A combustion chamber, having an upper part and a lower part, may include an annular constriction, in combination with the combustion chamber, to aid in directing partially combusted gases such as carbon monoxide away from the periphery of the combustion chamber back toward its center, and into the flame front. The annular constriction may also impede the flow of partially combusted gases located at the periphery, thus increasing the time these gases spend within the combustion chamber and increasing the likelihood that any products of incomplete combustion will undergo combustion. The combustion chamber may further comprise a dual burner cooktop for directing combustion gases and exhaust to multiple cooking vessels. In further embodiments, the combustion chamber may be made of, lined, or clad with a metal alloy comprising iron, chromium, and aluminum.

The invention relates to a wet process for building a 3t intermediate frequency electric furnace. By the process, 3t of materials can be melted, and the service life is prolonged. The process comprises the following steps of: (1) manufacturing a steel crucible die which has a shape of a truncated hollow cone; (2) paving an insulation layer and a thermal insulation layer by using two layers of asbestos cloth; (3) paving a furnace bottom, namely paving two layers of asbestos cloth at the furnace bottom in a staggered mode; (4) paving a furnace wall, namely paving two layers of asbestos cloth next to the inner wall of an induction coil from top to bottom, ensuring that each layer is flat and does not have any wrinkle, adhering longitudinal joints for lapping by using water glass, staggering joints of two adjacent layers, and adhering the asbestos cloth which stretches out of the upper plane to a fireproof brick plane at an upper opening of the furnace by using the water glass; (5) preparing a furnace lining material from refined quartz sand; (6) manually knotting a furnace lining, brushing a layer of water glass before filling, and tamping a filler; and (7) baking the furnace and sintering, namely baking only by using firewood after the furnace is built by the wet process, adding 50 to 60kg of firewood into a hearth for several times, and completely combusting to bake the furnace lining.

The invention provides a heating method for controlling decarburization in a heavy rail billet furnace in a heat accumulation heating mode. The heating process comprises a pre-heating section, a heating section and a soaking section. A furnace pressure measurement point is positioned at the pre-heating section; the full furnace is controlled at positive pressure; when the billet temperature is controlled to be less than 1,000 DEG C, the atmosphere in the furnace is oxidizing atmosphere, and the air consumption coefficient is between 1.05 and 1.25; and when the billet temperature is controlledto be more than or equal to 1,000 DEG C, the atmosphere in the furnace is weak reducing atmosphere, the air consumption coefficient is between 0.9 and 1.0. Aiming at the operation and decarburizationcharacteristics of the heat accumulation heating furnace different from the traditional heating furnace, the segment control method is adopted on the control aspects of atmosphere in the furnace and temperature, and a limit low-oxygen concentration burning process is realized. The method has the advantages of low heated billet surface decarburization, low oxidized burning loss, high furnace energy utilization, low pollutant discharge, low production cost and the like, is simple, convenient and feasible, and can achieve good effect of saving materials and energy at the same time of improving the heating quality of products.
