AI Technical Summary
Existing cooking and washing kettles lack efficient heat distribution and ash precipitation mechanisms, leading to uneven heating and ash accumulation, which complicates cleaning and maintenance.
A cooking kettle furnace with a heat storage body at its annular base featuring radial recesses and offset slots, allowing for even gas distribution and ash precipitation, combined with asbestos cords to prevent food overflow and ash escape, and a refractory masonry design for easy cleaning.
Ensures even heat distribution, prevents ash accumulation, and facilitates easy cleaning, enhancing the efficiency and maintenance of the cooking process.
Description
[0001] Cooking and washing boiler stove In cooking and washing boiler stoves, it is already known to incorporate a boiler-enclosing element into the stove casing and to use a supporting heat storage body to allow cooking to continue even if the fire sags or goes out, thanks to the radiant heat of the to enable storage body.
[0002] The invention relates to a device for boiling laundry and liquids, boiling oils, melting fats, resins etc. boiler furnace serving, in which the heat storage body is attached to its ring-shaped lower part supporting the boiler with radial It has recesses and slots offset from these recesses along its upper edge. This is intended to ensure a uniform Distribution of the combustion gases around the boiler and precipitation of the fly ash are achieved. - The boiler furnace according to the invention is in a The embodiment is shown in the drawing, namely: Fig. t shows a longitudinal section and Fig. 2 a cross-section through the oven along line A- B of Fig. r. _ A heat storage element .I, forming a hollow cylinder, is installed in the furnace casing in such a way that both between the Oven casing and storage body as well as between the storage body and the inserted cooking kettle f ring-shaped flues for passage the flue gases remain free. The storage body is fitted all around its lower part, which contacts the boiler bottom, with radial studs at equal intervals. The upper edge is provided with recesses and slots offset from these recesses. While the lower boundary... The slots are designed in a saddle shape to prevent ash deposits; the recesses are formed by sloping surfaces. limited.
[0003] If a fire is lit on the laterally installed grate a, the heating gases from the combustion chamber p pass by the support pillars et through the recesses e into the annular channel g, they flow around the boiler and emerge through the staggered, pillar-bounded il The flue passes into the annular channel k, and finally exits through the flue m, which can be closed by means of a sliding gate, into the chimney iz. The flue then... The offset arrangement of the lower boiler support pillars e1 and the upper support pillars il forces the flames to swirl and stagnate, as well as to Precipitation of the entrained solid fuel and fly ash particles.
[0004] Asbestos cords are inserted into the annular space between the upper part of the cooking kettle and the stove ceiling, which prevent that overflowing food flows through the inner firebox g into the combustion chamber p and the heating gases escape from the flue o to the outside. Asbestos cords also create a balance between the greater expansion capacity of the metal and your fireclay brickwork, thus ensuring its freedom from cracking.
[0005] Cleaning openings with sweeping boxes 1 serve for easy cleaning of the walls of the firebox k. The remaining surfaces, onto which To prevent fly ash or soot buildup, a thorough cleaning can be carried out through the combustion openings or after lifting out the boiler. will be cleaned.
[0006] The furnace masonry consists of highly refractory, perforated clay bricks mixed with chamotte of the same head size, but of varying lengths, mortared with fireclay mortar and jointed on the outside with cement mortar. The mortar joints allow for compensation of the to counteract thermal stresses caused by the heating of the masonry and prevent cracking in the same.
