How to solve the problem of coal spontaneous combustion
- Coal in the process of piling up spontaneous combustion occurs frequently, this is because the coal at room temperature will also be slow oxidation of oxygen in the air. Oxidation at the same time have a certain amount of heat, if the heat can not be dissipated, the heat in the coal heap together, temperature will rise, temperature and accelerate the oxidation of coal, when the temperature is higher than 60 DEG C when the coal temperature rises rapidly, if not timely treatment, it will cause a fire, this is the pile of coal only by self oxidation without external fire caused by the "spontaneous combustion" phenomenon. Prone to oxidation of lignite and long flame coal is more prone to spontaneous combustion".s
Bamboo charcoal package is valid
- Personally think that should still haveThe adsorption capacity was related to the particle size, and the adsorption rate of fine carbon was higher than that of the 80 mesh, while the bulk carbon was the slowest.Deodorant bamboo charcoal bag placed in the refrigerator, wardrobe, shoe cabinet, toilet, car and other places, every 2~3 months in the sun exposure once, you can get rid of bamboo charcoal adsorption of moisture and odor, to maintain a good function of bamboo charcoal. Charcoal bag placed more than one or two years, the demolition of the bamboo charcoal particles buried in the soil, used to improve soil activity, prevent the occurrence of pests and diseases, promoting plant growth.s

Other related to coal oil
- China has the advantage of coal to oil, but will not become the main direction of oil production experts believe that in China to engage in coal oil has a significant advantage. The rich coal less oil in recent years, with the development of economy, crude oil imports increased year by year, from 1993 to 2003 10 years, an average annual increase of more than 15%, import dependence is more and more high. 10 years, China's crude oil imports increased by 9.18 times a year to spend a lot of foreign exchange. Due to rising oil prices, in 2004 more than 55 billion yuan of imported crude oil last year. Therefore, experts believe that, from the strategic point of view of China's energy security, but also should strive to find ways to solve the problem of long-term supply of energy from the diversification, and coal oil is one of the feasible ways.s

What is lean coal, lean coal classification
- (2) lean coal (PM). Coal is a high degree of coalification coal, non caking or slight adhesion. No coking coking furnace. In the laminar flame, burning resistance.(3) lean coal (PS). Lean coal is a kind of high rank and low volatile bituminous coal and weakly caking. Typical coal coking, coking, coke powder are generated.(4) (SM). Coal coal is low volatile medium caking coking coal. Can produce a certain amount of colloid in coking. Separate coking, can get large blocks, crack less, shatter resistant better coke, but poor wear resistance of coke.s
