Food plant causes corrosion and the effects after stopping the boiler factors: food factory after disabling boiler corrosion causes and influencing factors after food factory boiler shutdown, with decreasing pressure and temperature inside the boiler steam condenses into water, boiler a vacuum inside, the outside air leaks into the furnace, the oxygen and water vapor in the vapor state. Metal is prone to corrosion. Boiler structure, if you do not take some measures to stop the use of corrosion is inevitable. For example, can not be discharged superheater superheater water. When the internal heating surface has a water-soluble metal salt scale, when it absorbs water, will form a high concentration solution of salt, which will aggravate the etching stopper, internal corrosion is formed ulceration. Often this is the entrance to the superheater. Because the separated saturated steam upon entering the superheater boiler always carry a small amount of water, the saturated vapor absorption heat upon entering the superheater, the boiler water is evaporated into steam, boiler water salt deposited on the inner wall of the superheater. Heater inlet pipe.

The advantages of vacuum gas boiler descriptions vacuum gas boiler itself also have more features, vacuum gas boiler matched customers were more interested in updating operations during manufacture. It can be useful for consumers to supply convenience. Well, to start that is that explanation from the people to see the vacuum gas boiler advantage. First, a high level of automation high level of automation vacuum gas boiler itself, based on the consumer's command to complete self-purging and electronic ignition and other operations, in particular, the operation is also reliable and stable, but also the occupation fire-fighting equipment troubleshooting, reduce the hidden dangers caused. Second, the occupation of the provincial natural gas flame spoiler, can improve the heat exchange, greatly reduce heat loss, as consumers save more natural gas, but also consumers, especially in the days of easy operation and does not require the use of with someone on duty, it will save time and save energy. To sum up some of the characteristics of vacuum gas boiler details, after several passes above said, there is no such public facilities and also have more understanding. When, after the selection of heating facilities, intend it can be more.

Problems existing boiler which a vacuum tube bundle effect bunching effect is widely present in the heat exchanger shell, likewise, vacuum boiler is inevitable. Nusselt proposed an improved condensing heat transfer coefficient formula for 1916. However, due to many differences in bundle properties (heat medium) temperature is saturated, the surface tension outside the refrigerant, the corrected correlation will also be corrected based on experimental results. But again, the bundle effect is still inevitable. 2, it is difficult to maintain the degree of vacuum maintenance and control of the effect of vacuum, vacuum boiler born. When the vacuum boiler stability, the interior portion of the vapor in the vapor space for heat exchange bundle and condensed into a liquid, negative pressure environment part for maintaining a vacuum in the boiler. Theory, boiling and absorbing heat cold water evaporation eventually will be in equilibrium, with the actual amount of heat during operation, the vacuum pump to maintain the boiler typically require external pressure balance, control the heat required to maintain combustion stability of adjusting the water temperature. These external adjustable mechanical means to destroy the balance of the system itself, not only the vacuum boiler system more stable and unstable heat transfer process last longer. 3, exhaust loss if these two exist only in the vacuum boiler, improve energy efficiency research boiler eternal subject. Currently, most vacuum boilers are gas-fired boiler for the boiler, the exhaust gas loss of vacuum insulated with appropriate measures to become a major energy loss.

President of the association leaders to introduce this year is an important period of the 20th anniversary of the group. After 20 years of development, the Group to "create convenient boiler boutique users" for the mission, adhere to scientific and technological innovation, all-round, multi-channel strengthen technological innovation, we have launched a variety of users for the use of energy-saving, low new nitrogen, gas boiler to become the industry leader. Luhai Gang Jiao Ling Wang, president, accompanied by the Secretary-General and his party visited the Group's newly completed R & D base, clean fuel test center, exhibition hall and a multimedia remote monitoring center.
