all thing waork in boiler
The choice between the all thing waork in boiler issue to be considered and the selection of different types: for selection of the boiler, some specific issues associated with the control requirements of this site to learn important product, then, is the need to carry out, and also to a firm grasp, so, in order to achieve a comprehensive and detailed, no omissions. So then, without further ado, to proceed immediately, so you can save study time, thus, to improve learning efficiency. 1. The company, which is in the selection of the boiler, the need to take into account what issues? In the selection of the boiler, for enterprises, it should be considered a problem, which is mainly have the following, are as follows: (1) In the production process heating or heating, for their own, how much hot water heating needs amount, or how much steam. (2) whether or hot water boiler steam boiler in the boiler parameters, and how is should achieve what extent.
The working principle and the internal structure of the steam all thing waork in boiler: steam boiler structural characteristics: 1, the steam boiler body welding: the main welding using advanced submerged arc welding process, welding quality assurance. All welds were 100% primary radiation detection according to the "Steam Steam Boiler Safety Technology Supervision", according to the eligibility criteria Ⅱ pole. 2, a horizontal steam boiler combustion three return all wet back structure. 3, before steam boiler, after the smoke box sealed with high temperature are graphite asbestos material, a reliable seal, to ensure that the steam boiler flue gas does not leak when run under a slight positive pressure conditions. 4, pipe thread: the second backhaul convection heating surface of the steam boiler, we used a threaded pipe, enabling the efficient heat transfer. Enhanced heat transfer, thermal efficiency of the steam boiler, a threaded tubular light pipe is equal to 2.4. Fluid flow within the tube wall near the fluid flow velocity is very low, the presence of fluid at the wall boundary layer is called, when the thermal resistance in series of several heat transfer water into the flue gas in the outer tube, the boundary layer the maximum thermal resistance, but the boundary layer is thin, as long as the boundary layer of little disturbance, as in an ordinary pressure in a pipe wall to the boss, the disturbance of the boundary layer, will greatly reduce the thermal resistance, is effective threaded pipe one way. 5, to make the system more energy efficient, continuous adjustment using the water supply, to avoid frequent pump start. During the period, the three-pass water smoke tube leaving a wide space, the pot to ensure natural circulation of water flow. 6, the body safety devices: at the rear of the steering steam boiler chamber is provided built-proof door, the steam boiler ignition and running, if the furnace gas deflagration occurs: timely relief, preventing the furnace deflagration, safe and reliable; as built after take-off will not hurt.
Factors affecting combustion in the all thing waork in boiler combustion rate reflects the number of units of time to burn combustible materials. Because the speed of combustion is the complex physical and chemical processes, combustion speed, depending on the speed of the combustible mixture into contact with oxygen and the rate of chemical reaction of oxygen and combustibles. Former said chemical reaction rate, also known as the chemical conditions; the latter, said physical mixing speed, also known as physical conditions. Chemical reaction speed and pressure of the reaction space, the temperature of the reaction mass concentration, and proportional. The actual combustion boiler, the main factors affecting the chemical reaction is the furnace temperature, the furnace temperature high, rapid chemical reaction rate. In addition to burning velocity associated with the chemical reaction rate, but also on the speed of the air flow delivery of oxygen to the surface of carbon particles, i.e. a physical mixing speed. Physically mixing speed depends on the relative velocity of the air and fuel flow disturbances, the diffusion speed. Chemical reaction rate, the mixing speed is physically interconnected on both a limiting factor for the burning rate. For example, under high temperature conditions should be a higher rate of chemical reaction, but if the low-speed physical mixing, decreased oxygen concentration, combustibles not have adequate supply of oxygen, the combustion speed results must fall. Therefore, only in the case of chemical conditions and physical conditions are more compatible in order to obtain a faster burning speed.
Blue Sky Battle horn started, our country constantly walking on the green road. Reduce atmospheric emissions of nitrogen oxides, improve air quality, but also the people a blue sky, the industry has invested in the construction of environmental protection go, Guizhou Baiyun Quan Lake Hotel is no exception. As we all know, fast all thing waork in boiler R & D in the field of clean fuel boiler never stopped, through market research and screening, Guizhou Baiyun Quan Lake Hotel in October 2017 signed a low-nitrogen Thalia T5 series vacuum hot water and fast boiler boiler for hot water supply and heating the hotel.
