Boiler construction - elements

Sealed wood gasification chamber - used simultaneously as a loading chamber. When appropriate amount of primary air supplied by the pressure fan is delivered, wood gas is generated
Nozzle - made of refractory concrete, mixes wood gases with the secondary air and a flammable mixture is produced that undergoes self-ignition at about 1000°F
Exhaust reheat space - the main combustion chamber, where temperature reaches about 2000°F serves as an ash pit
Smoke tube heat exchanger - (flue gas to water) heats up the installation water
Fan - linked to the microchip controller, monitoring the quality of the whole burning process
Safe guard thermostat - each boiler is equipped with an additional safe guard thermostat, which switches off the fan while the water gets up to 180°F

Boiler construction - materials

Boiler body - boiler casing is made of welded metal sheets that are 6mm thick, whereas the remaining walls are 4mm thick.
Heat exchanger - smoke tube heat exchanger made of tube with dimensions 57 x 4mm
Insulation - boiler thermal insulation is composed of glass wool of Nobasil 20mm thick, while the i external casing consists of metal sheet panels 0.8mm thick (powder painted)
Nozzle - ceramic element made of refractory concrete (working temp. up to 2100° F)
Chimney flap - made of high quality steel. Tight flap adhesion to the combustion duct assures the burning chamber tightness
Boiler regulator - placed on upper boiler cover. The regulator is fixed to the boiler cover by stuck catch
Chimney flue - made of 4mm steel tube
Ash pit - steel bottom of the burning chamber, ceramic ash pit added (working temp. 2100° F) and additionally covered by refractory concrete
Boiler door - produced of high quality steel, insulated with Nobasil thermal insulation and inside covered by refractory concrete layer.
Also protected with heat-resisting fiberglass cord.

Boiler sizeing

EKO-Line boilers may be used for heating any kind of building. They are mostly used in one-family houses, drying houses, workshops, halls, or greenhouses. However, boiler placement is not limited to these applications; the above are just examples of where EKO-Line boilers have worked with success.

Selecting a boiler that adequately fits ones output is very important. An improperly chosen boiler may subject the end-user to unnecessary expenses during boiler usage.

Boiler output should be based on a building’s heat demand, calculated by a qualified central heating designer. To select the appropriate boiler, the a/m calculated value should be increased by 20%. If this calculation isn't performed, boiler sizing may be chosen using the heat factor in relation to m3 of building cubature. Heat factor values should be determined as 30-50 W/m3 depending on heat insulation.

The scheme is only an example and New Horizon is not responsible for the wrong boiler choice.

RK 2001 UA Regulator

Downloads: Controller Instruction Manual

EKO-Line boilers are equipped with RK 2001 UA enabling:

Interaction with circulating pump,
Interaction with room temperature sensor, installed in the room and connected with the boiler regulator by two-strand wire
Modulation of fan rotation,
Boiler output adapting to actual weather conditions,
Interaction with EUROSTER room thermostat

Each boiler is able to work without room temperature sensor as well.
