Wood Boiler BLAZE COMFORT

Advantages of gasification boiler BLAZE COMFORT

  1. PATENTED

    Mechanical detection of residual fuel

    This unique system provides automatic stable heat (embers), causing the fan to switch off when the level of the fuel decreases. This accurate detection maintains the hot embers layer in the combustion chamber for several hours, reducing the number of times a new fire is started in the boiler per season.

  2. PATENTED

    Protection against low- temperature corrosion

    The built-in thermostat with a temperature setting at 60°C and a special structure for mixing inside the boiler protects the boiler. Option of gravity connection to the buffer tank without pumps. Considerable savings during installation and safe operation. 7-year warranty on the boiler body, with no additional conditions. (optional accessory)

  3. PATENTED

    Three-way air supply

    Ensures uniform burning of fuel and allows to burn fuels of various dimensions (wood chips, sawdust, briquettes even lower quality). Pre-drying air, which is supplied (if necessary) into the upper part of the chamber will dry up any damp fuel in order to be able to burn it well and maintain high boiler efficiency and low emission values.

  4. Corrosion protection with an insulated compact hot chamber system

    Where the walls of the stoking chamber are not directly cooled by water – they are hotter, which prevents condensation. The service life of these boilers is many times longer than that of conventional gasification boilers. It also allows the combustion of moist fuel, without significantly reducing the boiler‘s service life. The increased temperature of the walls prevents the unpleasant deposition of tar in the stoking chamber. The compact gasification chamber is a separate element that is insulated from the walls of the water boiler. The chamber can be replaced.

  5. Inclined bottom of the gasification chamber

    Provides automatic ash removal from the combustion chamber during combustion, completely eliminating the need to clean it before firing it up again.

  6. Top boiler output adjustability

    Allows you to set the required boiler output in percentages and regulate the boiler with continuous operation. Setting reduced power will ensure a long period of combustion in the boiler, at a quality comparable to the quality at 100 % power.

Boiler with three-way combustion air supply

Boilers can easily control the distribution of the air entering the fuel (pre-drying air is supplied over the fuel). Therefore the boiler can be adapted to various fuels. This effectively burns fuel that can be easily burn (wood chips, small briquettes), but also fuels that burns hard (large logs, wet wood).

 

Three-way air supply control

Pre-drying aprimary air are open at 100 %, secondary air is completely closed. In this position you can find the air supply curtain in case of burning damp wood or big logs.

Secondary air is open at 100 %, pre-drying and primary air are completely closed. In this position you can find the air supply curtain in case of burning dry wood or briquettes, where is a need for bigger amount of secondary air for high quality combustion.

Primary and secondary air open at 50 %, pre- drying air completely closed. You can find the air supply curtain in this position during combustion of standard fuel.

SEMI-AUTOMATIC operation of the pyrolitic boiler

Stoking
After 8 hours
Up to 24 hours
After 24 hours
After short time

1

Stoking - after stoking fuel to whole volume of the stoking chamber the combustion time is up to 8 hours depends on the fuel type and preset boiler output.

2

After 8 hours - when the fuel level decrease under the detection threshold, then the sensor sends signal and controller switch off the fan. This stops the burning process.

3

Up to 24 hours from the first fuel stoking, there are still hot coals (embers) in the chamber, so it is sufficient to add directly bigger logs, start the fan and combustion continues.

4

After 24 hours and more after first fuel stoking there will not be hot coals (embers). There will remains fuel residual in the form of charcoal. In such a case is suifficient to start the fan and with small piece of paper fire up the layer of charcoal.

5

After short time the charcoal fires up very well. Then it is possible to add even larger pieces of wood. The residual fuel detection mechanism provides user‘s high operation comfort due to lack of new ignitions, when user must clean the boiler and cut small pieces of wood and wait until the boiler ignites successfully.

controller
ecoMAX

Automatická riadiaca jednotka ecoMAX 860

Sophisticated control software allows you to set the required boiler output in percentages and regulate the boiler with continuous operation at 50 % to 130 % of the nominal output. Setting the output to 50 % will ensure a long period of combustion in the boiler, at a quality comparable to the quality at 100 % power.

This solution allows the boiler to operate at a lower output (especially important in the transition period), as well as the installation of a smaller buffer tank, saving expenses and space.

The controller also evaluates the O&sub2; values measured by the lambda probe and controls the actuator of the primary, secondary, and pre-drying air curtain in order to maintain the set value of residual O&sub2;.

Controller's features:

  • boiler’s output regulation from 50 to 130 % of nominal output
  • exhaust fan control
  • modulating pellet burner output
  • pellet feeder control
  • boiler pump
  • HUW pump
  • HUW circulation pump
  • mixer pump
