KTE - 7000SB

SOLAR WATER HEATING & BOILER EXPERIMENTAL EQUIPMENT




Equipment Introduction

  • The Solar Thermal Boiler Training System (KTE-7000SB) is designed to support understanding of solar heat collectors, heat storage, and heat control systems.

  • It enables comparative testing and practical experiments by calculating thermal energy under different load conditions using three types of loads.

  • The system allows performance testing of a solar thermal boiler using both artificial sunlight and natural sunlight, and provides education on the structure and operating principles of solar thermal boiler systems.

  • Users can conduct experiments by collecting natural sunlight after installing the solar heat collector outdoors, and gain hands-on experience in system control through integrated control systems.





Equipment characteristics

Operation Principles of Active Solar System

Heat Collecting Process

  1. Solar heat energy is received from the sun.

  2. The temperature inside the solar heat collector increases.

  3. Pump 1 and Pump 2 start operating.

  4. The heat collecting medium enters T2 (collector inlet), flows through T14, where it absorbs solar energy, and exits through T3 (collector outlet).

  5. The heated medium then enters the heat exchanger, where thermal energy is transferred to the heat storage medium through heat exchange.



Heat Storing Process

  1. Pump 1 (heat collecting circulation pump) operates in conjunction with Pump 2.

  2. The thermal medium stored in the heat storage tank flows from T5 (tank outlet), passes through the heat exchanger, and enters T4 (tank inlet).

  3. During this process, heat energy is transferred from the heat collecting medium to the storage medium and accumulated in the upper section of the heat storage tank.



Heat Processing (Heat Utilization Process)

  1. When the internal chamber temperature T13 is lower than the preset value,

  2. Pump 3 starts operating.

  3. The thermal medium stored in the heat storage tank passes through a distributor and flows into T8 (or T10).

  4. The medium transfers heat to the chamber through the heat exchanger, and then returns to the heat storage tank via T9 (or T11).
