The boiler of paper mill is generally quick loading boiler, and the design efficiency is generally between 75% - 82%. However, the efficiency of fast loading boilers generally decreases by about 15% after 5 years of use (due to scaling and insulation). Therefore, we calculate the boiler efficiency as 70% - 75%, and my value is somewhat conservative. At present, paper mills generally do not have pulping process, and the steam consumption is relatively stable. As for whether it is enough or not, it depends on the requirements of paper equipment suppliers. Steam calorific value refers to the saturated steam temperature, which must be the theoretical value.
A 10 ton boiler with a calorific value of 5000kcl / kg of coal
The calorific value of a ton of coal is 5000kcl * 1000 = 5000000kcl.
The average thermal efficiency of the boiler is 70%. Then the available calorific value is: 5000000 * 70% = 3500000kcl
The calorific value of one ton of steam is 600000kcl
Steam output per ton of coal: 3500000 / 600000 = 5.83 tons
