Zhengzhou Sunrise Optoelectronics Technology Co., Ltd. by the Dongxu Group, Henan Province, the state-owned asset management companies and Zhengzhou Investment Holdings Limited jointly made, mainly engaged in flat panel display and solar industry design materials, manufacturing and sales operations. Sunrise Optoelectronics project has been put into a production line, the second phase will continue the expansion, three new production lines to meet the production needs of Project Phase II, Sunrise Optoelectronics urgent need to increase new boiler equipment. After investigation and screening of a number of boiler brands, determined to cooperate with the fast boiler, steam signed a 10-ton integrated condensing gas 2t fired steam boiler (WNS10-1.25-Y.Q).
Because of the particularity of the oil-gas boiler, from the initial construction preparation to the long-term acceptance of the project, there will be some problems to be paid attention to, and what should be complied with? Boilers need to follow the steps step by step to complete. What needs to be observed in the process? Oil and gas dual-use boiler installation before construction, first in accordance with the rules to first handle the boiler installation approval formalities, pending quality and technical supervision bureau approval after! Safety valve is an indispensable safety protection device in industrial boiler. Lever type safety valve can be often used, it can be divided into two types: single lever and double lever. Well, it was run in an industrial boiler. How does the lever-type safety valve work in the process? Why to carry out the air pressure test on the boiler? The lever type safety valve in industrial boiler is basically composed of valve core, seat and important lever, weight hammer and position limiting device. It acts on the valve core through the heavy torque of lever and weight hammer to flatten the pressure of steam. The main energy consumed in the operation of oil-fired boiler becomes fuel oil, so the quality of fuel oil will be directly related to the whole combustion state of the boiler, so how to choose fuel oil to supply to the oil-fired boiler? Generally divided into light fuel oil and heavy fuel oil two major categories. Fuel-fired boilers burn differentiated fuel oil The composition of the oil supply system will be different because of the different characteristics of the oil.
The working principle of 2t fired steam boilers and steam boilers for industrial structural features has brought great convenience, steam boilers led to the development of the times, the following small series to introduce you to the structural characteristics and working principle of steam boilers. Steam boiler is producing steam-based machines, people use a lot, but many of its structure and working principle are not fully aware of, it is the use of volume and pressure water tube steam boilers coal, oil and natural gas are less restrictive , I would like to have a lot of space, but also easy to arrange, in the form of a variety of steam boilers. Water in the steam drum is heated into steam, the heat emitted by the fire in the furnace, is the principle of steam steam boiler. Steam boiler works: 1, heat generated by burning coal in the furnace, the heat transfer by radiation is first absorbed waterwall waterwall Boiling water, a large amount of steam into the drum for water separation (except the DC furnace), separated saturated steam enters the superheater, and continues to absorb the furnace top horizontal flue by means of radiation, convection, heat of the flue gas flue of the tail, and the superheated steam to reach the required operating temperature. Generating steam boilers are generally provided with a reheater, it is used to heat the steam through the high pressure cylinders acting reheater go out of the reheat steam, the low pressure cylinder to continue to generate power. 2, when the pulverized coal fired boiler work, the center position of the flame will impact the amount of evaporation, generally, the lower the evaporation flame kernel, the flame kernel high evaporation amount is small, the center position of the flame will also affect the reheat steam or superheated steam temperature, generally lower the center of the flame in particular superheated steam is then superheated steam temperature to be low, otherwise higher. 3, the arrangement of the burner, pulverized coal fired boiler on, the current embodiment there are opposed wall, more Tangentially combustion, combustion bis Tangentially the like, each have their own characteristics, can not be applied because the same furnace at the same time several above-mentioned arrangement, the steam still can not directly affect the conclusion. 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.
Increase productivity boiler system must first be optimized for verification, including the entire steam system for a complete analysis, and focus on some of the energy waste places. Via check can often find opportunities to save energy, increase productivity, and environmental protection have a positive contribution of. Check includes a steam generation, distribution, use and condensate recovery. The main steam waste requiring special attention place: exhaust gas boiler: boiler efficiency emissions system the most important indicators, the loss of energy is the most important place. Combustion air: general air enters the combustion furnace of the genus room temperature, require a lot of heating energy, i.e., the most commonly used power saving mode using a high temperature exhaust gas to preheat the combustion air of boiler, boiler efficiency can be significantly improved. The fuel / air ratio: Proper oil / gas mixture can only complete combustion, if the lack of air, combustion is incomplete, not only smoky pollution, environmental protests caused nearby residents, and easy carbonized grease gun and boiler heating tubes affect performance. If excess air is formed wasted energy, reducing boiler efficiency. Via the oxygen content of the tail gas can appropriately adjust the oil / gas ratio. Oil-fired boiler exhaust gas which content 3%, i.e., the excess air of about 15%, as the standard combustion control.Free Chat
