Steam boilers are much more widely used than hot water boilers. Hot water boilers are mainly used for heating and providing hot water supply, while steam boilers cover all industries such as industrial and power generation. What are the requirements for boiler boilers for boiler boilers? Undoubtedly safe, stable, efficient, long service life, cost savings, etc., however, these requirements are indirectly or directly related to steam quality. The quality of steam is critical because it affects the stability, reliability and economy of the system, as well as product quality, production power and energy consumption. If the steam boiler user does not pay attention to this, it will definitely lead to a series of follow-up problems for the boiler.
1) Cleanliness: There are rust and carbonate deposits in the steam pipeline, and there may be slag and sealant fragments remaining in the equipment. These impurities may cause jamming and damage to the valves and equipment, and also increase the wear of the pipeline. The way to improve cleanliness is to install a pipe filter, and the filter should be horizontal.
2) Dryness: Incorrect water treatment of boiler hydration, unreasonable boiler level control, and short-term high peak load and other factors will cause the boiler to co-exit the boiler, so that the boiler outlet carries boiler water. When steam is moving in the pipeline, heat dissipation from the pipeline condenses a portion of the steam, adding condensate from the pipeline. The chemical substances and other impurities carried in the condensed water will accumulate on the surface of the heat exchange equipment, affecting the power of the heat exchange equipment, and the accumulated impurities will be fouled on the metal surface of the equipment, resulting in uneven heating of the metal surface and shortened life. In addition, the presence of moisture in the vapor reduces the transpiration of the steam, adding steam consumption; the moisture in the steam will increase the thickness of the water film measured by the heat of the heat transfer, and the rated heat transfer resistance occurs. The addition of a steam separator is a useful way to improve steam dryness, and an efficient steam separator can increase steam dryness to 98%.
3) Purity: There is air in the steam system because the steam that is generated by the boiler still inevitably contains a small amount of air, and there are also air when the pipes and equipment are started. When the system and equipment are shut down, the air is taken in due to the internal vacuum. The air has a very low thermal conductivity and is a poor conductor for heating. The inclusion of air in the steam system will reduce the production capacity of the steam equipment and will also increase the corrosion of pipes, valves and equipment. The most useful way to eliminate non-condensable gases such as air in a steam system and thereby improve the purity of the steam is to install an automatic air venting device in the system.
4) Pressure/temperature stability: In order to ensure process heating requirements, the steam pressure at the steam point should reach the demand value. Together, the steam pressure should not be too high, otherwise steam consumption will be added.
Characteristics of hot water bath hot water vacuum boiler dealer described in Henan fast boiler gas hot water boiler with water in vacuo characteristics having different boiling points at different pressures working environment. At normal atmospheric pressure, the boiling point of water is 100 deg.] C, vacuum gas hot water boiler -0.07Mpa working in a pressure range of the water boiling temperature is lower than the corresponding 93 deg.] C, vacuum gas hot water boiler of the boiler to work under pressure. Combustion temperature of the water rises to the boiling temperature of the boiling water produced the same surface temperature steam, which absorb large amounts of heat volatilization. In this case, the water injected into the boiler heat exchanger, the cold water in the steam tube is an outer tube is heated into hot water then flows, steam is condensed out of the cold water cooled tube heat exchanger into water droplets. This completes the process water circulation in vacuo. 1. In the flue tube mounting closed fins increase the heat transfer effect, so that more concentrated arrangement. 2. Integral with a square configuration, personalized spraying, separation shape appearance. 3, large furnaces can techniques: effective to increase the heat radiation per unit area, to reduce NOX emissions. 4. Pure ensure high boiler water boiler water scaling, oxidation. Fives. All wet back shell using tricyclic structure, static heating, large heat balance. 6, all active control system, no staff on duty. Simple pulse level detection circuit unique structure, reliable performance. 8. Out of the water temperature display is doubled, easy to control operation of vacuum hot water boiler and crumb. 9. High quality multilayer centrifugal glass wool insulation, heat losses are small. Vacuum hot water boiler with three gas-pressure safety protection system: automatic safety explosion relief valve: When the pressure inside the boiler continues to rise, the explosion-proof valve due to excessive pressure and burst, releasing the pressure inside the boiler, to ensure the safe operation of the boiler; a digital pressure switch : imported from Japan digital pressure switches, ready disassembly. Detecting the degree of vacuum changes the boiler, when the pressure is too high, the end of fire; explosion-proof valve automatic safety alarm: In special cases, when the pressure in the boiler becomes slightly positive pressure explosion-proof safety valve controlled vibration alarm, turn off the power boiler.
Operation of the vacuum hot water bath hot water vacuum boiler dealer operation is very simple vacuum hot water boiler is very simple, bank up a fire, dust, water, ignition thanks to this step, when the bank up a fire is the first cleaning, the ash cleaned and then fill the coal bucket to shut the door on coal. Economic and environmentally friendly vacuum hot water boiler is in line with the needs of social development, therefore, vacuum hot water boiler is also welcomed by the people, and its usage is very large, their own strengths vacuum hot water boiler determines its space development huge. Automatic heating, hot water boiler vacuum meter is automatically displayed temperature and pressure, the secondary vacuum hot water boiler 24 hours can be a stoker, a hot water boiler so that the vacuum can maintain a constant temperature all day, so the use of it will be more convenient vacuum hot water boiler thermal efficiency is very high, can quickly heat up, and there is no dust, of course, and there is no smoke, so that the surrounding environment will not cause any harm to make . Vacuum hot water boiler operation is very simple, he has a very novel appearance, this novel shape can play a decorative role, then there is the structure of the vacuum hot water boiler is also very unique.
Cade Shopping Mall is located in central Shanghai Hongkou District, Shanghai Daily larger flow of people in the region. The introduction of Shanghai air pollutant emission standards, bath hot water vacuum boiler dealer flue gas emissions of nitrogen oxide emissions to less than 80 mg / m, Shopping Mall a coal-fired boilers have been used for many years, NOx emissions far super to this request, the urgent need to replace more environmentally friendly low nitrogen emission boilers. Other units through the use of fast Boiler introduction and understanding, determined and fast boiler to achieve cooperation, party fast to their specific needs to recommend one condensing gas hot water boiler of a 4.2MW for heating needs of the shopping center.Free Chat
