在我国，龙窑的历史悠久，其应用遍及明代以前南方主要产瓷省份，如江苏、浙江、福建、广东、江西和湖南等地。龙窑之所以得名，是因为其结构多倾斜于山坡或土堆上，与地平线形成10至20度的角度，外观酷似龙状，因此被称为龙窑，又称横焰窑。这些陶瓷工艺设施通常具备50至150立方米的容积，长30至80米，宽1.5至2.5米，高1.6至2米。在沿着窑道两侧分布有若干投柴孔或出入点供燃料松柴使用。而烟囱设计相对低矮，只需一米高，并且通道狭小，上下温差较大，这使得龙窑的建设成本显著低廉。

dragon kiln, with its history dating back to the Ming dynasty in China, was widely adopted in major ceramic-producing regions such as Jiangsu, Zhejiang, Fujian, Guangdong, Jiangxi and Hunan before that time. The name "dragon kiln" comes from the fact that these structures are often built on slopes or mounds of earth at an angle of 10-20 degrees relative to the horizon, resembling a dragon's shape.

The typical dimensions of a dragon kiln include a volume ranging from 50 to 150 cubic meters and lengths varying between 30 and 80 meters with internal widths of approximately 1.5-2.5 meters and heights measuring around 1.6-2 meters respectively.

Along both sides of the kiln tunnel are several openings for fuel loading or exit points where softwood is used as fuel for firing ceramics in this ancient process.

Notably low-profile smoke stacks measure only about one meter high while access routes within the structure are narrow due to large temperature differences between upper and lower sections which makes it more challenging for automation processes but offers relatively low construction costs compared to other types like reverse flow kilns whose efficiency is slightly higher than those found here; however there exists some drawbacks when using these systems - labor requirements remain quite high throughout installation & removal phases together with difficulties encountered during maintenance tasks leading users towards seeking better solutions like modernized versions offering greater convenience at affordable prices by leveraging technology advancements!
