berjaya water boiler kuching
How to distinguish the correct pressure hot berjaya water boiler kuchings and pressure hot water boiler, furnace pressure to see changes in pressure hot water boilers and pressure boilers biggest difference lies in the pressure. Even the low-cost pressure hot water boiler, the furnace pressure hot water is always consistent with the atmospheric pressure does not change as the temperature changes; the contrary, because of the pressure boiler furnace and water system is closed containers and piping components will naturally follow with increasing water temperature changes. See changes in pressure in the furnace is a more intuitive way to distinguish between the two. Second, look at the professional level control problems because the supply pressure hot water boiler is not operating pressure, the pressure in order to achieve operation of the boiler circulating pump inlet and the outlet is connected to suction hot water in the heating boiler to a user, users return pipe and boiler water inlet necklace, equal to the amount of water into the water. Thus, pressure hot water boiler water level control problems still top box connected to an opening in the drum full of water, the water level control problems. The pressure hot water boiler water level control is no problem, which is one of two significant differences. Third, look at the structure of constraints pressure hot water boiler on the structural parameters of the issue, compared with pressure hot water boiler much simpler. Unlike the structure of the pressure in the boiler strictly limited boiler capacity, parameters, mounting position, etc., only reasonable pressure hot water boiler heating surface arrangement, water circulation to ensure reliable basis, little limitation on the structure, may be large degree design, construction and installation according to actual needs of users, more flexible and convenient. This is the pressure hot water boiler then more and more important reason for the user's favorite move. In summary, the difference between the atmospheric pressure hot water boiler and hot water boiler mainly in furnace pressure changes, whether the water level under control and whether there are structural limitations in three areas. In fact, the difference between the two is far more than that, they are there is a difference in terms of service life, water supply, safety performance, if you carefully study will certainly find many differences, after contrast, I believe it will not hesitate to choose pressure hot water boiler.
Recently, Zhongshan City, Guangdong Province, the ecological environment expanded Bureau held a working high-pollution fuel combustion zone ban will promote further urge the major companies on time and quality completion of boiler rectification task. It will be mentioned in the need to deeply Publicizing the newly revised "Air Pollution Prevention Regulations of Guangdong Province" and "boiler air pollutant emission standards" and to implement the next phase of work to expand the scope of the ban on burning zone, Zhongshan City.
District policy is to implement the ban on burning blue sky, Zhongshan City, to win the Battle of the most important, relevant departments, district towns, enterprises should pay full attention and positive action in order to "limit Forced, territorial responsibility, multi-pronged approach , coordinated implementation of the "principle, should work together to create synergy, take the following measures to ensure that all targets are met within the deadline.
According to published Zhongshan City, "about expanding the scope of high-pollution fuel combustion zone ban notice" requirement, in addition to coal-fired cogeneration thermal power plant units have been built high-pollution fuel industrial equipment must be removed or completed by June 30 this year clean energy transformation, all enterprises should actively cooperate with government departments to complete the rectification task on time and quality.
According to requirements "Boiler Air Pollutants Emission Standards" (DB44 / 765-2019), and from April 1 this year, the province's start step by step implementation of the new air pollutant emission standards boiler, new boiler effective from April 1 this year, in accordance with the different regions in which, since 1 July 2019 or 1 July 2020 to implement the new standard boilers. Compared with the original standards, new standards particulate matter, sulfur dioxide, nitrogen oxides and other pollutants received strict emission limits help to further reduce the total emissions of air pollutants.
Gas boiler pressure test process
Gas steam boiler with a certain high pressure, high temperature steam to the output of above 100 deg.] C, of a clearly defined pressure vessel. After completion of the boiler installation, as required, hydrostatic testing must be done to verify the tightness between the valve body and the boiler.
The reason for the high exhaust gas temperature following points 1, leakage is serious leakage refers to the furnace, flue, etc. due to poor quality welding or other causes leakage phenomenon is an important reason for the high temperature exhaust gas boiler. Mainly refers to the furnace roof seal leakage, see the crater, and the bottom seal Manhole leakage at the sink; chimney flue leakage refers to leakage when the ambient air in the negative pressure operating chamber wall and at the flue imprecise, especially in the furnace end leakage greatest impact. Leakage will make the exhaust volume increases, exhaust heat loss will also increase. 2, hot air factor is too large the air ratio has an important influence on the boiler thermal efficiency and combustion conditions. When the air ratio is too large, the amount of the boiler flue gas emissions will increase, so that the boiler flue gas heat loss increases, induced draft fan, blower power consumption will increase, resulting in reduction in thermal efficiency. Choose the right air ratio, it will reduce the energy losses, get a higher thermal efficiency of the boiler, and the safe operation of the boiler. When the load changes, can be adjusted into the furnace fuel and air quantity, the corresponding changes in the combustion conditions. 3, more fuel moisture content on water in fuel combustion is the main cause burning fire difficult, and reduce the temperature of the combustion zone, the fuel may not fully burn. When the fuel water every 5% increase, due to the thermal efficiency of the boiler heat losses will drop about 0.5%. 4, heating surface scaling, fouling, boiler slag when the heating surface due to poor water quality when the water content of the fuel or the like caused by excessive scaling or corrosive conditions, will produce heating surface scaling, fouling, slag and other undesirable phenomena, will effect of heating surface and heat transfer to the flue gas, the flue gas can not be cooled in a timely manner, resulting in exhaust gas temperature.
