The waste heat source of the 2,000t/d clinker production line is from the cooler and the pre-heater.

 

Average cooler waste gas parameter: 92360Nm³/h-240 Celsius Degree

Pre-heater waste gas parameter: 137000m³/h-335 Celsius Degree

The waste gas of the cooler should be exhausted from the middle stage. After modification, the waste gas parameter at the middle stage will be 53,400Nm³/h-340 Celsius Degree.

 

1) AQC boiler

AQC boiler produces 4.3t/h-1.0MPa-310 Celsius Degree superheated steam.

2) PH boiler

PH boiler will produce 11.9t/h-1.0MPa-310 Celsius Degree superheated steam

3) Turbine

Steam turbine with the main steam parameter of 1.0MPa-300 Celsius Degree. The total input steam amounts for turbine is 16.2t/h, power generation reach 2,890kW.

Water jet air ejector is selected as vacuum system of turbine;

DEH adjustment system is selected to make the parameter of steam stable.

 

To sum up, the thermodynamic system and installed solution are determined as follows:

Condensing water of the turbine is pumped to AQC boiler as supply of the hot water stage, outgoing water of the stage is used as feed water of AQC steam stage I and PH boiler. Superheated steam produced in AQC steam stage I and PH boiler merges together and is introduced to a turbine for power generation. Exhaust steam of turbine after work condenses to water, and is pumped to the AQC boiler, thus a complete thermodynamic circulation system forms.

Circulating water system including water circulating pump, cooling tower, a circulating water pond and pipe network will be adopted for equipment cooling. When the system in operation, cooling water will be pumped from water pond to production equipments in each department, the water after equipment cooling will be delivered to the structures by remained pressure of the circulating pump, and then the water is returned to water pond for circulation. By-pass filter are placed in order to ensure fine and stable operation of the system.

Two fiber glass cooling towers with capacity of 800m3/h per unit will be selected for water cooling.

 

Most of the additional water consumption is supplement water for cooling water system, the annual water consumption will be 184,300m³/a, and daily average water consumption will be 540m³/d, thus the capacity of water source should be 594m³/d.
