papermaking gas vacuum water tube boiler

Vacuum hot water boiler fuel gas vaporized to produce vaporized overtemperature problems reasons vacuum hot water boiler fuel gas, there are two major surfaces, one is vaporized over temperature, there is a is a partial vaporization, the causes leading to also have different, corresponding solutions are different. If the fuel gas vacuum hot water boiler heating system and hot water circulation loop gravity, it must be open gravity circulation valve. Because once the system failure caused by constant pressure boiler pressure device or system to reduce leakage, the position will not be caused by pressure vaporization system. After this case should an emergency shutdown immediately, and quickly identify the reasons, causing the system pressure to be reduced to exclude faults, the need to make the system running for some time in the cold state, until constant pressure returned to normal in order to determine the role of put into operation again. The local boiler vaporization problems are likely because of poor internal fuel gas vacuum hot water boiler water circulation conditions, the presence of water stagnation zone, tube angle is too small, the water velocity is too low and so on; there may be a forced circulation boiler (back the introduction of improper water distribution pipe layout, flow maldistribution caused when the fuel gas vacuum hot water boiler occur more serious pot of water vapor, combustion equipment should be stopped, but the circulating pump should continue to run at the same time open the occurrence of vaporization backwater valve circuit, to increase the flow of water. when the water hammer tube disappears before gradually returning operation of the combustion equipment.

Our business-to-steam boiler produces steam attaches great importance to the quality of good or bad, it will indirectly determine the quality of our food is produced dates. The fact that we choose fast boiler is correct. We are very grateful to our fast boiler manufacturing plant in a short time, installation and commissioning of these two steam boilers, advance our production line went into operation. --customer feedback

What are the advantages of a hot water boiler? its advantage is that there will never be any danger of explosion, but there can be no monitoring and inspection, and there is no need to consider the problem of pressure relief in the boiler room, to save steel and simplify the process, to reuse the waste boiler, to cancel the supplementary pump, and to protect the power outage well. Durable, saving users all kinds of investment. The operation of the hot water boiler is very simple, seal the fire, dust removal, add water, ignition this gives a step, when sealing the fire is to clear the ash first, remove the dust clean, then fill the coal hopper to close the coal door. The economic and environmental protection of vacuum hot water boiler is in line with the needs of social development. Therefore, vacuum hot water boiler is also popular with people, and its usage is not right or wrong. Often large, vacuum hot water boiler itself advantages determine its development space is huge. The instrument of the vacuum hot water boiler can automatically display the temperature and pressure, and the vacuum hot water boiler can be added coal twice in 24 hours, so that the vacuum hot water boiler can maintain constant temperature all day long. This will be more convenient to use. Hot water boiler system, each hot water boiler according to their main regulator proportional to the size of the change in the load. The fuel regulation subsystem of hot water boiler adopts a feed-forward-feedback cascade control system similar to the steam turbine power-frequency electro-hydraulic control system. Primary regulator adoption Proportional regulator, corresponding to frequency difference amplifier in steam turbine power-frequency electro-hydraulic regulating system, whose proportional band is equivalent to the unequal rate of steam turbine, whose size represents the capacity of hot water boiler with load, the larger the proportional band. The capacity of hot water boiler with load is stronger; The introduction of fuel feedback signal corresponds to the introduction of steam turbine first-stage pressure signal in steam turbine power-frequency electro-hydraulic regulating system, and its function is to quickly eliminate the spontaneous disturbance of fuel quantity of hot water boiler. Hot water boiler power consumption problem, we use the temperature to control the start and stop of the pump, in the low temperature as far as possible not to let the pump work, when the set temperature after the start of the water Pump. It is suggested that the boiler water should be treated by magnetization or softening in order not only to save energy, but also to prolong the service life of the boiler.

The steam produced in the steam boilers in paper mill is used to cook wood chips (along with the cooking chemicals). Steam is sent to dryer cans or Yankee dryer to remove the water from the sheet that the drainage, vacuum, and mechanical pressing sections of the paper machine can’t accomplish. The steam boiler also is applied to drying the paper product.
