Pressurized equipment located upstream or downstream of multi-tube exchangers, this type of tank allows a liquid phase to be accumulated so as to balance the flows over the entire fluid circuit.
Thermal specificities:
Quiri, specialist in heat exchangers, introduces you a buffer tank.
The buffer tank supplied by Quiri is part of a set of 4 heat exchangers: vaporizer, tank and 2 sub-coolers.
The project consists of the construction of a cogeneration plant running on biomass and supplying heat in the form of steam and hot water to 2 industrialists near the site.
The vaporizer is powered by steam drawn from the turbine and will produce steam for industrial use.
The primary condensates (steam turbine) will be returned to the boiler feed tank.
The secondary condensates come from the industrial.
The function of this tank, designed by Quiri, is to keep a certain volume of liquid water in order to guarantee the presence of liquid in the sub-coolers. This tank is also used for regulation on the primary side.
