Large bath, bath with hot water boiler as what are the problems, baths and bath are all civilian areas, mainly by providing heating and hot water to the majority of people take a bath for heating, under normal circumstances, there are three main ways of heating their Zhang situations: 1, the traditional coal-fired steam boilers coupled with heat exchangers this method has also been widely used before the second five, but as residents increasingly high demand for this piece environment has gradually withdraw from the stage of history coal-fired boiler currently in the State Department regulations already belong to one of the forced removal and renovation projects, so this method is not suitable for urban populations. 2, the use of biomass pressure hot water boiler utilizing biomass energy field is currently the best known way, the low cost of the boiler, the fuel in the fuel cost is lowest of all, but because of the limitations of raw materials must be equipped with fuel special fireman job, and because biomass fuels, after all, just a lot of places can not be fully developed so popular is the future direction of development. 3, gas-fired hot water boiler vacuum china biomass fired vacuum hot water boiler prices is the new trend in hotels heating sector. Vacuum hot water boiler's heat exchanger is built, it can be directly required hot water temperature. So vacuum boiler for heating and sanitary hot water are no secondary heat exchanger. If for sanitary hot water, then only need to install a hot water tank, and then directly set the heating water temperature can be directly used for water heating. Vacuum hot water boiler for heating and advantages of the hotel Hotel sanitary hot water supply are: ① security: Vacuum negative pressure boiler operation, there is no risk of explosion, very safe, is expressly provided free national supervisory inspection of boilers. ② system is simple: direct water, and heat exchangers can be built multiple, simultaneous heating and sanitary hot water supply. Efficient ③: a high thermal efficiency, thermal efficiency is generally over 94%.
Vacuum hot water boiler on those points we need to know: we usually refer to the hot water boiler is divided according to different ways, have different classification; wherein if in accordance with the boiler pressure points, then, can be divided into atmospheric hot water boilers, pressure hot water boiler, china biomass fired vacuum hot water boiler prices; for atmospheric pressure and we may be more understanding, that comparison, for vacuum boiler maybe not so familiar with, then, as far as it relates to the problem, we have to carry out simple doubts, let us better understand its characteristics, uses, etc. 1. What is a vacuum? Divided into physical vacuum and vacuum industrial vacuum two kinds. Physical vapor space means no presence of particles, industrial vacuum pressure refers smaller than a standard atmospheric gas space, refers to the state of the lean gas, usually obtained with a special vacuum pumping machine, the vacuum in the vacuum are industrial boiler vacuum. 2. What is a vacuum hot water boiler? The so-called vacuum boiler, also known as vacuum phase transition boiler. When the normal operation means, the boiler pressure below atmospheric pressure inside the medium, the cold water is heated by the boiler phase change heat mode. 3. What are the key technology of vacuum boiler is? Key technology is the degree of vacuum vacuum boiler to maintain long-term stability, leakage rate is minimal. 4. What is the vacuum hot water boiler heat exchanger the material is? Heat exchanger disposed in the vacuum boiler SUS304 stainless steel tube. The tubing is difficult to furring, high heat transfer efficiency, will not rust, the heat exchange tubes in a more than ordinary quality restrictions, flow rate. The vacuum hot water boiler temperature control temperature control two ways:? Media outlet water temperature control and temperature control. The default for the water temperature control medium. When the water temperature is selected to control the combustion temperature is automatically adjusted with the water, but if the water medium temperature exceeds set limit on the medium water, burner heating was stopped, the water continues to be lower than the medium by the burner outlet temperature regulator when a temperature of 5 degrees limit status. 6. A vacuum boiler safety device which has a safety device for a vacuum boiler:? ① heat medium water temperature control, may control the temperature inside the furnace heat medium water; ② the heat medium water level control, may control the heat medium inside of the furnace body the level of water; ③ the beginning of the pressure, when the abnormal pressure rise within the furnace operation, the combustion is automatically stopped; ④ hot water temperature control, when the over-temperature water temperature, the combustion is automatically stopped; ⑤ destructive protection: explosion-proof valve. When abnormally high pressure furnace, steam furnace body is released to the atmosphere, to ensure that the unit never danger of explosion. 7. What are the main features ① vacuum boiler pressure vessel does not require local authorities to monitor, installation needed to use;? ② do not need to pay, no good water resistance, long life; ③ low energy efficient, operation and management costs; ④ reduce auxiliary, saving investment; ⑤ high safety performance. 8. Why ① vacuum boiler can be small energy radiative heat loss, the furnace is sealed vacuum vessel, itself has good thermal insulation properties; ② high heat exchange efficiency, the furnace body steam - water heat exchanger thermal efficiency is water - water? 10 times the thermal efficiency of the heat exchanger; ③ small thermal inertia: small boiler size, low water heat medium, the heat capacity is small, small thermal inertia and therefore, the reaction is sensitive to load variation. The boiler is turned on, i.e., 5 to 8 minutes with a hot water. ④ heating surface does not scale, energy saving. 9. Why vacuum hot water boiler blast furnace will never work in a vacuum, not a pressure vessel;? Body sealing of certain heat medium water, air will not burn in any state; the body with multiple self-protection device (anti-overheating, freezing, water shortage bit too high anti-pressure, shock, anti-gas fuel supply enough water, etc.). ? 10, vacuum boiler boiler host large investment it though the price is higher than ordinary vacuum hot water boiler, but it can save a lot by vacuum boiler auxiliary equipment investment: plate heat exchanger, a circulating pump, expansion tank soft water treatment equipment and so on, can also be save the corresponding pipeline installation fees, accommodation fees auxiliary power system control fees, investment is still lower than the average integrated hot water boiler system.
Despite the stable and safe operation of the products, the use of gas-fired steam boilers should be very common. But it's not that you can manipulate it at will. This time we will introduce some excerpts that must be noted when using gas-fired steam boilers. First of all, it is very important to carefully examine the gas steam cooker before starting the boiler. The review process is very important. We must review these parts. For example, whether the gas pressure is reasonable, whether the windshield of the flue gas pipe is open, and whether the vacuum pump is pumping water. Normal. Wait. The boiler can be started only when the equipment is in good condition, and each steam can be operated safely Safety of steam boilers. Second, using shutdown during shutdown should be a very strict process. First, the fire should be turned into a small fire, then slowly extinguished and the burner closed. There should be a lot of summaries about the safe use of steam boilers. If you can pay special attention to the use of so many abstracts, I think the use of steam boilers is very safe to avoid improper use of details. When the water level is lower than the specified minimum water level, but can still be seen in the water level observation instrument, the water temperature is judged to be insufficient, and when the water level measurement item does not measure the water level height, the water level is judged to be seriously short of water. The generalizations of this phenomenon will be listed in The results are as follows: (1) the water level of the drum is less than the normal water level; (2) the warning of low water level is made automatically and the signal light is on; (3) the steam temperature of superheated steam is increased; (3) the temperature of superheated steam is increased; (4) the water supply is abnormal, which is lower than the value of steam flow; (5) the temperature of exhaust water vapor is increased.
Around the low nitrogen emissions and thermal efficiency of the boiler regard, Jiang Zuojun, who are very interested in the company's showroom will watch the animated presentation, could not help nodding in approval, other fast boiler in a variety of achievements in the industry made a lot of money and gave high praise and affirmation. Subsequently, a pedestrian visited the lab to clean the boiler group, for the constitution and the implementation of the Group's research laboratory work was questioned and understanding.
