Parapet boilers Eurotherm KT TSY/TBY

Eurotherm KT TSY(P2) and KT TBY(P2) parapet coppers are intended for heat supply of individual houses, apartments and constructions of household purpose supplied with natural or simulated thermal medium circulation water heating systems with up to 0,2 PA (2 bars) of water working pressure and up to 90 C maximum water temperature on escaping from the copper.

KT TSY(P2) domestic parapet boilers with steel heat recovery system are used for water heating in water heating systems.  KT TВY(P2) double-loop parapet boilers with steel heat recovery system are used for water heating in water heating systems and water heating for hot water supply systems (with copper heat recovery system’s bypass duct). By placing main body’s special design copper exchanger into water cavity it is possible to produce hot water for household needs. Copper heat recovery system’s thermal capacity does not exceed the unit’s nominal heat output.

The KT TBY(P2) unit’s installation drawings are shown in figs 1..2. The B1 and T3 branch pipes for KT TSY(P2) unit are absent.

  • T1.1 and T1.2 – heating system water inlet (direct water) to the left and to the right respectively;
  • T2.1 and T2.2 – heating system water yield (return water) to the left and to the right respectively;
  • B1 – cold water input into GVS heat recovery system;
  • T3 – heated water yield from GVS heat recovery system;
  • G1 – low pressure natural gas inlet.

Devices are supplied in two “input and output” branch pipe couples of the heating system’s heat carrier – to the left and the right accordingly. One couple of branch pipes to the left or to the right can be blanked off by the screw plug. It is possible to connect two approximately equivalent independent heating system branches by the design decision confirmation to the device. In that case, it is necessary to install two pump components after T1.1 and T 1.2.branch pipes, at heating system forced circulation realization.

DESIGN PECULIARITIES

Devices consist of such main parts:

  • heat recovery systems with furnace and combustion products’ intake tank;
  • copper heat heat recovery systems (only for KT TBY(P2) devices);
  • gas-oil unit with autogenous automatic equipment;
  • decoratory case;
  • air duct;
  • chimney;
  • wind-shelter case.

The device’s major components, parts and details are presented in figure 3

The device, executed in form box-type structure form, is intended for floor-level installation near the outer wall. All device’s basic elements are installeded on the steel heat recovery system which structurally unites: fire-tube heat recovery system 1, furnace 2, combustion products’ intake tank 3, gas fuel unit 4 representing frontal sheet 5 with: flame-igniter unit 6 , gas collecting main 7 and autogenous automatic equipment 8 , fixed on the heat recovery system’s forward wall. The device’s decoratory enclosure group consists of side 9, forward 10 and upper walls 11 . Gas fixture’s governing bodies are removed through the upper wall into its front end. The governing bodies with an open cosmetic cover are provided in figure 3 (top view). The branch pipes 12 and 13 are removed by device’s corresponding elements for outer heating pipelines’ connection to the device.

The design has provided an opportunity for both right and left connection for heating system pipelines connection convenience, at the same time. Wherefore there are screwed nozzles on both sides. Either all four branch pipes, or less can be involved. Depending on heating system design. The uninvolved branch pipes needed to be muffled, however. The GVS contour сonnection pipelines is made only on one hand. Through branch pipes 14, 15.

The air intake duct 16 and combustion products’ disposal duct 17 are executed in the interpretation form, allowing to remove them through 250 to 600 mm thick outer wall . The wind-shelter case 18 fastens from the outer side of a wall, promoting combustion products withdrawal on the street and air intake for burning from the street steadily. The design provides normal burning process at up to 16 m/s air flow speed.
