Shoe Industry Gas Vacuum Fire Tube Boiler Manufacturers

Because some oxygen corrosion accumulation of dissolved oxygen in water will result in the boiler feedwater process intensifies, therefore, at the same time equipped with the appropriate oxygen equipment should be better control of the intensity of the entire water supply. The oxygen present embodiment mainly sodium sulfite chemical reaction oxygen, this effective method of oxygen can fully reduce the overall corrosion to metal. Meanwhile, some capacity is relatively increased water boiler, may also be employed in high vacuum or low oxygen equipment, a reasonable way is to use hot water boiler air evacuated, forming a gas hot water boiler pressure less than atmospheric pressure will reduce air leakage phenomenon occurs, play a good maintenance effect.

Comfortable life of people is inseparable from the northern winter heating boiler, normal, stable heat source is vital to people's lives. But the attendant is an increasingly serious environmental pollution problems, the implementation of coal to gas policy without delay, using the gas hot water boiler is the general trend. In order to achieve green heating, the National Tourism Administration Service Center decided to phase out the existing coal-fired boilers, the introduction of clean and environmentally friendly gas hot water boiler. Fast boiler with their own strong comprehensive strength and rich experience in the heating industry cooperation gained the trust of the National Tourism Administration Service Center, and ultimately provide a vacuum hot water boiler (T6-2800 2 sets of 2.8MW by fast Boiler ).

Vacuum hot water boiler how much you know? "A" 1. What is a vacuum hot water boiler? A: The so-called vacuum hot water boiler, also known as phase-change vacuum hot water boiler. Refers to normal operation when the internal pressure below atmospheric pressure boiler medium, by heating the cold phase change heat boiler embodiment. (Internal vacuum-tight vacuum hot water boiler body, the heat medium water pressurized combustion, the generated steam heat exchanger for soft drinks, high thermal efficiency, the heat medium water at the factory in disposable infusion process, without replenishment operation. Vacuum hot water boiler unique design, form a safe, stable, etc.) 2. composition principle structure of the vacuum hot water boiler? A: vacuum hot water boiler furnace divided into two parts; the upper half portion of a vacuum chamber (vacuum vapor chamber), which is provided with a tubular interior space of the vapor - water heat exchanger for heating flowing through the heat exchanger Recycled water. The operating principle: vacuum hot water boiler is running, the negative pressure in the vacuum furnace body heat medium water absorbs heat energy released by burning fuel, Boiling water circulating system encounters a stainless steel heat exchanger of the low temperature steam, low temperature steam rises, heating recycled water to users for heating or hot water. Itself is cooled steam condenses into water droplets fall to the surface again after the heating medium is heated, thereby completing the entire cycle. Heating medium water constantly in the body with a closed circulation heating evaporation == == == heat medium condensed water, condensed water without added thus, no danger of burning air. Vacuum hot water boiler using soda condensation heat, all heat exchangers operating condition, soda condensation heat transfer coefficient is the highest. 3. What is a vacuum? A: The vacuum does not mean absolute pressure is zero, as long as the external pressure is lower than, for example, can be called a vacuum: a vacuum when the pot boiler shell is commissioning a vacuum state, and maintain -375pxHg - between 76mmHg.. 4. What is the degree of vacuum? A: refers to the degree of vacuum in the gas lean degree of vacuum in the book, usually with a low degree of vacuum and high vacuum to FIG. High degree of vacuum represents a good degree of vacuum means, a low vacuum degree difference represents the degree of vacuum means. Vacuum degree is lower than the actual value of the pressure of the system shows the atmospheric pressure value, i.e., the degree of vacuum = atmospheric pressure - absolute pressure. Vacuum of international standard units: Pa (Pa). Why The vacuum heating medium water heated hot water boiler in a vacuum state? A: water at different pressures, different boiling temperature which, at one atmosphere pressure (0.1Mpa), the boiling temperature of water is 100 deg.] C, and under a pressure 0.8Kpa the boiling temperature of the water was 4 ℃. Vacuum hot water boiler is operating within a pressure range of vacuum degree of 2.67Kpa ~ 66.6Kpa corresponding saturation temperature is 15 ℃ ~ 85 ℃. Thus, in a vacuum state, the heat medium is easily Boiling water. 6. origin vacuum hot water boiler? A: The basic principles of vacuum hot water boiler was born in 1972, Zurich University. In 1975 the Japanese company TAKUMA Based on this principle has developed a vacuum hot water boiler and patented invention, then gradually popularized throughout the world, this technology has been developed and the development of Korean companies have emerged TAKUMA Korea, China in the late 1980s Some manufacturers have developed vacuum hot water boiler, but due to technical problems, mainly due to gas generated immiscible declining degree of vacuum problems can not be solved electrochemical reaction occurs boiler water and vacuum seal of iron, has not been promoted . 1990s South Korea's manufacturing enterprises to enter the Chinese market relatively late in 2003 about the domestic boiler manufacturers began producing vacuum boilers.

Different specifications hot water boiler service life and its relationship with water tube boiler: A boiler for hot water boiler which saw the words, I believe we are already very familiar with, but, for now, is already a certain the accumulation of knowledge, so, based on this, then, the product will continue to learn and understand, so you can continue the research on the current basis, then, deepen this a boiler familiarity and level of understanding. 1. vacuum hot-water heaters and vacuum hot water boiler, there are differences between them? Vacuum hot-water heaters and vacuum hot water boiler, which are two different things, so they certainly are different, it is impossible to exactly the same. Also, if compare to the control system, it can be said that the former better than the latter, because the vacuum hot water boiler, typically using conventional control systems, and vacuum hot water units, it is better to adopt a control system so the job. 2. The hot water boiler in small and large boilers, which on age, whether there are requirements? Hot water boiler small and large boilers, in which the life, in general, there is a certain time is small from 6 to 10 years, about 15 years is large. However, large-scale boilers in use, some of its widgets, will definitely have to be replaced. Thus, in order to ensure the life of the boiler, and at the same time, can have good results.
