Reply to 1# Fu Huifeng – Production Management Log: Time: 0:00–24:00; Date: **** year ** month ** day. Product outputs: Ammonium alcohol, Synthetic ammonia, Urea, Briquetted coal/coal balls; Electricity generated: 10,000 kWh； Ammonia consumption per ton of product produced: Coal consumption: Electricity consumption: ; Steam consumption: ; Urea consumption per ton: Ammonia consumption: Electricity consumption: ; Steam consumption: Proportion of briquetted coal used in combustion: Production operation status **Day shift: For synthetic ammonia production, 10.6 compressors are in operation; 6 L94 fans and 1 L84 fan are used for desulfurization. 25 gas generation furnaces are in operation, with 23 furnaces supplying gas – there are periods when some furnaces are shut down ； Desulfurization pressure difference: Series 1 – 11–17 mmHg, Series 2 – 5 mmHg, Series 3 – 26 mmHg. In the semi-water gas, CO2 concentration is 9.4–9.3%, and CH4 concentration is 2.0%. Distillation was started upon taking over shift duties; Fan No. 4 was used to generate gas in Series 1. Fan No. 6 was shut down at 10:30, and around 10:50, Fan No. 3 of the desulfurization system in Series 1 was stopped depending on the situation. Urea: The load on the three units associated with urea production is 0.29 Mpa; the ammonia content in the ammonia solution is 7.6%, while the ammonia content in the exhaust gas released from the tail suction tower is 8.8%. Operation with large particles is normal ； The load on the two urea production units is 0.18 Mpa; the ammonia content is 11.7%, 13.4%, and 10.2% respectively. The gas lift efficiency is 77.1%, while the ammonia content in the off-gases from the fourth unit is 8.6%. Thermoelectric: Boilers No. 3, 4, and 2 in the thermoelectric section are in operation, with a load of 115 T/h. Briquette: 1 powder cage machine, 6 rod machines. Factors affecting this batch: Stable operating conditions in the first and second stages of urine production affect yield ； 9# The discharge of ash from the southern ash silo has an impact on carbon consumption due to backcarbonization. **Night shift: Synthetic ammonia production: 10.6 compressors are in operation; 6 L94 fans are used for desulfurization. 25 furnaces are operational for gas production, and 23 gas supply units are in use, with some of them temporarily shut down ； Desulfurization pressure difference: 11 mmHg for System 1, 5 mmHg for System 2, and 26 mmHg for System 3. In semi-water gas, the CO2 concentration is 9.2–9.3%, while the CH4 concentration is 2.0%. For urea production, the load on the three machines is 0.29 Mpa; the ammonia content in ammonia water is 7.7%, and the ammonia content in the exhaust gas released from the tail suction tower is 8.8%. Operation with large particles is normal ； The dual-machine load for urea production is 0.18 Mpa; the ammonia content is 10.1%, the gas lift efficiency is 77.2%, and the ammonia content in the off-gases from the fourth stage is 8.5%. Thermoelectric: Boilers No. 3, 4, and 2 in the thermoelectric section are in operation, with a load of 106 T/h. Briquette: 1 powder cage machine, 6 rod machines. Factors affecting this batch: Stable operating conditions in the first and second stages of urine processing affect production volume. Either, the short coal feeding time in each furnace for gas production affects consumption. 　 Handling of issues that occurred at night. 　 Factors affecting this class: 1、
