the boiler fires must be extinguished for a period while the scale is removed.

The present invention prevents the formation of scale and does away with filtration of the feed-water, which is not entirely satisfactory. At a temperature of 212 degrees Fahrenheit, a considerable precipitation takes place, but not complete precipitation. Between 300 degrees to 350 degrees Fahrenheit complete precipitation of all extraneous matter in the water occurs. Most boilers have temperatures ranging from 335 degrees to 4.10 degrees Fahrenheit.

It is the object of this invention to utilize such temperatures to precipitate the extraneous material to a point below the hot surfaces from which it may be automatically removed, thereby eliminating the fre- Specification of Letters Patent.

quent cleansing of boilers, and thereby preventing scale. To accomplish this several old devices are used in a new relation.

Referring to the drawing, the boiler shell is indicated as a, the furnace as b, the combustion chamber as c, the fiues as (Z, and the stay-bolts as e. A temperature balance f comprises a leg running up over the side of the furnace and an arm extending along the top of the furnace lengthwise of same. This is only one form of a temperature balance; other temperature balances might be used provided they positively equalize the temperature at top and bottom.

Temperature balances have already been used for the purpose of equalizing the heat of the water in boilers. Such equal heating prevents uneven expansion and stresses upon the boiler shell, the furnace shell, the combustion chamber shell and the flues. It is the purpose of this invention to heat the feed-water for another purpose, namely precipitation.

The feed-water is introduced at the bottom of the boiler so as not to be in a position to drop the particles of extraneous matter suspended in it upon surfaces where they will be baked or from which they cannot be removed. Ordinarily the introduction of the feed-water at the bottom would be a dis advantage as it would mix with the already colder stratum at the bottom and make a still greater disparity of temperatures in different locations in the boiler. The feedwater pipe is indicated at g and the injector at it. As soon as the feed-water enters the boiler it meets the hot currents set up by the temperature balance and itself becomes heated to a high temperature. This rise in temperature takes place almost immediately and before the new water has a chance to rise above the furnace, combustion chamber, or lines. This high temperature so soon attained immediately precipitates substantially, if not all, the foreign matter in the water before the new water has an opportunity to rise above the heated surfaces.

The precipitation takes place directly on the bottom of the water chamber of the boiler. Here it is not subjected to such intense heat as to become baked, nor is it given time to become caked on the bottom; for the final step in the invention is to remove the sediment from the bottom of the boiler by the aid of the steam and its pressure. The blow-01f should be operated at regular intervals to prevent accumulations which might be deposited on highly heated surfaces by the temperature balance. To accomplish this, a blow-oil 2' is provided, consisting of a main pipe and a plurality of equally spaced legs 7'. These legs'together with the main pipe reach comparatively high upon the sides of the boiler to take in the whole area upon which the precipitation takes place. The legs are substantially equally spaced so as to aiford an equal chance for discharge from all points on the area of deposit. The discharge valve is may be opened whenever it is desired to sweep the bottom of the boiler and the sediment eliminated before it has time to cake.

It will be noticed that the temperature balance can be used to perform its old function of equal heat distribution and can also act in the new combination to attain a purification of the boiler water without deposit on surfaces that cannot be swept while the boiler fires are burning.

I What is claimed 13-5 v a,

1. A water purifier for boilers, having in combination with the steam generating boiler, means for substantlally equalizing boiler, a temperature balance for ma-intain-' mg substantially equal temperatures for the water in all parts of the boiler, means for introducing the feed water into the boiler adjacent the bottom of the boiler, and a blow off for completely sweeping the bottom of the boiler.
