Description :

　　pressure gauge

　　A pressure gauge is an instrument that measures the magnitude of pressure and can be used to measure the actual pressure value inside a boiler. The change in the pressure gauge pointer can reflect changes in combustion and load. The stoker adjusts the combustion according to the indicator values on the pressure gauge to adapt to changes in external loads, and controls the boiler pressure within the allowable range to achieve safe operation. Therefore, pressure gauges are also indispensable safety accessories on boilers, and boiler operators often compare pressure gauges to "eyes".

　　water level gauge

　　1. The function and principle of water level gauge

　　A water level gauge is a measuring instrument that reflects the liquid level and is used to indicate the height of the water level in the boiler. It can assist the boiler operator in monitoring the dynamics of the boiler water level, in order to control the boiler water level within the normal range. Therefore, the water level gauge is also one of the main safety accessories of steam boilers.

　　The working principle of a water level gauge is the same as that of a connector. Because the boiler drum is a large container and the water level gauge is a small container, when they are connected, the water levels of the two must be at the same height. Therefore, the water level displayed on the water level gauge is the actual water level inside the drum.

　　Sewage discharge device

　　1. The role of pollution discharge;

　　During the operation of the boiler, the salt content in the water increases continuously due to the continuous evaporation and concentration of the boiler water. The so-called discharge refers to the continuous or regular discharge of a portion of high concentration salt containing boiler water and impurities such as sludge and scale from the bottom of the boiler, in order to maintain the quality of the boiler water.

　　The regular sewage discharge device is installed at the drum and collection box, mainly to discharge the sludge and scale at the bottom of the boiler. It generally consists of two series connected sewage valves and sewage pipes.

　　Temperature measuring instrument

　　Temperature is one of the important state parameters of a thermal system. In the boiler and boiler room thermal system, the normal thermal state of media such as feedwater, steam, and flue gas, as well as the good operation of equipment bearings such as fans and pumps, all rely on temperature monitoring.

　　Water level alarm

　　1. The function and principle of water level alarm

　　In order to maintain the normal water level of the boiler and prevent water shortage and full water accidents, boilers with evaporation capacity greater than or equal to 2 tons/hour must be equipped with high and low water level alarms in addition to water level gauges. Its function is to; When the water level in the boiler is higher or lower than the safe water level, the water level alarm will automatically emit an alarm sound and a light signal, reminding the boiler operator to take measures quickly to prevent accidents from happening.

　　The water level alarm is made by using the simultaneous rise and fall of the water level in the drum and the alarm to cause the floating ball of the alarm to rise and fall accordingly, or by utilizing the principle that the water in the drum can conduct electricity. The commonly used is an electrode type water level alarm.

　　Overtemperature alarm

　　The over temperature alarm is composed of temperature measuring instruments that can emit electrical signals, electrical control circuits, and sound and light alarm signals. When the temperature of the hot water boiler exceeds the specified limit or vaporizes, an alarm can be issued to enable the boiler operator to take measures to eliminate vaporization and overheating of the boiler water, in order to avoid damage to the normal circulation of hot water and the occurrence of overpressure.

　　Overpressure alarm

　　The overpressure alarm device is composed of pressure measuring instruments that can emit electrical signals, necessary electrical control circuits, as well as audio, lighting, alarm signals, etc. When the boiler experiences overpressure, an alarm can be triggered and combustion can be controlled through interlocking devices.
