Coking and dust accumulation on heating surface. Whether it is slagging and ash deposition on the water wall of the furnace or ash deposition on the superheater, convection tube bundle, economizer and preheater, the measured thermal resistance of flue gas will increase, and the deterioration of heat transfer will worsen the cooling effect of flue gas, resulting in an increase in the temperature of boiler waste gas.
The horizontal hot water boiler burner refers to the burner used in the horizontal hot water boiler, which is the most important equipment in the auxiliary equipment of the horizontal hot water boiler.
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;
Boiler feedwater treatment system includes two parts: pre-desalination system and ion exchange desalination system.
The pre-desalination system includes ultrafiltration system, reverse osmosis system, dosing system, chemical cleaning system, compressed air system, etc.
The ion exchange desalination system includes ion exchange system, acid-base regeneration system, compressed air system, wastewater neutralization treatment system, etc.
The boiler feedwater treatment methods ar...
The boiler water film dust remover uses dust-containing gas to impact the inner wall of the dust remover or other special components, and forms a water film in some way, so that the dust in the flue gas is captured by the water film, thus purifying the gas.
Because a certain amount of air is usually dissolved in water, with the increase of temperature, the solubility of air decreases, and the gas is gradually separates from the water in the process of water circulation, and gradually gathers together to form large bubbles and even gas columns. Gas is often produced due to the water supplement, so the boiler exhaust valve must be used to avoid damage to the system.
The rated output of boiler refers to the maximum sustained output of industrial boiler under rated parameters (pressure and temperature) and certain efficiency. For steam boilers, the rated output is also called rated capacity, and the unit is t/h (tons/hour); For a hot water boiler, the rated output of the boiler is also called the rated thermal output, and its unit is MW.
