Make-up water rate refers to the proportion of treated water added to the boilers, steam turbine equipment and its thermal systems and participating in the circulation of steam-water systems in the boiler steam volume in the calculation period.
Prepare relevant technical data, including technical data of boiler manufacture and installation, boiler use registration data, boiler operation records, water quality test records, repair and modification records, accident records and previous inspection reports;
With the rapid development of economy, the demand for industrial boilers in modern enterprises is increasing. Because of the particularity and complexity of industrial boilers, we must understand the problems clearly before purchasing. According to the question "what is the main function of boiler superheater", ZOZEN Boiler will answer the doubts first.
Boiler water circulation refers to the circulating flow of water and steam-water mixture on the evaporating heating surface of boiler. What is the working principle of the latest water circulation system of boiler?
MFT means the main fuel trip. To put it simply, when the protection signal is activated, the control system automatically cuts off the boiler fuel system and links the corresponding systems and equipment, so that the whole thermal system can be safely shut down, the boiler can be protected, and the fault can be prevented from further expanding.
The ignition system of gas-fired boiler adopts high-energy igniter, which belongs to low-voltage capacitive discharge device. Its main structure is composed of nddh high-energy igniter, nddz igniter and nddl shielded ignition cable.
Ash accumulation on the heating surface.
The scaling and ash deposition on the water-cooled wall of the furnace and the ash deposition of the superheater, convention tube bundles, economizer and preheater can increase the thermal resistance of the flue gas, weaken the heat transfer, lessen the cooling effect of the flue gas and increase the exhaust gas temperature of the gas-fired boiler.
Too high excess air coefficient.
Under normal circumstances, as the furnace outlet excess...
Power boilers take the chemical energy stored in fuel, convert it to heat energy in the combustion process, and transfer that heat energy to water to produce steam. The transfer of energy from combustion gases to the water and steam is called heat transfer.
