What is orchid charcoal?

Published on: Nov 07, 2022

Speaking of orchid charcoal, the first thought of many people is "isn't it a black guy", but this "black guy" is not only clean, but also more comfortable and environmentally friendly when burning.

Blue charcoal is understood from the name, which is charcoal with a blue flame; from the perspective of performance characteristics, blue charcoal has the characteristics of high heat, low ash, fast heating, no smoke, low sulfur, low phosphorus, and low aluminum. "Solid Natural Gas".

Compared with ordinary coal, clean and environmental protection is the biggest advantage of blue carbon. Domestic authoritative institutions such as Tsinghua University, the Institute of Earth Environment of the Chinese Academy of Sciences, and the General Institute of Coal Science have conducted a lot of detailed research on the combustion emissions of Shenmu lan charcoal. The research results show that the three indicators of PM2.5, carcinogens, and haze-causing substances emitted by the combustion of high-quality blue charcoal have decreased by 93%, 92% and 98% respectively compared with clean coal, blue carbon is more than 97% lower than Shenmu clean coal; in terms of sulfur dioxide emissions, blue carbon is 57% lower than Shenmu clean coal.

Based on the 44.2404 million tons of coal used for civil and direct dispersal in the Beijing-Tianjin-Hebei region in 2013, if blue carbon is used to replace bituminous coal (calculated according to the positive energy blue carbon index), the emission of PM2.5 can be reduced by more than 500,000 tons only once , SO2 can be reduced emissions by about 250,000 tons; If blue carbon is used to replace high-quality anthracite, the emission of PM2.5 can be reduced by nearly 1/2, and the emission of SO2 can be reduced by about 200,000 to 400,000 tons. If blue carbon is used to replace high-quality anthracite coal, the emission of PAHs can be reduced by about 60,000 to 80,000 tons.

On October 22, 2016, the Ministry of Environmental Protection of the People's Republic of China officially released the Technical Guidelines for Comprehensive Treatment of Pollution from Civil Coal Combustion (for Trial Implementation) (hereinafter referred to as the Guidelines).

In the "Guidelines" on "comprehensive treatment technology of civil coal-fired pollution", five types of clean energy replacement, high-quality coal replacement, energy-saving and environmentally friendly coal-fired stoves, central heating, and building energy saving are specified.

Among them, in the "replacement of high-quality coal", it is required that "areas with abundant coal resources, good economic conditions and serious pollution should give priority to high-quality anthracite, briquette, blue carbon and civil coke with low sulfur and low volatile content". Since then, blue charcoal has been officially included in the category of high-quality coal by the Ministry of Environmental Protection and promoted to control the pollution of civil coal combustion, which marks the official opening of the clean application market of blue charcoal.

Xie Kechang, an academician of the Chinese Academy of Engineering, said: "Clean coal is clean energy." Blue charcoal is converted from coal, but it is no longer coal, it is a real clean energy. So is it clean to use? Is the emission pollution big? Is it useful or not? Save money? Don't look at the emissions, this is the last word.

In recent years, in response to the serious environmental pollution of the northern civil scattered coal heating, as a clean fuel, orchid charcoal has been widely used in the civil field in North China, replacing the scattered coal heating, which is known as a sharp weapon to control smog!
