1. What table is used to monitor and control the boiler water separator? The boiler water separator is mainly monitored and controlled by three instruments: pressure gauge, thermometer, and flow meter. 1. The pressure gauge is used to monitor the system pressure inside the water separator in real time, ensuring that it operates within a safe range (usually the working pressure of the heating system used in Kaizhou is 1-2 bar). Abnormal increase or decrease in pressure indicates the possibility of system failure. 2. Temperature gauges are usually pointer or digital, directly installed on the main supply and return water pipelines of the water separator, to display the real-time supply and return water temperatures of the system, which is an important basis for adjusting the combustion insulation of the boiler. 3. Flow meters (such as mechanical flow meters or ultrasonic flow meters) will be installed in each branch of high-end or large systems to accurately measure and display the actual water flow rate of each loop, in order to carry out hydraulic balance debugging and ensure uniform heating supply. 2. Boiler steam flowmeter, consult experts to determine the problem
Water evaporates into steam, and its expansion ratio is 1860 times under normal pressure.
. Under different pressures, its density also changes accordingly. Below are the answers to your questions one by one:1. The steam flowmeter consists of two broad trace parts. The first part is the sensor part, which is commonly known as the flowmeter. The equipment installed on the pipeline includes vortex street, orifice plate, Annubar, pulse and other forms. The second part is the integrated computing device, which includes functions such
2、 The second question has already been clarified in the above answer. The density and enthalpy of water vapor at different pressures are different. You can find it on the soda characteristics table.
3、 Regarding the third question, theoretically speaking, there must be some changes, but in practical operation, the enthalpy value of the dry saturated steam tank under a pressure difference is relatively small, and the desired fuel consumption does not change significantly. According to the law of conservation of energy, the energy output will change, but not significantly, so it is generally ignored in production assessment. In addition, if it is superheated steam, the enthalpy value needs to be calculated. If you have any further questions, you can leave a message.
3. Installation precautions for boiler steam flow meter
When measuring liquid, it is necessary to ensure that the flow meter sensor is always completely filled with the medium and free of entrained gas.
. Provide sufficient straight pipe sections upstream and downstream of the instrument and ensure a non curved symmetrical shape. Install valves downstream of the instrument as much as possible. Vertical installation is usually preferred, as the upward flowing fluid ensures that the instrument is always full and the solid components in the
