INSTALLATION FOR HOT-WATER HEATING AND/OR HOT WATER SUPPLY Russian patent published in 1999 - IPC

FIELD: heat power engineering. SUBSTANCE: installation uses a gas heat generator with a cooling system, and a gas conduit, communicating with the heat generator, installed in which in succession in the direction of motion of heated gas are the first heat exchange system, a hot well with discharging chutes and the second heat exchange system; the heat exchange systems have at least one heat exchanger in the form of a stack of plates. The hot well is made up at least of two rows of V-shaped sections, whose projections onto the horizontal plane cover the entire section of the gas conduit. The plates of the heat exchangers are made of metal plates, in which two zigzag channels are formed for passage of liquid, channel inlets and outlets communicate with the respective manifolds. The manifolds accommodate pipes-distributors for supply/discharge of liquid. Insertion pieces are installed on both sides between the plates for hermetic sealing of the heat exchanger. The outlet of the second heat exchange system communicates with the inlet manifold of the hot well, the outlet manifold of the hot well communicates with the inlet of the cooling system of the gas heat generator, whose outlet communicates with the inlet of the first heat exchange system. The inlet of the second heat exchange system and the outlet of the first heat exchange system are intended for connection of the heat demand. EFFECT: enhanced reliability, ecological purity and efficiency. 12 dwg
