Description

A boiler Introduction The present invention relates to a boiler and in particular to an enclosed boiler, such as an oil ﬁred boiler.

There are many constructions of such boilers and the present invention is specifically directed to improvements in the invention of European Patent No. EP 0616676B, the disclosure of which is included herein in it’s entirety by way of reference. This is a very efficient construction of enclosed boiler. However, since this invention was devised there have been developments directed to improving and making more efficient the method of constructing baffle assemblies for use with boilers of the general type described in EP 06166768. it is therefore an object of the present invention to provide an improved method of constructing baffle assembly based on the principles of the boiler described in the aforementioned European Patent No. 06166763.

It is acknowledged that the term ‘comprise’ may, under varying jurisdictions be provided with either an exclusive or inclusive meaning. For the purpose of this specification, and unless othewvise noted explicitly, the term comprise shall have an inclusive meaning — i.e. that it may be taken to mean an inclusion of not only the listed components it directly references, but also other non-specified components.

Accordingly, the term ‘comprise’ is to be attributed with as broader interpretation as possible within any given jurisdiction and this rationale should also be used when the terms ‘comprised’ and7o'r ‘comprising’ are used.

Further" =,asp'ects.- of the present invention will become apparent form the ensuing description which is given by ’vvay of example only.

Statements of Invention According to the invention, there is provided a method of manufacturing a baffle plate assembly for an enclosed boiler of the type comprising: a substantially rectangular combustion enclosure formed by a base wall, upstanding front, side and rear walls on the base wall, and a top wall, in which at least a portion of the upstanding front, side and rear walls arranged for .carrylng water to be heated; at least one interior tank in the enclosure, which tank extends between the front and rear walls of the enclosure to divide the enclosure in two baffle plate assembly receiving sub-enclosures, each for supporting therein at least one bafﬂe plate assembly, the front, rear and side enclosure walls forming, with the each bafﬂe plate assembly and the enclosure walls, a passageway for flue gases through the boiler from a gas inlet located adjacent the base wall of the enclosure through the baffle plate assembly in one of the sub- enclosures to a common gas ﬂue located in the top wall of the enclosure, the method comprising the steps, not necessarily sequentially of:

Claims

1. A method of manufacturing a baffle plate assembly for an enclosed boiler of the type comprising: a substantially rectangular combustion enclosure formed by a base wall, upstanding front, side and rear walls on the base wall, and a top wall, in which at least a portion "of the upstanding front, side and rear walls arranged for carrying water to be heated; at least one interior tank in the enclosure, which tank extends between the front and rear walls of the enclosure to divide the enclosure in two baffle plate assembly receiving sub-enclosures, each for supporting therein at least one baffle plate assembly, the front, rear and side enclosure walls forming, with the each bafﬂe plate assembly and the enclosure walls, a passageway for ﬂue gases through the boiler from a gas inlet located adjacent the base wall of the enclosure through the bafﬂe plate assembly in one of the sub- enclosures to a common gas flue located in. the top wall of the enclosure, the method comprising the steps, not necessarily sequentially of: 6"?’ fomiing a front bafﬂe mounting plate, a top baffle mounting plate and at least one baffle dividing plate having a pair of side faces and an upward, a downward and front and rear facing peripheral edges, the baffle dividing plate being formed with a plurality of protruding tabs on its upward facing peripheral edge for engagement with respective notches in the top baffle mounting plate, which baffle dividing plate also comprises a plurality of protruding tabs on its front facing edge for engagement with respective notches in the front baffle mounting piate to define there between an opening through which flue gases move; cutting a notch in at least one substantially rectangular base plate to form a substantially U-shaped baffle guide plate having two elongate baffle dividing plate embracing legs; 5 cutting a U-shaped channel forming bend line in one of the legs intermediate its ends; cutting at least one baffle guide plate receiving notch in the rear facing peripheral edge of the bafﬂe dividing plate; 10 bending the baffle dividing plate embracing leg upwards about the U- shaped channel forming bend line; inserting the baffle guide plate formed into the baffle guide plate 15 receiving notch so that the baffle dividing plate embracing legs extend around the side faces of baffle dividing plate to form, with the side and rear walls of the enclosure and the front and top baffle mounting plates, a baffle assembly passageway for directing flue gases through the opening between the front baffle plate and baffle dividing plate and then 20 around the front edge of the baffle dividing plate and along one side face of the bafﬂe dividing plate between the top baffle mounting plate and one of the elongate bafﬂe dividing plate embracing legs and then around the rear peripheral edge of the baffle dividing plate and along the other side face of the baffle dividing plate between the top baffle 25 mounting plate and other of the elongate baffle dividing plate embracing (_ legs and then up the bent portion of the baffle dividing plate embracing a.‘ 33 i""l|eg and through an opening in the top bafﬂe mounting plate to the gas

2. ‘Vflue. 30 2. A method as claimed in claim 1, in which a bafﬂe plate assembly manipulation hole is cut out of the front baffle mounting plate.

3. A method as claimed in claim in preceding claim, in which a further bafﬂe guide plate having two elongate baffle dividing plate embracing legs is formed and inserted into a further receiving notch cutout of the rear peripheral edge of the baffle dividing plate, the bafﬂe guide plate then being tack welded to the sides of the baffle dividing plate. A method as claimed in claim in 3, in which an additional tab is formed on the font peripheral edge of the bafﬂe dividing plate, which additionai tab is inserted into a further receiving notch formed in the front mounting plate. A method as claimed in any preceding claim, comprising the further step of forming a bafﬂe plate assembly extension component, the baffle plate assembly being positioned, when in the enclosure, substantially vertically on top of the baffle plate assembly extension component to provide an extended passageway for flue gasesthrough the enclosure. A method as claimed in claim 5, in which the baffle plate assembly extension component is formed with a baffle plate assembly extension component dividing plate having an upward facing peripheral edge which provides a landing or mounting surface for receiving thereon the baffle dividing plate of the baffle plate assembly. A method of constructing a baffle plate assembly substantially as hereinbefore described with reference to and as illustrated in the accompanying drawings.
