Q:What should a charcoal coffee look like?: A cup of coffee is a Japanese division of a single product, refers to a taste, almost no acid, strong coke and bitter taste, taste is relatively strong. Authentic coffee is commonly used in carbon fire roasts (gas, carbon baking divided fire and infrared), color is black, taste fragrant and mellow, taste does not feel acid, if add some also have a flavor.

Q:What is the standard of coal: glossRefers to the reflection of the surface of coal under ordinary light. Asphalt, glass and diamond luster. The higher the degree of coalification, the stronger the luster; the more mineral content, the darker the luster; the deeper the wind and oxidation, the darker the luster, until completely disappear.

Q:Activated carbon can be reused?: Activated carbon can be activated by exposure.Exposure to activated carbon internal air has a thermal expansion and contraction effect, by exposure to air volume becomes larger, thus crowding out toxic substances and odor molecules. So to achieve the "activation" effect. It is not just another piece of land can direct the sun on the line, but this is the premise condition, there are some small details need to pay attention to, otherwise it would be self defeating.

Q:Coal and carbon is one thing, what is the difference?: Chemical composition:The organic matter in coal is high polymer complex organic compounds, mainly composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus and other elements, and more than three carbon, hydrogen and oxygen and total organic matter occupies 95%; inorganic matter in coal also contains carbon, hydrogen, oxygen, sulfur and other elements of a few. Carbon is the most important component in coal, and its content increases with the degree of coalification. The content of carbon in peat is 50% ~ 60%, the lignite is from 60% to 70%, the bituminous coal is from 74% to 92%, and the anthracite is from 90% to 98%. Sulfur in coal is the most harmful chemical component. Coal combustion, in which sulfur generated SO2, corrosion of metal equipment, pollution of the environment. The content of sulfur in coal can be divided into 5 levels: high, greater than 4%; sulfur rich coal, from 2.5% to 4%; sulfur in coal, from 1.5% to 2.5%; low sulfur coal is 1% ~ 1.5%; ultra low sulfur coal, less than or equal to 1%. Sulfur in coal can be divided into two categories: organic sulfur and inorganic sulfur.

Q: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".

Q:What is the role of circulating fluidized bed boiler in coal - fired air system?: : 1) to ensure the hot flue gas channeling but.2 furnace) to spread to the coal machine down coal can better into the hearth inside

Q:What is the meaning of coal m40.m10: Index of coke:The breaking strength of coke refers to the ability of coke to resist the impact of external shocks and not crack or defect along the structure, with M40 value;The abrasion resistance of coke is the ability of coke to resist the external friction force and not to produce the surface glass to form the debris or powder.

Q:How to get charcoal: 3 and then there is the burning of the trees, and after the destruction of the charcoal.This is the tree after the burning, the ax to get access to charcoal and the chance to get trees.

Q:Coal water slurry is used for what?: Coal slurry: is a new, efficient and clean coal based fuel, is a new member of the family of fuel, it is a mixture of 65%-70% of different size distribution of coal, 29-34% or 1% of the chemical additives made of water. Through the multi-channel rigorous process, sieve to the combustion of coal and other ingredients can not be burned, only to retain the essence of carbon to become the essence of coal water slurry. It has the same oil mobility, calorific value is equivalent to half of the oil, known as liquid coal products

Q:What is the structure of activated carbon?: Activated carbon is a black powder or granular amorphous carbon. The main components of activated carbon in addition to carbon and oxygen, hydrogen and other elements. Because of the irregular arrangement of the activated carbon on the structure, there are pores in the cross connection, and the carbon tissue defects will occur in the activation. Therefore, it is a kind of porous carbon, which has low bulk density and large specific surface area.
