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.
What are the advantages of aspects of the vacuum boiler vacuum boiler furnace because the inside is a vacuum thermal evaporation condensation heat exchanger country, thus adding heat medium during use, while saving environmentally friendly than other types of boilers. 1, due to the vacuum energy efficient vacuum suction hot water boiler technology in the production design, the boiler can operate in a vacuum state, the low boiling point, the latent heat of vaporization can be performed (latent heat of condensation), ternary wet-back design. E body having good heat transfer properties, and can effectively improve the radiation pairs. More efficient heat transfer area, energy. 2, a machine not only due to the vacuum boiler can be freely selected vertical, horizontal, fuel, gas and other models, and because of its heat exchanger and the header is an independent state, hot water and hot water load in accordance with any The actual handover is necessary. Users can fully meet the different requirements of hot water and sanitary hot water, hot water cleaning to ensure stability, to achieve multi-purpose. 3, easy to install due to the vacuum during boiler manufacturing modular design, using high-performance heat transfer element, the entire unit of small volume, not only easy to transport and storage, and easy to install. And also can be easily installed or in parallel using the plurality of units actually needed in the case of a small space.
Recently, the Weifang Municipal Quality Supervision Bureau investigation work for power plant boilers, boiler pipes mainly the situation, avoid boiler due to pipeline damage caused by explosion or other accident, serious economic losses and social impacts.
Quality Supervision Bureau adhere to problem-oriented, carefully study and strictly enforce the AQSIQ and the Provincial Quality Supervision Bureau of the requirements for the range of power plant boiler pipeline design, manufacture, installation, inspection, management and regular inspection of the use of accurate knowledge boiler safety awareness the importance of strengthening the red line awareness, risk awareness and responsibility to play, continue to maintain high pressure, strengthen safety supervision work of the power plant boiler tubes.
Bureau of Quality Supervision focus on checking whether the boiler tubes carry out regular inspections in the construction of power plant boiler accessories combination whether to implement supervisory inspection of manufacturing, installation work unit level meets standard requirements, flow meter housing if there is a security risk, whether the use of units developed power plant boiler tubes emergency plans and emergency rescue exercises, in a timely manner to improve the problems found.
To date, Weifang City inspectors were deployed 257 times, check the power station boiler unit 58, checking in with a number of boiler 193 units, eliminate safety hazards 78.
Boilers produce high-pressure steam, which is passed through a turbine to generate electrical energy (cogeneration). The exhaust steam from the turbine is passed through the multiple effect evaporator station and used to heat vacuum pans in the crystallization stage as well as for other heating purposes in the sugar mill.
