how to solve cfb boiler flameout

The fuel regulation subsystem of hot water how to solve cfb boiler flameout adopts a feed-forward-feedback cascade control system similar to the steam turbine power-frequency electro-hydraulic control system. The main regulator adopts the proportional regulator, which corresponds to the frequency difference amplifier in the steam turbine power-frequency electro-hydraulic regulating system. The proportional band is equivalent to the unequal rate of the steam turbine. The size of the proportional band represents the capacity of the hot water boiler with load, and the larger the proportional band, the greater the load capacity of the hot water boiler. The capacity of hot water boiler with load is stronger; The auxiliary regulator adopts the proportional integral regulator, which corresponds to the power regulator in the power-frequency electro-hydraulic regulation system of steam turbine, and introduces the feedback signal of fuel quantity to the power-frequency electro-hydraulic regulation system of steam turbine. The effect of the first stage pressure signal of steam turbine is to eliminate the spontaneous disturbance of the fuel quantity of hot water boiler quickly. Hot water boilers are mainly used for heating and bathing. The hot water boiler circulates the hot water of the heat preservation tank through the hot water circulation pump and heats the hot water of the water tank again and again so as to achieve the purpose of bathing. The hot water boiler circulates the hot water of the heating pipe through the hot water circulation pump, and meets the requirement of people's heating through the radiator (radiator), and the hot water boiler and the hot water circulation pump cooperate with the heat exchanger can realize the double function of bathing and heating. The inlet speed of hot water boiler before start-up should not be too fast, usually no less than 4 in winter H, 2 to 3 hours in other seasons, especially at the beginning of the inflow. The inlet water temperature of a hot water boiler is generally at 50 ℃ 90 ℃, so that the difference between the feed water temperature entering the drum and the wall temperature of the drum is less than 40 ℃. The inlet water temperature of the gas-fired hot water boiler without complete cooling can be compared with the drum wall temperature, otherwise, the inlet water speed should be slowed down. When the feed water enters the drum, it always contacts the lower half wall of the drum first. If the difference between the feed water temperature and the drum wall temperature is too large, the speed of entering the water is fast, the upper and lower walls of the drum, the inner and outer walls will produce a larger expansion difference, resulting in a greater additional stress to the drum. Causes the steam drum to deform, produces the crack when serious. Because the wall of the drum Thick, slow expansion, and connected to the drum wall thin wall, expansion faster. If the inlet temperature of gas-fired hot water boiler is too high or the inlet speed is too fast, it will cause uneven expansion, crack of welding joint and damage of gas-fired hot water boiler.

Dezhou City, Shandong Province, located in northern China, the winter heating livelihood security is the top priority. According to statistics, the main city such as the German city of existing heating how to solve cfb boiler flameout 63 units, for the protection of the safe operation of the winter heating boiler, the past few days, the German city Bureau of Quality Supervision special equipment inspectors to carry out a comprehensive examination of special law enforcement actions against these heating boilers.

Check the main content around the registration and inspection of boilers, operator's safety if the holder case posts, etc to focus your heating boiler operating conditions, in particular the various safety accessories and safety devices especially by the attention of inspectors. By the inspection activities, it may be within the control range as much as possible, to ensure the safe use of heating boilers.

ZG provided two WNS series steam how to solve cfb boiler flameouts for its production base. This type of WNS horizontal steam boiler adopts a large-area combustion chamber design to make combustion more fully, and adopts an advanced wave furnace structure, which increases the heat transfer area while satisfying the free expansion of the furnace after it is heated. The burner with good self-control performance is configured to achieve maximum automation. Fully in line with the needs of future production in the local textile mill for the production of steam supply.also the horizontal boiler has such as easy operation, high output, clean compusation and so on.

Before using steam how to solve cfb boiler flameouts, but also note the use of taboos, can not be arbitrary use, to prevent unforeseen circumstances, staff should make the appropriate training. He too is a modern industrial equipment, bring a lot of convenience to people's life and work, but there will be inadequate.
