Definitions
- the present invention relates to an exchange device thermal for a circulating fluidized bed boiler.
- This second exchanger generally consists of several bundles of tubes, each comprising several coils arranged in parallel planes generally vertical. In these beams the fluid circulates coolant, usually water vapor, the whole being integrated in a rectangular container.
- these beams are arranged from the as follows: from a wall of the tank we meet a first beam separated or not from this wall by a space without coil, then a second beam separated or not from the first beam by a space without coil; space between the first and the second beams can include a physical separation such as a low wall or a partition; the any additional beams are arranged so analogous so that the last beam is separated or not by a space without a coil on the wall of the tank opposite to the one next to the first beam.
- the particle supply duct of the fluidized bed dense ET2 is therefore connected to a wall of the tank or to the space free between the first beam and this wall, the return particles at focus C occurring through the opposite wall or by an output connected to the free space between the last beam and this opposite wall.
- the intense mixing of particles tends to homogenize the temperature in the tank, however, as the particles come out of the tank colder than they entered, this temperature is not the same in all respects.
- the tubes located near the particle inlet receive more heat than those who are close to the exit.
- the temperature dispersion is directly related to the size of the rectangular tray. So the temperature of the vapor produced by the first beam disposed at the entrance of the particles is greater than that of the last beam placed at the exit, which is not desirable.
- the present invention thus relates to a device heat exchange which allows to obtain at the output bundles of the second exchanger at a temperature substantially uniform.
- the heat exchange device includes a first heat exchanger followed by a second heat exchanger arranged in a dense fluidized bed, this second exchanger consisting of a plurality of tubular bundles arranged along the path of particles suspended in the dense fluidized bed.
- the second exchanger comprising at least two power supplies located on either side of its center, these power supplies each receive a separate mixture of inlet fluid and outlet fluid from the first exchanger, so the temperature of the fluid entering each beams is an increasing function of its distance to the entry of the particles into this dense fluidized bed.
- Differences in particle temperature in the bed dense fluidized are therefore compensated by the deviations of temperature of the fluids which supply the different bundles.
- An efficient thermal solution when the second exchanger has more than two bundles, consists of providing a clean diet for each of these beams.
- the beams are formed by coils of tubes arranged in vertical and parallel planes.
- the particle path is perpendicular to the plans in which the coils appear.
- a preferred embodiment consists in adopting bundles which are all identical.
- At least one of the mixtures of the inlet and outlet fluids of the first exchanger is produced by control valves connected to the inlet and at the outlet of this first exchanger.
- At least one of the mixtures of the inlet and outlet fluids of the first exchanger is produced by a connected control valve either at the entrance or at the exit of this exchanger.
- the ET2 dense fluidized bed here takes the form of a tank rectangular. By abuse of language the whole bin will be considered the second heat exchanger.
- ET2 tank is connected to an inlet pipe for 2E particles on one of its walls parallel to the planes coils and a 2S particle outlet line on the opposite wall. In this configuration, the flow of particles is therefore on average perpendicular to the planes of streamers.
- the first beam F1 is placed on the entry side particles 2E and the third beam F3 on the side of the 2S output.
- Each beam F1, F2, F3 has its own supply A1, A2, A3 (one input collector) while that there is a single BS outlet collector for all the beams.
- each beam has its own output collector.
- the supply A1, A2, A3 of each of the beams is connected via two control valves to the inlet and outlet of the first heat exchanger ET1. These valves are therefore regulated so that the temperatures at the output of the beams F1, F2, F3 are substantially equal.
- valves could be replaced by a simple diaphragm.
- Another achievement would consist in replacing the two valves associated with a supply by a three-way valve.
- This collector located at the level of the first beam is connected via two control valves at the inlet and outlet of the first heat exchanger ET1, while its end is shown at the third beam is connected directly to the output of this exchanger ET1.
- the BE input collector supplies could be deported and not appear exactly in his ends: what matters is having two sufficiently distant power supplies that are positioned on either side of the center of this collector.
- this BE input collector is provided with a power supply additional arranged substantially in the middle, this feed receiving a mixture of fluids from the input and output of the first heat exchanger ET1.
- the invention allows by means of organs to static or regulated settings to obtain different vapor beams having approximately the same temperature.
- the invention obviously applies if there are two bundles or if there are more than three.
- the invention also applies if any element is inserted between the ET2 dense fluidized bed and the conduit particles S2 of the separating member S (or else between the ET2B dense fluidized bed and the hearth extraction duct C if this ET2B dense fluidized bed is supplied by particles collected in this focus).
- the invention is therefore not limited to the modes of realization described and it can be implemented well ways, if only by replacing a means with a equivalent means.

Abstract
Description
- un foyer C assurant la combustion du combustible en un lit fluidisé circulant de particules, foyer dont les parois comprennent des tuyaux verticaux dans lesquels circule une émulsion (phase liquide et phase vapeur) d'eau produite par évaporation de l'eau qui est introduite à la base de ces tuyaux ;
- un organe de séparation s, généralement un cyclone, qui récupère les gaz et les particules éjectées en haut du foyer pour les diriger dans deux conduits distincts ;
- un premier échangeur thermique ET1, souvent raccordé au conduit gaz s1 de l'organe de séparation S, qui est par exemple un économiseur, un vaporisateur, un surchauffeur ou un resurchauffeur ;
- un lit fluidisé dense ET2 alimenté en particules à partir de l'organe de séparation S, c'est à dire raccordé d'une part au conduit particules S2 de cet organe et d'autre part à la partie basse du foyer C (on peut également prévoir un lit fuidisé dense ET2B alimenté par des particules collectées dans le foyer C, c'est à dire raccordé d'une part au conduit d'extraction de ce foyer et d'autre part à sa partie basse), ce lit fluidisé dense comportant un deuxième échangeur thermique dont l'entrée est raccordée à la sortie du premier échangeur ET1.
- la figure 1, une représentation symbolique d'une chaudière à laquelle s'applique l'invention,
- la figure 2, un premier mode de réalisation de l'invention, et
