Definitions

  • the present invention generally relates to a supply air control device for a heater, and more particularly to a supply air control device for controlling primary air and / or secondary air for a heater such as a furnace.
  • heaters in which combustibles can be burned, known, such as tiled stoves, stoves, pellet stoves and central heating systems, which may also be partially mixed forms of the aforementioned ovens.
  • the aforementioned air supply control requires a separate control device each for primary air and secondary air.
  • the aforementioned control of the air supply - in particular the above-mentioned slider - also requires an attentive user who operates the controller by hand. This presupposes, in addition to a certain knowledge of the user on the relationship between combustion and primary and secondary air supply and the presence and the user becoming active. However, this is not desirable. In particular, in kilns, such as log burning stoves, a controller that allows automated control of the air supply is advantageous.
  • the object of the present invention is to provide an improved supply air control device.
  • the present invention provides a Zu poverty horrinvorlatin for a kiln, wherein the Zu poverty horrvorlatin an air supply, is introduced through the supply air in the Zu poverty horrvorlatin, a primary air opening, can be discharged by the supply air as the primary air from the Zu poverty horrvorlatin, a secondary air opening, through the Supply air are discharged as secondary air from the supply air control device, and comprises a first and a second control element.
  • the supply air is discharged as a function of a rotation of at least one control element as primary air and / or as secondary air through the primary air opening or secondary air opening.
  • the present invention provides a combustion furnace for combustion of a fuel, the furnace including a combustion chamber and a supply air control device that controls primary air and secondary air supplied for combustion of the fuel in the combustion chamber.
  • Fig. 1 an embodiment of a Zu poverty horrinvoroplasty is illustrated in accordance with the present invention.
  • ovens or kilns which are used as fuel
  • use wood in various embodiments.
  • kilns differ in their purpose.
  • kilns have the sole purpose of generating heat in a living space.
  • other furnaces additionally include, for example, a baking compartment and some even serve as central heating.
  • any mixed forms are realized again.
  • a stoves which includes a transparent panel on its front and thus serves as an eye-catcher in a living room and is also still water leading to serve as a central heating and possibly even used pellets as fuel, so that the fuel supply can run largely automated.
  • biomass burning means used such as wood in the form of logs, wood waste, which are pressed into pellets, for example, but also wood briquettes, coarse chippings, finely chopped, shredded or Halmgutpellets.
  • an important factor is the air supply.
  • air is taken from the room air surrounding a kiln.
  • the air supplied comes from an unfinished space, for example, from outside a house, that is, from the "outdoors".
  • the combustion of fuels, especially biomass has various effects.
  • the quality of a fuel may vary due to different types of fuel - as is the case, for example, with different types of wood - or the quality of the fuel may vary within one type of fuel - such as pellets made from pressed wood waste. Therefore, it is necessary to adjust the air supply for the kiln to the fuel accordingly.
  • the burning (burning) of fuel is also influenced by the introduction of the fuel and the arrangement of the fuel in a combustion chamber of a kiln.
  • a combustion of stacked logs in a combustion chamber is different than the combustion of pellets in a pellet stove, in which the pellets are also automatically replenished.
  • a firing process typically has different firing phases. For example, there is an ignition phase in which firing agents are set on fire, then a stable firing phase in which existing fuel is burned, possibly a "refill phase" in which new fuel is replenished - ie where in the combustion chamber burned, burned, glowing and unburned Combustant co-exists - and a burn-out phase in the fuel should burn completely to ashes. Logically, the temperature of the fuel, the corresponding flame, and the combustion chamber of the furnace and the air in the combustion chamber is different. Accordingly, it is desirable for each individual situation to control the supply of air to the firing process accordingly.
  • a fuel such as a log or wood pellets, or even other fuels consisting of biomass
  • a gasification of fuel i) burnout of the fuel gases.
  • the gasification of fuel is in some embodiments on a combustion grate which is arranged in a lower part of the kiln. On this combustion grate fuel is arranged. This fuel is set on fire. By burning the fuel not only the fuel is first converted into embers and then into ashes, but it also caused by the high temperature of the fuel gases that should be burned in the course of optimal combustion. This creates two areas during combustion - a lower one in which the fuel itself burns and glows and an upper one in which the rising gases are burned. In some embodiments, these areas are supplied individually with appropriate air. The lower area with primary air and the upper area where the combustion gases burn, with secondary air, which promotes optimal combustion.
  • a different supply of the combustion process with primary and secondary air results from the above aspects. So it makes sense, for example, in the ignition phase of the fuel, primarily to supply primary air, so that the fuel is quickly set on fire and reaches a high temperature. If the fuel burns once, the primary air supply should only be so good that the burning process is kept alive, otherwise too strong supply the fuel is burned too fast and the resulting heat primarily to the flue gas resulting from the combustion and is no longer delivered to the environment or, for example, a water-bearing heat exchanger. For this it makes sense to adjust the secondary air supply according to the combustion. Of course, depending on the fuel and combustion phase, any combination of primary air supply and secondary air supply is desirable.

  • temperature sensors for example, in the flue gas duct, but also in a supply air duct and / or in a primary air duct and secondary air duct can be attached.
  • at least one of said sensors may be present, which then corresponding parameters to the electronic Supply control so that this causes the distribution of the supply air in the primary air and secondary air accordingly. This is done for example by sending appropriate control signals to an electric motor drive, which then brings a rotor of the supply air control device in a position (rotational position), so that the desired ratio of primary air to secondary air is achieved.
