The boiler water level gauge is a detection instrument that shows the water level of the boiler, and it is one of the important safety accessories of the steam boiler.
Boiler efficiency refers to the percentage of boiler effective utilization heat to boiler input heat per unit time, that is, the percentage of effective utilization heat per standard cubic meter of gas fuel. ZOZEN gas-fired boilers all adopt large furnace design, with the efficiency as high as 98% and NOx emission as low as 30mg/Nm3.
Drum boiler refers to boiler equipment with boiler drum, which is an important pressure component in natural circulation boiler and the connecting hub of the three processes of boiler heating, vaporization and overheating, and plays a connecting role. Water becomes qualified superheated steam in the boiler, which goes through three processes: heating, vaporization and overheating. Heating from feed water to saturated water is a heating process; The vaporization of saturated water into saturated steam is a vaporization process; Heating saturated steam into superheated steam is an overheating process.
Boiler parameters are the main indicators of boiler performance, including boiler capacity, steam pressure, steam temperature, feed water temperature, etc. Boiler capacity can be expressed by rated evaporation or maximum continuous evaporation. Rated evaporation is the amount of steam continuously produced per unit time under the specified outlet pressure, temperature and efficiency. The maximum continuous evaporation is the maximum amount of steam that can be continuously produced per unit time under the specified outlet pressure and temperature.
At the same water temperature, the larger the excess amount of oxygen scavenger in water, the faster and more complete the chemical reaction. Under the same dosage, the higher the water temperature, the better the deoxidization effect. Under the same deoxidization effect, the higher the water temperature, the smaller the dosage.
Low pressure and high temperature: the thermal oil heater can obtain higher working temperature at lower operating pressure, and the maximum temperature of liquid phase can reach 400°C.
