Circulating water agents are not widely used in cement-based waste thermal energy production. After all, the installed capacity of residual thermal power generation is not very large, usually around 3 MW. Therefore, the circulating water volume of the circulating water system is relatively. According to nearly 20 years of "Xingerui", judging from years of experience, the amount of circulating water treatment chemicals used in waste cement thermal power generation is about 10 W, or even less.
The formula for calculating the production cost of float glass is as follows.
Glass Cost Accounting Fuel and soda ash costs are the two largest cost elements in glass manufacturing. The yield of flat glass is generally around 90%, and the remaining 10% of broken glass is used for recycling. The capeAnnual production capacity of the industry (heavy boxes) is generally calculated as daily volume (tons/day) * 6,000, and one ton is equivalent to 20 heavy boxes (one heavy box is equivalent to 50 kilograms). Preliminary calculations show that each box of flat float glass consumes approximately 10 to 11 kilograms of heavy sodium carbonate, which is equivalent to 0.2 to 0.22 tons of sodium carbonate to produce one ton of float glass per day; It takes 0.185 tonnes of heavy oil to produce one tonne of glass. Heavy sodium carbonate generally uses crude salt and limestone as raw materials, produces light sodium carbonate by chemical synthesis, and then produces heavy sodium carbonate by solid phase hydration. In addition, heavy sodium carbonate can also be obtained by evaporation or carbonization using trona as raw material. Petroleum coke: One ton of glass uses 0.18 to 0.22 tons of coke.e oil, with an average of around 0.2 tonnes. The current list price of medium sulfur coke in the market is about 1,100 yuan/ton, and the price of low sulfur coke is about 1,100 yuan/ton. coke costs about 1,500 yuan/ton. Recently, due to the importance of environmental protection, medium sulfur coke has become mainstream, while high sulfur coke has basically withdrawn from the market. Natural gas: Natural gas in southern China costs 3.8 m/yuan, and a ton of glass in southern China requires about 200 m/yuan. The gas price in Shahe area is around 3.05 yuan/m² (note that the price will change). Coal-gas: Coal-gas is mainly used in Shahe, North East and North West. The Shahe region uses more than 6,000 kcal of lump coal to produce coal to gas. Since the byproducts of the modified process include carbon black, waste thermal energy production and other factors, a single ton of glass requires about 0.35-0.4 tons of lump coal.
