Run time, and the thermal conductivity of the gas boiler gas boiler after its long run, inevitably its scale and corrosion problems in the use of the process, the main reason the gas boiler scale formation is due to the water with ingredients hardness, high temperature, high pressure continuously concentrated by evaporation. Gas boiler furnace in which it is running a series of chemical and physical reactions will occur during use will effectively form a dense and hard scale on the heating surface, which would lead directly to lower the heat exchange efficiency and due to corrosion under the scale factors, it will lead to reduced boiler water wall furnace heat absorption. The outlet temperature of the gas boiler furnace during the course of an increase, so that losses will increase in the boiler, it will be effective to reduce the heat transfer in the water wall fouling equipment, so it is very likely to cause the water-cooled wall tube wall temperature results in an increase of the thermal conductivity of scale squib gas boiler waterwall at runtime only a few tenths of a steel material, when its heating surface fouling, so that the heat transfer will be impeded, in use process in order to maintain a certain boiler output, it is necessary to raise the temperature of the fire side. During the washing process gas boiler which may be employed in an efficient and environmentally friendly non-corrosive cleaning agent for cleaning the boiler, so that the device will expose the metal tube primary colors, because the reduction of algae and biological sludge fouling effect. Note that after the need for effective gas boiler furnace during ignition of smoke was observed and the temperature of the main steam temperature, the case where the pressure rise of the main steam, which is encountered after the boiler ignition temperature of tobacco will significantly increase the speed of the smoke or temperature Pianman It does not rise to the herd to immediately check the oil gun fire conditions.
Natural gas heating steam boiler supplier by what configuration consisting of environmental policy and natural gas high pressure steam boiler their good performance advantages, let natural gas steam boiler stand out in a crowd boiler types, all ages, and use more and more users. Many users before purchase natural gas steam boiler, the boiler due to insufficient understanding, very easy to be deceived poor sales. Today we have to say something about, what are the natural gas steam boiler configuration consisting of it so that we have a general concept. Natural gas steam boiler is a series of devices can be roughly divided into two main parts and auxiliary equipment. First, the main member 1, the chamber: the fuel burn-up and ensures that the boiler outlet temperature of the flue gas is cooled to a value of convection heating surface capable of security. 2, the drum: the respective heating surface and joined together and the boiler water wall tubes and other components decreased water circulation circuit. Soda storage drum, can adapt to changes in load, with internal steam separator means to ensure the quality of soft drinks, no DC boiler drum. 3, water wall: mainly radiation heating surface of the boiler, the absorption of radiant heat furnace heated working fluid to protect the furnace wall and the like. 4, combustion equipment: the fuel and air required for combustion of the fuel into the furnace ignition and stable good combustion. 5, air preheater: heating the fuel with air, in order to enhance ignition and combustion; flue gas waste heat absorption, reducing the exhaust gas temperature, increase boiler efficiency. 6, the furnace walls: a housing to protect the boiler, since sealing and insulation. Heavy furnace wall of the small boiler may also function as a support member boiler. 7, the frame: a support member and fixing the boiler. Second, the auxiliary device 1, the wind equipment: induced draft fan and chimney via the flue gas generated in boiler operation sent to the atmosphere. 2, dust removal equipment: removing fly ash in the boiler flue gas. 3, the fuel supply apparatus: fuel storage and transportation work 4, water supply equipment: a water pump to feed water through the water treatment device into the boiler. 5, the air blowing apparatus: the air blower means through application exports the furnace air preheater and a coal grinding heat. 6, the automatic control device: automatic detection, process control, automatic protection and automatic adjustment. Natural gas steam boiler is mainly from these major components and auxiliary equipment components, making them a reasonable match to achieve efficient boilers, environmental effects, but also improve the thermal efficiency of the boiler, the boiler at work so that you can achieve safe and reliable results.
Recently, in Qinghai Province Jigzhi County Market Authority carried out a special inspection of boiler safety within the county, mainly in order to further strengthen the special equipment safety supervision, investigation and potential risks.
County Market Authority was held on June 8 special meeting to make arrangements for this special inspection work; the meeting, Secretary of this special inspections put forward specific requirements: Either the county government and relevant departments in accordance with the superior, all in the area to check boilers, boiler and disabled to look back, to verify the implementation of the rectification; the second is to designate a person to carry out checks to ensure that this special inspection into effect, produce results; the third is to check violations found to be severely dealt with according to law.
Subsequently, according to the spirit of the meeting, Jigzhi County Market Authority Board redoubling its efforts to carry out special inspections. 5 out of law enforcement officers were examined using 10 units. The county has been reported to stop the boiler After registering with and eleven inspection and verification. Focus on checking whether the boiler inspection, whether the registration, check whether safety accessories in place, whether fireman certificates and other issues, focusing on correct pressure boilers, waste heat and pressure tanks and other equipment as well as the use of pressure boiler overpressure operation and other illegal operations behavior, found hidden among all checks for disposal in accordance with law, to ensure the safe operation of the boiler county.
Next, the county will further increase the pressure in the boiler with supervision and do routine inspections and safety management, strengthen the use of units to pay a return visit found the problem of checks put in place to promote the use of the unit responsibility, and earnestly safeguard the life and property Safety.
Henan newly installed gas boiler 1 what kind of work before starting. Henan newly installed gas boiler before starting what should be done? These include: the tightness of (1) hydrostatic test (overpressure test), test pressure member. (2) Trial and various auxiliary electric door damper check. (3) oven. Water inside wall of the furnace and gas water boiler tubes Henan removed. (4) cooking stove and pickling. Remove grease deposits in the evaporator heating surface system, rust, oxide scale and corrosion products, and other like with lye and acid. (5) furnace aerodynamic field test. (6) flushing pipe. Henan boiler with gas flushing a self-generated steam, the second steam duct heteroaryl residue. (7) check security doors. 2. Henan gas boiler before start time and temperature of water on what regulations? why? Water speed before the start of Henan gas boiler should not be excessive, winter generally less than 4h, other seasons 2 ~ 3h, especially in the beginning of the water should be slow. Cold boiler water temperature is generally not more than 100 ℃, so that the temperature difference between the feedwater entering the drum drum wall temperature is not more than 40 ℃. Henan not completely cooled gas boiler drum water temperature, mutatis mutandis, wall temperatures, generally the difference should be controlled within 40 ℃, it should slow down or speed water. The reasons are: (1) Since the thick-walled drum, slow expansion, the wall of the tube is connected to the drum wall is thin, expanded rapidly. If the inlet water temperature is too high or too fast, uneven expansion will cause the weld cracks occur, resulting in damage to the equipment. (2) when the water supply enters the drum, the drum is always in contact with the first half wall, if the water temperature and the drum wall temperature difference is too large, the influent fast speed, on the drum, the lower wall, the inner and outer wall inter will have a greater expansion difference, caused a large drum to additional stress, causing deformation of the drum, when severe cracks.Free Chat
