ALFRED WILLIAM BENNIS, OF BOLTON, ENGLAND.
WATER-HEATING AND STEAllE-GENERATING BOILER.
Application filed August 'The present invention relates to improvements in water heating systems and more particularly to water tube steam generators.
The invention is described with particular reference to water heating or steam generating boilers in which inclined water tubes are connected in banks to headers, water legs or to drums at the front and rear of such banks, all in appropriate combination with main steam, water and mud drums, and other connections.
One object of the present invention is to provide a more eticient arrangement of the heating surface of the inclined tubes by which a portion of the heating surface of the tubes is removed from the rea'ward or exit portion of the boiler and placed in the forward or first pass portion of the boiler where such heating surfaces will be subject to the more intense hoat of the furnace.
It is further desired to einploy vertical or semi-Vertical, circulating tubes passing between the tubes of the upper portion of the boiler in a location suitable for the support of a battle wall Situated between the first and second pass of the boiler.
According to the present invention the main boiler tubes are divided into two or more separate banks, the upper bank being materially longer than the bank immediately below it.
The invention is more particularly described with reference to the accompanying drawings, in which:
Figure 1 is a View in eleVat-ion of one form of construction and arrangement of the tubes of the boiler according to the present invention, the tubes being inclined in one direction, namely upwardly from front to rear of the boiler.
Figure 2 is a View in modification of Figure 1, in which the upper bank of tubes is inclined in an opposite or different direction to the lower bank of shorter tubes.
In water tube boilers it has generally been the practice to arrange the main water tubes in groups or banks which are of similar length. By the invention the banks of tubes are of differing length. As may be seen from Figura 1, products of conbustion from a chain grate or other furnace 1 passcs up through a bank of short tubes 2 inclined upwardly and then through the first pass of a second bank of tubes 3 whence they are defiected to pass down on the opposite side of the partiton wall 4: through the second pass Serial No. 47,929.
of the bank of tubes 3 before proceedin to the exit fiue 5. g
A superheater unit 6 may be placed in the space between the banks of tubes 2 and 3. In the arrangementshown the headers 7, 8 of the short bank of tubes 2 connects direct by pipes 9, 10 respectively, to the front drum ll and intermediate drum 12, whilst the bank of tubes 3 has its own ppe connections 13, 14: to the front and rear drums ll, 15.7 The drum ll is, therefore, common to both banks of tubes. Connections 16, 17 are provided between the drums 11, 12 and 15.
Figure 2 shows an arrangement by way of example where the lower short bank of tubes 22 lies at a different inclination, namely, upof the long bank which are inclined downwardly.
It will be obvious that many further variscope of the appended claims.
1 declare that what I claim is of tubes whilst the two others are each separately connected to the headers at the opposite ends of the banks of tubes.
2. A water heating and steam generating boiler comprising in combination a furnace grate, a short bank of boiler tubes and headers at each end thereof, through which the furnace gases pass directly terially longer bank of tubes and headers at each end thereof oppositely inclined to the short bank of tubes, and three drums above said banks of tubes, one drum being common to one end of both the short and long bank of tubes, whilst the two others are each separately connected to the headers at the opposite ende of the banks of tubes.
3. A water heating and stean generating boiler comprising in combination a furnace grate, a short bank of boiler tubes and headers at each end thereof, through which the 15 placed with rega-rd terially longer furnace gases pass directly upwards, a mabank of tubes and headers at each end thereof, a partition Wall dviding the length of the longer bank of tubes and lying substantially in the plane of an end header of the short bank of tubes, and three drums above said banks of tubes, one drum being common to one end of both the short and long bank of tubeswhilst the tWo others are each separately connected to the headers at the opposte ends of the banks of tubes.
t. A Water heating and steam generating boler comprising in combinaticn a furnace grate, three upper drums horizontally disto one another, pipo connections between 'said drums, a short bank of tubes through which all the furnace gases pass directly Upward, a materially longer bank of tubes, connection pipes to connect said tubes of the shorter bank to one end drum and the central drum, connection ppes to connect said tubes of the longer bank to both end drums, and a partition Wall dividng the length of the longer bank of tubes, said Wall being supported by the connection 25 ppes from said central drum to the shorter bank of tubes.
In Wtness Whereof, I have hereunto signed my name this 22nd day of July, 1925.
ALFRED VVILLIAM BENNIS.
