A panel for simulating a firebox for use in an electric fireplace and an electric fireplace incorporating the same. The electric fireplace includes housing with a grate, a plurality of artificial firelogs positioned on the grate and an ember bed positioned under the grate. A light source is positioned to transmit light through a plurality of apertures in a rotatable cylinder that is disposed rearwardly of the firelogs. The panel is a planar member that is positioned in the housing between the cylinder and the firelogs. The panel includes a pattern thereon which represents a firebox of a wood-burning fireplace. The pattern is formed by silk-screening, painting or etching a pattern of a flat wall of firebricks, a recessed wall of firebricks, stones, logs or any other markings that represent a firebox found in a fireplace. The light source preferably transmits light through flame-shaped apertures in the rotatable cylinder, thereby projecting flame-shaped images onto the panel or onto a screen that is positioned forwardly of the panel.

The invention relates to a technology of purple clay ware and particularly relates to a wood firing technology for purple clay ware, belonging to the technical field of purple clay ware firing. A finished product of purple clay ware is prepared by a series of steps such as throwing and drying, fettling and drying, glazing and drying and kiln loading and wood firing. In the invention, a reduction firing way is realized by adding wood into an electric kiln and replaces the way of wood firing in a gas-fired kiln in the prior art; more than 30% of reducing gas CO2 generated by wood burning in the kiln is adopted for strong reduction of iron oxide in the purple clay so that the purple clay ware has magnetism and ability of improving water quality; and meanwhile, purple clay ware with rich and bright colors can be formed without adding a coloring agent, and the artistic value of the purple clay ware is increased.

A method of ceramicizing a floated glass is provided where the glass ceramic material obtained thereby has high stability because of the special quality of the atmosphere in the ceramicizing process. The glass ceramics thus obtained have special surface properties that avoid crack formation. Thereby very high bending tensile strengths are achieved. These glass ceramics can be used as fire protection glass, hot plate of a cooker having a coating on the lower side, safety glass, panes of wood-burning fireplace inserts, in colored form as hot plate of a cooker, base plate, thermally resistant panel lining in furnaces and microwave facilities.

A Log Cartridge Burning System is provided comprising a simple, convenient and manageable wood burning system which can easily be applied for use to cook and heat. The log cartridge is comprised of a flammable body of compressed material and a bore formed and sealed by the use of a protective outer paperboard tube and a protective inner paperboard tube together with a top and bottom paperboard cover which serve to hold and maintain the integrity of the entire cartridge without the use of any wax binders. The flammable body of compressed material may be made partly or entirely from natural combustible materials such as sawdust or wheat hulls. The burn pot is specially designed to accommodate the log cartridge of the present invention. The log cartridge burning system can easily be utilized in a variety of appliances such as a patio heater or fireplace, barbecue or grill, or other cooking and heating appliances.

The heart of the “New Home Cooling Cycle” is a concrete heat exchanger located under the home. The heat exchanger is constructed of concrete and PVC piping. There are two flow passes. Each is ninety degrees from the other. On a hot sunny day, heat absorbed by air inside the home is routed through one pass of the heat exchanger where the heat is removed by absorption into the concrete, thus removing heat from the home. Air is circulated using a small electric blower. Air leaving the heat exchanger is cool and is returned to the home ready to absorb heat again. The recycled air absorbs additional heat and the cycle is repeated through the heat exchanger. Regeneration of the heat exchanger is accomplished at night. Cool night air is blown, using a small electric blower, through the heat exchanger second pass, ninety degrees to the absorbing pass. This cooling air absorbs heat from the heat exchanger and exhausts it back to the night air. The two heat exchanger passes are totally isolated to prevent moisture from entering the house circuit. This same cycle is used during winter. On a sunny winter day, solar heat and heat from a wood burning fireplace is absorbed by air inside the home and is routed through the heat exchanger as in the summer cooling cycle. Heat is removed and stored in the heat exchanger and cooled air is returned to the home where the cycle repeats. At night, heat stored in the heat exchanger is routed into the home. During winter, there is no regeneration required for the heat exchanger. Usage of refrigerated air conditioning is radically reduced. In some United States climates, it may be possible to eliminate refrigerated air conditioning.

The invention discloses a preparation method of a pottery pot. According to the preparation method of the pottery pot, Longshan Wuyuan river red clay and Chinese medical stone are used as raw materials and are appropriately proportioned; the production process of Longshan Degong black pottery is adopted, the processes of clay fermentation, vacuum pugging, moulding by throwing, polishing and sculpturing, engraving and calendering, shade drying and grinding and wood burning are adopted, and the techniques of pottery firing, fuming and carburizing through pine branches and pine leafs by Longshanancestors 4,600 years ago are adopted for reference, and the pottery pot is prepared through more than a dozen procedures and an all elaborately hand-crafted way. Through the preparation method, the wood burning process is adopted, natural kiln change is carried out, and the pottery pot is rich in mineral substance of calcium oxide, magnesium oxide, iron oxide, silicon oxide and trace element beneficial to human bodies and has the health care effect. Through the preparation method, the technical problems of the black pottery art water seepage, water avoidance and color difference are solved, the service life is prolonged, and the pottery pot is made high-end and elegant, and integrates the characteristics of being artistic, cultural, ornamental, practical and collectible, and accordingly people with the pottery pot can return to nature, enjoy nature, and prolong life.

An adjustable primary air supply for wood burning device comprises at least one but preferably two thermostatic bimetal elements which, by bending with temperature variations, directly actuate a flap that opens and closes the air entry opening. Primary Air is the air used to control the burn rate and it is adjusted in order to achieve the desired burn rates and Secondary Air is the air used to complete the combustion and is not adjustable. Using these two sources of air, the invention consists of a device, which allows the primary air supply to remain open until proper burning is established. Therefore, when the temperature of the appliance rises, the combustion air gradually decreases to its preset value by having the primary air supply automatically shut off as temperature increases. A higher temperature indicates that the wood is sufficiently hot to decompose into flammable gases, so only secondary air is required to continue the combustion process.

An industrial oven with tunnel for the baking of pizza or similar alimentary products is disclosed, made up of a bearing structure (10) in refractory material comprising an inlet mouth (40) and one of outlet (41) connected by a passing through tunnel (4) along which a baking surface (5) supporting pizza or similar alimentary products slides. Said oven is heated with firewood and it comprises slits (22, 24) for the passage of primary air for the combustion of the firewood and air for the oxidation of the excess smoke, said primary and secondary air being moved by fans (50) controlled by a control unit which processes data on the composition of the air detected inside the oven by sensors (26), a top combustion chamber (15) housing top furnaces (17) made up of top grates (18) supporting combustible firewood and a bottom combustion chamber (16) housing bottom furnaces (30) made up of bottom grates (31) supporting combustible firewood.
