If the impurities in the boiler feedwater are not dealt with properly, carryover of boiler water into the steam system can occur. This may lead to problems elsewhere in the steam system, such as:
The quality of boiler feedwater is an important determinant of safe boiler operations and it should be monitored to maintain the quality within safe working limits. Boiler feedwater is treated to protect the boiler from two basic problems: the buildup of solid deposits on the interior or water side of the tubes, and corrosion.
If the hot oil pump of the fully automatic thermal oil heater is suddenly damaged and stops working during the operation, the boiler circulation will be blocked. If the fuel is still burning to make the oil temperature keep rising, it will cause the coking of the hot medium oil which is easy to cause a fire. If the fully automatic thermal oil heater catches fire due to the power cut during the operation, the boiler operator should quickly put out the fire in the furnace to stop the fuel from burning, and blow a large amount of cold air into the furnace to lower the temperature.
The vertical type and horizontal type are the two main types of boiler. The vertical gas-fired boiler has small volume and is suitable for small workshops or small production enterprises. It is often used in the fields of hot water and heating. The horizontal gas-fired boiler has larger volume with a wider application range than the vertical gas-fired boiler.
The high heat transfer of the boiler requires good medium. With the improvement of boiler in the production technology and intelligenlization, gas-fired boilers have more strict requirements for boiler operation medium in order to improve the boiler operating performance, reduce boiler failures and costs.
The food processing needs the steam or hot water to assist the production and improve the efficiency. Usually, the food plant needs the small tonnage boiler, so the coal-fired boiler is not recommended.
Coal-fired boilers are applied in various industries for the industrial and civil uses to generate steam and hot water. The steam is mainly used for production and the hot water is mainly used for heating and daily use.
The gas-fired hot water boiler heats up quickly and has the high thermal efficiency. It is widely used in the heating industry and production. What are the maintenance methods of the gas-fired hot water boiler?
