slaughtering and processing natural gas hot water pipe boiler supplier

Work and family considerations slaughtering and processing hot water pipe boiler supplier shutdown boiler inspection carried out maintenance before restarting operation, the need for a series of maintenance work, combined with the user experience and learning references, be aware of the following specific boiler maintenance work and family considerations. 1. Preparation (1) before the boiler before the boiler equipment maintenance inspection, as in normal shutdown program is stopped, slow cooling, water circulation and ventilation through the furnace, and gradually lowering the temperature of the boiler furnace. When the temperature dropped below 80 ℃, the door opening open various checks on the boiler. Prevent steam, hot water or cigarette burns when opening the door opening. (2) Steam test boiler feed water, should be separated from the sewer line with the respective other operation of the boiler. Blind for a separator plate should be sufficiently strong to avoid high pressure medium in the broken drum is operated. This clearly indicated the blocking position. Combustion chamber and the flue (3) Check the boiler should be separated from other operation of the boiler. Flue and ventilation doors must be closed tight after separating. 2, preparation of the pressure vessel (1) before the container inspection prior to examination, to be completely cut off the connection tube between the container and the gas pressure or other equipment, particularly equipment using flammable or toxic media. Not only must the valve is closed, and must be sealed with blind plates, so that the valve leaks, resulting in leakage of flammable or toxic gases into the vessel, fire, explosion or poisoning. (2) all media in the container to be discharged. Containers containing flammable, toxic or suffocating medium should be cleaned, replaced or sterilized, by sampling and analysis. A power supply associated with the container, such as a container with a stirrer, reversing mechanism, etc., must be cut off, and a clear flag indicating not allowed to connect. 3, a boiler maintenance considerations are (1) Note ventilation and monitored prior to entering the drum, the container, the drum must be opened, all in the hole hand hole in the container and the collection tank, the air convection period and adequate ventilation. When entering the drum and the container inspection, one must monitor the external device. Before entering the combustion chamber or flue must also be ventilated. (2) Note that the detection of electrical safety in wet flue drum and when the lighting voltage should not exceed 24 volts, with electric lighting. In dry flue, using appropriate security measures, it may be no more than 36 volts lighting voltage. When entering the test vessel, should be used no more than a low-pressure proof lamp voltage 12V or 24V. When the supply voltage detection equipment and maintenance tools than 36V, good insulation must be reliable grounding cord. Boilers and containers should not be used flame. (3) removably connecting member pressing the forbidden band in the inspection of boilers and pressure vessels, pressure if the fastener member needs to unload or screwing, must fully release the pressure, before it can be. Bolts or other fasteners can not be tightened or unloaded at the boiler pressure, in order to prevent accidents. (4) prohibits self-test instead of the hydraulic pressure to the boiler pressure vessel test pressure test generally use water as the pressure medium, there is no gas as a pressure medium, otherwise it is very dangerous. For structural reasons the like, water can not be used as a pressure medium test individual containers, when instead of hydraulic pressure in accordance with design requirements, should be thoroughly checked before the test, check the strength and reliability of the measures taken. Prior to implementation should conscientiously implement the design in accordance with the provisions of, and prior consent of the security sector.

Select four reasons slaughtering and processing hot water pipe boiler supplier manufacturers to provide a great convenience to every aspect of people's daily lives, and save a lot of resources, with a high economic nature. At the same time the potential for sustainable development in the market is very large, there is a tendency of increasing demand. Select good quality has started to become the ultimate goal of buyers, then what good quality standards is it? The reason so many consumers choose what is it? The answers to these questions are summarized below. 1, with the gradual development of low-cost natural gas project in the country, making natural gas prices continue to decrease, so that the knock-on effect of fuel costs began to decrease. In addition, because of the high cost of high efficiency can be improved boiler combustion efficiency and save a lot of fuel. Boiler and extremely durable, maintenance costs are not high. So the cost of purchased fuel decreases, the fuel saving is also obtained, also decreases the cost of the final lot; 2, due to the use of high flue gas flow is disposed three return efficiency, wet-back configuration such that the whole heated butt welding large area. While the tail is arranged flue gas condensation recovery, the maximum degree of control may be the temperature of the exhaust, the heat efficiency of the boiler is very high. Using automatic and continuous burner electric control, so that a particularly high combustion efficiency; 3, safe and stable comprising a plurality of professionally designed overpressure protection over-temperature, and water leak detection, and other functions flameout. By these functions play very safe and reliable operation of such a boiler; 4, uses a space-saving quick structure, and the base of the whole boiler with strong steel. This design facilitates easy installation and transportation processes, as well as greatly reducing the space footprint, and save a lot of space. The above is about four advantages, but also the existence of these advantages it has become a choice of four reasons, including low cost, high efficiency, safe and stable and space saving these four aspects. Factory in the purchase of these four reasons may wish to determine the basis for the selection of suitable, high-quality products.

2. Oxygen corrosion

For the biomass fuel boiler pressure parts,the water side is mainly electro chemical corrosion,the fire side (or flue gas side) is mainly chemical corrosion.The oxygen corrosion belongs to electrochemical corrosion, it is mainly caused by the dissolved oxygen in water.At room temperature,the dissolved oxygen concentration is about 9.1mg / L,according to the GB1576-2001 “industrial boiler water quality” requirement ,the rated steam pressure should not be more than 1.0MPa,the dissolved oxygen concentration should not be more than 0.1mg / L,otherwise,it is likely to lead to metal corrosion.
