1 Scope
YS/T 124 This part provides thermal balance determination carbon products manufacturing various types of tank calciner and calculation basis, measuring strip Member, measurement items and calculation methods.
This section applies to the production of various types of carbon products tank calciner Determination and calculation of heat balance.
2 Measurement system
Measurement system for the tank firing furnace body, including the top charging port; spout cooling water jacket; the flue outlet.
3 Determination of requirements and time
3.1 in the tank firing furnace heat balance measurement cycle, tank furnace production capacity to meet the design production, normal operation, the operation of the furnace thermal parameters the number of stable conditions for the best case, as the measurement time.
3.2 Determination of time of not less than a predetermined continuous 6h, the number of measurements for each measurement item of not less than 3 times the mean value.
4 Measurement items and methods
4.1 Determination of material into the tank
4.1.1 into the tank of petroleum coke (or smokeless block) measurement used in the production of the metering device (belt scales or electronic scales cumulative measurement), or Artificial volumetric method of measurement, measure the accumulated amount in the measurement cycle.
4.1.2 The physical and chemical analysis of petroleum coke, petroleum coke was measured when the tank temperature, moisture content, applications based low (bits) heat and specific heat.
4.2 Determination of the fuel gas
4.2.1 Gas measuring gas flow meter, measure the gas within the measurement period cumulative dosage.
4.2.2 When the gas tank pressure and temperature, chemical composition and application based low (bits) Determination of calorific value. Gas applications based low (bits) heat can use the following formula (1).
Qymgdw = 126CO 108H2 359CH4 636C2H6 234H2S (1) where.
CO, H2, CH4, C2H6, H2S --- dry chemical composition of the gas volume fraction (%).
Specific heat is available and add look-up table method calculable.
4.3 Determination of calcined coke
4.3.1 Determination of calcined coke, field measurement using cumulative computational tools and instruments.
4.3.2 Determination of calcined coke application based low (bits) heat and specific heat.
