Portable kiln
ActiveUS7458809B2Limited range of activitiesChamber furnacesFurnace cooling arrangementsEngineeringMechanical engineering
A portable kiln has a set of wheels, a handle and a platform base. The wheels and the handle are attached on a first side of the kiln so that the kiln can be tilted and rolled on the wheels using the handle. The platform base provides a spaced distance between the wheels and the floor when the kiln is sitting upright in an operational position. The kiln may also include a metal outer shell wrapped about an oven portion. The outer shell has a shell sidewall radially spaced from the oven portion sidewall, which forms an annular air channel between the outer shell sidewall and the oven portion. The outer shell has a C-shaped cross-section and it has upper and lower vent openings for the air channel. A hinge assembly allows a lid of the kiln to rest in an open position.

There is provided a top-firing hot blast stove capable of enhancing combustion efficiency in burner system, supplying high-temperature combustion gas to an entire checker chamber, and suppressing damage on a refractory material on an inner wall of a burner duct.A top-firing hot blast stove 10 has a burner system including: a burner 1 for passing fuel gas or combustion air to each of three or more pipe lines in a multiple pipe line structure; and a burner duct 2. A core pipe line 1b and a central pipe line 1c include a swirling flow generating means provided for generating a swirling flow of the fuel gas or the combustion air, while an outermost pipe line 1d carries a linear flow of the fuel gas or the combustion air, so that combustion gas HG including a linear component HG″ and a swirling component HG′ is generated in the burner duct 2. The combustion gas HG is supplied to a combustion chamber 3 from at least one or more of the burner systems in an inflow direction which does not pass through a center position of the combustion chamber 3.
