How to guarantee steam quality of steam boiler

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.

Second, the overall structural design of the china vacuum hot water boiler for sale is more scientific and rational, has a smaller overall footprint advantages in the boiler room building can greatly reduce floor space, a furnace body heat exchange can effectively shorten the warm-up period and reduce energy waste.

What hospital do with the gas boiler? Gas-fired boilers for hospitals is generally used to supply steam to sterilize or to provide hot water for heating the hospital, a gas boiler to provide steam and hot water simultaneously to meet different needs, but it needs to install heat exchangers achieve. Hospital of Zhengzhou City, a large, began to replace coal-fired boilers to gas-fired boilers to meet the energy saving policies. Hospital which model is more appropriate Gas boiler Xiao Bian recommended several:? WNS4-1.0 / 184-Y / Q, SZS10-1.25 / 350-Y / Q, both gas-fired boiler is a single drum, a double boiler tube, the hospital according to the actual amount of steam heating area, need to use to determine the tonnage of the boiler. WNS and SZS different models, provided with a vapor pressure hot water temperature is also very different. Make sure to choose to use that does not waste as needed. Square Co., Ltd., Henan fast: Henan square quick Co., Ltd., founded in 1945, specializing in the design and manufacture of industrial boilers more than 70 years, fast Henan party shares from the beginning of the coal-fired boilers, circulating fluidized bed boiler experience, waste heat boiler , raw materials development and manufacturing of boilers, to the current fuel gas boiler with a vacuum if you are interested in our products or have questions, you can communicate with us online by clicking the online consultation.

Our emphasis on increasing green, local governments also boiler operation produces nitrogen oxides and smoke emission requirements become more stringent. Fast boiler followed by the national trend of development, deepening of cleaning boiler product design and development. Lulu as a representative of business development of the national beverage, and hope to find a set of boiler energy conservation and clean in one, for drink production process of fermentation, sterilization, drying, curing and other processes. After many visits and market research, in October 2017 and entered into boiler fast boiler purchase contracts, purchase two 10 tons of steam and a whole 20 tons of steam condensing steam boiler. The two sides this cooperation is the other quality fast condensing gas boiler highly recognized, has proved a powerful strength fast boiler in the boiler production and service of gas condensate from the side.
