1. Glaze melting pool

The glaze melting pool is composed of the bottom, sidewall, feeding mouth, burner and the lower part of the roof. It is not only the melting chamber of glaze but also the combustion chamber of fuel. Thus, the structure must not only meet the requirement of the glazed melting process, but also can ensure the complete combustion of the fuel and the complete release of the heat.

1) The bottom and sidewall

The bottom and sidewall are the main part of the melting pool. They are subjected to the most serious corrosion by glaze melt and flame. It is the key part that affects the service life of the furnace. Now the bottom and sidewall are mainly constructed with fire clay bricks. In order to expand the service life of the furnace, the following measures are taken:

① The bottom and sidewall as well as the parts in contact with the glaze melt can adopt high quality high alumina bricks and corundum mullite bricks.

② Within the permissible range of process conditions, try to increase the thickness of glaze on the bottom (60-80mm) to reduce the erosion of glaze melt to the bottom.

③ Try to adopt large refractory bricks to reduce joints since corrosion always start from the joints.

④ When constructing, be careful and narrow the joints. Try to adopt refractory mortar with high refractoriness and good corrosion resistance and fill up the joints of brickwork with mortar or cement.

The bottom is horizontally constructed or with 1% inclination gradient in the direction of discharging port. The latter is mainly used to melt antimony glaze.

Currently the bottom is generally 2.5-3.8m long and 1.1-1.6m wide. The radio of the length and width of the pool can be determined by the properties of batch materials and nozzle. If titanium glaze is melted and high pressure nozzle is adopted, the width can be smaller and the length can be larger. If antimony glaze is melted and low pressure nozzle is adopted, the length can be smaller while the width can be larger. The bottom can be 230-345mm.

The height of the sidewall is the height of the pool, generally with a length of 0.6-0.85m and a thickness of 345-390mm. In order to make the flame more focused, and reduces flow resistance of glaze melt, the discharge port can be arc-shaped.
