Problems solved by technology

Although the existing secondary combustion chamber has an air supply system, it is only possible to manually adjust the amount of air charged, and it is impossible to achieve precise and quantitative oxygen supply adjustment.
As a result, in the process of replenishing air, either the oxygen content is too high to lower the indoor temperature, which is

Abstract

The invention discloses a secondary combustion air supplementation device for a biofuel combustion furnace. In order to completely combust a fuel and reduce harmful ingredients in flue gas produced by combustion to minimum values, an air supplementation device is additionally arranged at the front end of a secondary combustion chamber, and a high-accuracy oxygen content measurer is arranged at the tail end of the secondary combustion chamber. According to the device, an air supply passage and the opening of each passage valve can be automatically regulated according to oxygen content measured by the oxygen content measurer by the air supplementation device, so that the oxygen content in the flue gas can reach a reasonable control range.

Description

technical field [0001] The present invention generally relates to a biofuel combustion furnace, and in particular, relates to a secondary combustion gas supply device for a biofuel combustion furnace, and an improved biofuel combustion furnace using the above secondary combustion gas supply device. Background technique [0002] Through long-term production practice, people have realized that only by using hot air as the medium and carrier can the heat utilization rate and thermal work effect be greatly improved. As a thermal power mechanical hot blast stove, it began to be widely used in my country in the late 1970s. It has become a replacement product for electric heat sources and traditional steam power heat sources in many industries. The hot air stove is a universal hot air device, which can be used in conjunction with drying equipment for various materials. It is widely used in the drying of products in the fields of agriculture, chemical industry, fertilizer, feed, bui...
