HIGH DRAFT FAN MANUFACTURER-9927820899

High Draught Kiln technologies that are more energy efficient and cause lesser pollution.One such technology named fixed chimney Zig – Zag kiln .The Zig-Zag kiln or the High Draught  kiln is similar firing technologies with essential variations in brick setting patterns where the kiln basic structure remains same. The principle followed in this family of high draught kiln types is to prolong the travel path of fire. This high thermal efficiency of the kiln reduces fuel consumption by 25%. The earliest type of this technology was termed as Zig-Zag kiln and high draught kiln developed in the early 1900s. Various reforms were also built which were relatively inexpensive variants adopted by small brick manufacturers. The design of this type of kiln ensures continuous operation of the kiln.
One of the more developed variant was The Habla Kiln. It was essentially an arch less zig-zag kiln patented in 1920 by British Engineer A. Habla. This had very wide and continuous open firing channels. Unlike zig-zag variants there were no permanently built dividing walls. Thus, the energy savings were higher. However the most important aspect of this kiln was that bricks could be loaded into the firing spaces through vehicular movement.
In Asian countries of India, Nepal, Bangladesh and Pakistan the High Draught or HD Kiln is the most popular technology of Zig-Zag firing. Their difference with European variation is the absence of any dividing walls. In the European variety of HD kilns, the length of the kiln gallery is increased by zigzagging the chambers and the fire follows a zig-zag path instead of a straight path followed in BTK. In the early 1900s, these types of kilns were widely used in developed countries particularly in Germany and Australia. In Europe, the interior cross-section of the kiln used to be small in original zig-zag kilns (7.5 ft wide x 7.5 ft high) and the kiln used to have 16-20 chambers each 20-25 ft long. Fan draught was provided and the kiln operated on high draught at a very fast rate of fire travel (50-100 ft per day).
