Big Box biochar kilns are an alternative to open pile burning that allows for in-woods biochar production in a simple metal box with no moving parts. This approach is based on technology used by charcoal makers for centuries but with a modern, mechanized approach. A mini-excavator or other piece of machinery is used to load, tend, and empty the kilns. This article will outline Big Box biochar kiln best practices, including the design, transportation, placement, loading, lighting, quenching, and dumping procedures for beginners developing their own Big Box biochar kiln programs. Biochar production requires a low oxygen burning environment, and the Big Box kilns use a flame-cap (sometimes referred to as a flame-curtain) method to burn material with limited smoke production. These kilns have been designed to be easily transferred to the site using an adequately rated trailer. A mini-excavator or other piece of machinery is used to load, tend, and empty the kilns. The author is not aware of a more accessible means for people to sequester durable carbon on the farm, ranch, or in the backyard. This article outlines Big Box biochar kiln best practices, including the design, transportation, placement, loading, lighting, quenching, and dumping procedures for beginners developing their own Big Box biochar kiln programs.
大型箱式生物炭窑是一种替代露天堆烧的方法，它能在一个没有活动部件的简单金属箱内进行林地生物炭生产。这种方法基于木炭制造商使用了几个世纪的技术，但采用了现代机械化方式。使用小型挖掘机或其他机械设备来装载、照料和清空窑炉。本文将概述大型箱式生物炭窑的最佳实践，包括为开展自己的大型箱式生物炭窑项目的初学者介绍设计、运输、放置、装载、点火、熄火和倾倒程序。生物炭生产需要低氧燃烧环境，大型箱式窑炉采用火焰帽（有时称为火焰幕）方法燃烧材料，产生的烟雾有限。这些窑炉设计为使用额定载重足够的拖车轻松转移到场地。使用小型挖掘机或其他机械设备来装载、照料和清空窑炉。作者不知道对于人们来说，在农场、牧场或后院封存持久性碳还有更便捷的方法。本文概述大型箱式生物炭窑的最佳实践，包括为开展自己的大型箱式生物炭窑项目的初学者介绍设计、运输、放置、装载、点火、熄火和倾倒程序。
