Abstract:
The group of inventions relates to installations (including boiler installations) which use a heat carrier to fulfill the functions thereof, and also to units and structural elements used in such installations. Specifically, the distinguishing characteristic of the system of boiler equipment is a composite body comprised of elements, the number of which corresponds to the number of units. The body elements are assembled so as to form, in the top part of the body, at least one channel for receiving pipelines and/or wires, said pipelines and/or wires connecting the electrical equipment of the units. A distributing heat-carrier collector is laid along the length of the body and is also comprised of component elements, the number of which corresponds to the number of units through which the heat-carrier passes. The pumps of such units are installed vertically on the uppermost horizontal cross-piece of the body, with the engine on top. The claimed group makes it possible to increase the compactness, ease of repair, and ease of replacing the entire system or individual units thereof, to unify such units, and also to undertake the installation of said units without the additional use of special equipment.

The pumping unit (A) comprises a body (1) with an outlet (3) and a first inlet (2), for connection to the primary heat exchanger (21) and to a return pipe of the heating circuit (22, 24), respectively, and with a second inlet (4) intended to receive a flow of heating water from the secondary heat exchanger (25). A circulation pump (7) and a three-way solenoid valve (8), in series with one another, are provided between the outlet (3) and the first inlet (2) in the body (1), the valve being further connected to the second inlet (4). The by -pass conduit (31) is formed inside the body (1).

Abstract:
A one-piece tube for use as a watertube within a watertube boiler or heat exchanger has a free end section that is formed to have an integral, outward-extending circumferential ring, or flange, a spaced distance from an adjacent end face of the tube. A boiler is provided that has an elongate header and a plurality of separate watertubes each having an intermediate section and opposite end sections. An end section of each watertube is connected to the header. The intermediate section of each watertube has a substantially constant outer diameter along its full length and is closely spaced to adjacent watertubes within the combustion chamber. At least one of the end sections of each watertube has a transition that reduces the diameter of the watertube as it extends from the intermediate section to an outwardly-extending circumferential flange. This arrangement permits close spacing of the connection sites of the watertubes to the header and permits the connection sites to be provided in a linear array.
