Both electric and gas kilns are common for smaller scale production in industry and craft, handmade and sculptural work. Modern kilns include: Retort kiln: a type of kiln which can reach temperatures around 1,500 °C (2,700 °F) for extended periods of time. Typically, these kilns are used in industrial purposes, and feature movable charging ...
When operating, each kiln used 30 to 40 cords of Douglas fir wood per load, producing about 1,500 to 2,000 bushels (70 cubic meters) of charcoal over a two-day burn. The kiln operation lasted for less than three years, employing 150 to 200 people at its peak, and had a monthly output estimated at 44,000 to 50,000 bushels (1550 to 1762 cubic ...

The tars and smoke produced from carbonization, although not directly poisonous, may have long-term damaging effects on the respiratory system. Housing areas should, where possible, be located so that prevailing winds carry smoke from charcoal operations away from them and batteries of kilns should not be located in close proximity to housing ...
