Natural gas kiln with combustion atmosphere control and method for burning Jian zhan bowl

Abstract

The invention relates to a natural gas kiln with combustion atmosphere control and a method for burning a Jian zhan bowl. The natural gas kiln comprises a furnace body, a furnace door, a natural gas combustion system, a sagger, a thermocouple and a PLC automatic control system. The natural gas combustion system is electrically connected with the thermocouple and the PLC automatic control system, the sagger is arranged in the furnace body and forms a closed space, natural gas feeding ports which are arranged in a penetrating mode are formed in the furnace body and the sagger, and the natural gas feeding ports are connected with the natural gas combustion system. The natural gas combustion system is adopted, the high efficiency and environmental protection are achieved, the temperature in the kiln is uniform, the sagger forms the closed space used for accommodating the Jian zhan bowl and further used for building a strong reducing atmosphere, and the technical problem that an existing natural gas kiln can not meet the reducing atmosphere is solved. According to the method for burning the Jian zhan bowl, the reducing atmosphere is controlled by injecting natural gas into the sagger during the reduction and burning process, the automatic control is realized through the temperature control system and the combustion atmosphere, and the production scale of the Jian zhan bowl is expanded.

Description

technical field [0001] The invention relates to the technical field of Jianzhan firing, in particular to a natural gas kiln with combustion atmosphere control and a method for firing Jianzhai. Background technique [0002] Jianzhan is one of the eight famous porcelains in my country. It is called Tianmu tea bowl in Japan, which means the black-glazed tea bowl fired in Jianyao, that is, Jianyao black-glazed teacup. Jian kiln is one of the eight famous kilns in my country. Its kiln-changing Jianzhan is a rare top-grade product. There are three extant kiln-changing Jianzhan products in the world, which are collected by Japan and listed as national treasures. Most of the black-glazed porcelain produced by Jian kilns in Song Dynasty were tea bowls, collectively called "Jianzhan". Jianzhan is a representative of black-glazed porcelain, which used to be the tea set used by the royal family in the Song Dynasty. According to the current research, Jianyao originated in the late Tang...

AI Technical Summary

Problems solved by technology

After on-site research on the use of electric kilns, it has the problem of low yield due to uneven temperature in the kiln, and is limited by power. The scale of electric kilns is generally small, and it is difficult to achieve industrial production.

[0004] The temperature inside the natural gas kiln is uniform, but the existing natural gas kiln cannot meet the demand due to the high requirements for the reducing atmosphere for the firing of the kiln. The method of firing Jianzhan
