Borler Software: How to choose the pressure system type in water tube boiler calculations?

When selecting the medium-pressure system type, specific process and application requirements need to be taken into account; usually, the choice is made based on the actual circumstances. Generally, it can be considered from the following aspects: 1. Operating pressure: The type of medium-pressure system should be selected based on the operating pressure of the boiler. Generally, for boilers with an operating pressure ranging from 3.8 to 13.8 MPa, either a natural circulation or forced circulation system can be used. 2. Steam flow rate: If the steam flow rate is high, a natural circulation system can be selected ； If the steam flow rate is low, a forced circulation system or an indirect circulation system can be chosen. 3. Operation mode: The type of medium-pressure system is selected based on the boiler’s operation mode; for boilers with high energy-saving requirements, an indirect circulation system can be used. 4. Requirements for the boiler structure: Certain structural factors of the boiler need to be taken into account, such as the requirements for the boiler shell and the limitations on the space at the bottom of the boiler. The type of medium-pressure system to be chosen must be determined based on these specific conditions. .
