TK2 cooker
Application
Tk2-610 coal-burning cookers are designed for boiling, frying and baking. The cookers are equipped with an oven, stationary grate, air flow to grate controller and flue gas circulation handle. A furnace, ash pit and oven doors are located in the cooker front wall. The oven has a protective insulation to ensure uniform interior heating and is equipped with a sheet-metal baking tray.
Tk2 coal-burning cookers are used in:
- households,
- detached houses,
- holiday cottages.

Tk2 cooker design
The furnace and flue gas circulation channels are lined with chamotte bricks and insulating plates. Depending upon the location of the flue gas outlet hole, so called left (L) and right (P) as well as non-walled and walled (with drawer) versions are produced. Depending upon his needs, the customer uses the standard execution (with back wall hole) or changes the flue gas direction himself by exchanging the flue gas outlet sheet (back, side) position and changing the pipe cap location. The cookers can also be equipped with heating insert located in the furnace chamber. At normal (10 Pa) chimney draught and burning rated coal amount of 1.6 kg/h the insert performance is as follows:
- thermal efficiency > 20%,
- thermal capacity > 2 200 W.
Appropriate cooker connection with a water heater enables warm water generation in amounts sufficient for one family with simultaneous cooking or baking in the oven as well as kitchen room heating. The connection of a central heating heater ensures heating for a >15 m3 room (e.g. bathroom) but at the expense of smaller amounts of warm water.
