Fireplace insert for the even burning of wood or briquettes

Abstract

Comprising at least two adjacent chambers for the upright storage of solid fuels, lateral wall or guide elements for the lateral delimitation of the chambers, and at least two elongated support elements, characterized in that the support elements are arranged below the fuels and support them point- or line-shaped above the combustion chamber floor, so that ash can fall downwards, and that the distance between the lateral wall or guide elements is variable to adapt to different fuel dimensions.

Description

1. Technical field

[0001] The invention relates to a device for use in combustion chambers of solid fuel heating appliances, in particular wood-burning stoves, fireplaces or workshop stoves. The device serves to hold and position fuel materials such as logs or briquettes in order to ensure controlled and even combustion. 2. State of the art

[0002] In conventional combustion chambers, the fuel is usually placed loosely on the floor or a fixed grate. This has the disadvantage that the fuel can shift uncontrollably or collapse during the combustion process. This often hinders air circulation between the individual pieces of fuel, leading to incomplete combustion and increased soot formation. Furthermore, existing supports are usually rigid and cannot be adjusted to different fuel sizes (e.g., narrow wood briquettes vs. thick logs). 3. Object of the invention

[0003] The invention is based on the objective of creating a fireplace insert that: • Securely holds fuel materials in an optimal position, regardless of their shape and size, • enables stepless adjustment to the respective fuel, • improves primary and secondary air circulation in the combustion chamber, • does not hinder the removal of the ash and is easy to clean. 4. Solution to the problem and advantages

[0004] The problem is solved by a modular fireplace insert consisting of at least two parallel, vertical mounting plates. These plates are connected to each other via horizontally running threaded rods.

[0005] The advantages of the invention are: • Variability: The clear width between the plates can be continuously adjusted by screwing them onto threaded rods. • Improved combustion: The fuel is held upright or fixed in such a way that air can flow in from all sides (including from below). • Material flexibility: Depending on the requirements, the mounting plates can be made of fireclay (heat storage), stainless steel (durability) or other refractory materials. • Ease of maintenance: The open design allows ash to fall freely into the ash pan. The device can also be easily removed and cleaned. 6. Detailed description of an exemplary implementation

[0006] In a preferred embodiment, the device consists of three fireclay plates. Each plate has holes through which the threaded rods are inserted. The plates are secured to the rods by means of nuts. By simply sliding the nuts along the threads, the distance between the plates can be changed to create, for example, two narrow channels for briquettes or one wide channel for heavy logs. 1-16 = Nuts and washers A, B, C, D = Threaded rods E, F, G = Depending on the material used: firebricks, stainless steel plates or other refractory materials. Available in various sizes. Standard: Height 18cm, depth 20cm and width 3cm, in fireclay version. Standard: Height 18cm, depth 20cm and width 1cm, in stainless steel. H and I = combustion chambers Adjustable between 8cm and 15cm using the threaded rods
