Vacuum hot water boiler fuel gas introduced fuel gas vacuum hot water boiler uses water at different pressures, the boiling temperature characteristics differ to perform work. At one atmosphere, the boiling temperature of water is 100 deg.] C, vacuum hot water unit is operating in the pressure range below -0.02Mpa, corresponding to the heat medium water temperature is below 93 deg.] C, the hot water unit working in vacuo under pressure, the combustion temperature of the heat medium water saturation temperature to rise, and the steam generated in the water at the same temperature. At this time, through the heat exchanger (heating or hot water) inside the water, the cold water in the steam tube outer tube is heated in hot water, and passed to the user, and the water steam outside the pipe is cooled when the water is condensed back to water drops heating, thus completing the cycle. Categories; vacuum boiler is mainly classified by the fuel, which can be divided into electrically heated vacuum boiler, vacuum boiler fuel, gas steam boiler, coal-fired boilers in vacuo. Advantages: 1, low-temperature boiler operation under negative pressure, safe and reliable. 2, built-in stainless steel heat exchangers, high heat transfer efficiency, clean water. 3, the built-in rope stream smoke tube sheet, increasing the heat transfer effect, make the structure more compact. 4, imported burner, combustion efficiency, noise, emissions extremely low countries and regions requires a class. 5, a square overall configuration, overall spraying, compact appearance. 6, smoke tube equipped with a helical spoiler, heat strengthen, improve boiler efficiency and reduce operating costs. 7, the indirect heating: main body of negative pressure, the system pressure. 8, large furnace technology: effectively increase the unit radiant heating area, reducing NOX emissions. 9, boiler water with high water, ensure that the internal furnace never scaling, corrosion. 10, boiler and heat exchanger integrated design, saves space and greatly reduce floor space. 11, the use of shell type three return all wet back structure, dynamic heating, heat sufficiently. 12, always run under negative pressure, never inflated the risk of explosion, with safety and reliability atmospheric pressure boiler has unmatched. 13, automatic control system, no special duty. 14, imported burner, combustion efficiency, noise, emissions low. 15, the pulse level detection circuit of a unique structure, reliable performance. 16, inlet / outlet water temperature display makes it easier to grasp the boiler operating conditions and systems. 17, using centrifugal glass wool advanced multilayer insulation, heat loss. Scope: a heat source for heating, ventilation and air-conditioning heat load. Especially suitable for use where the boiler must be set in the building. Choice points: a vacuum hot water boiler The main control parameter is selected rated thermal power, the thermal efficiency of the boiler design, maximum water temperature, fuel type and the like. 2. The thermal efficiency of the chosen design should not be below the lower limit specified in (JB / T10094-2002) "industrial boiler General" (Table 1), and energy-related standards prescribed value.
Selection of vacuum gas hot water boiler buying and selling since ancient times is the opposite process, but we both are indispensable when purchasing selection of vacuum gas hot water boiler should be noted that the selection of methods and techniques, in particular, how can we buy I just to meet the needs of equipment, not a waste, but also small, Xiao Bian gave you the selection of science under the following tips vacuum gas hot water boiler: 1, we must first determine what their needs are for example, I need to use hot water guests, guests can use the hot water 24 hours, this time we need to calculate how many tons of water to meet the needs of so many people, how many people need, then calculate under the premise of this business in accordance with the needs of the best time how much water, how much water most of the time with light. 2, read the information through their own needs or contact the manufacturer search parameters such as my side need to use 2 tons of hot water, burning two tons per hour needed for hot water to customers, and then we have access to matching based on information provided by the boiler plant model is a vacuum gas hot water boiler ZWNS1.4MW of. 3, air consumption calculation boiler example just as we selected two tons gas hot water boiler, a conventional side air consumption per hour is 160, and developed such fast Henan local energy-efficient vacuum gas hot water boiler requires only 140 side, the boiler uses a standard three-cycle to maximize resource savings, of course, more details need to consult the factory for more detailed information. 4, the lower the cost of computing down all the budget we all know that heating water is heated according to the number of degrees to calculate the gas consumption increase or decrease, of course, need the support pipe, labor and other costs of which they need a clearly calculated, calculated rates than, simply, I bought this equipment is used to make money, how much money is the key. 5, the last after-sales service is also very crucial point which needs to be considered big brand manufacturers, because only big business sale is in the country have that with this high-quality after-sales service is very convenient for us of. Well, I am sure the purchase of vacuum gas hot water boiler with better judgment just by the selection of analysis.
Gas heating boiler pressure and how much to open the hotel bath center customers to purchase gas heating boilers, gas boilers for heating pressure is not clear how many, often because they are trouble quite a few jokes, Xiao Bian gave you here a summary of the following gas heating boiler pressure all models, ado first point to hard goods: gas heating boilers can be divided into two WNS and SZS type vacuum boiler type of course, generally speaking only three, in this chapter we highlight WNS type gas Heating boilers, pressure gas heating boilers are mainly five kinds, the most commonly used is 1.25MPa, the eastern part of our standard atmospheric pressure as an example, the standard atmospheric pressure 0.1MPa, the pressure in the boiler is higher than the standard atmospheric pressure of the outside world , so the greater the pressure, the faster the cycle, and because the pressure is so great for the requirements of the material is relatively high, so that, in theory, we can say that the greater the pressure, the better the quality of the boiler! WNS gas heating boilers are mainly WNS-0.5-Y, WNS-0.7-Y, WNS-1.0-Y, WNS-1.25-Y, WNS-1.6-Y composed of five models, but also according to their performance ability of different tonnage different, but there is a little big boiler pressure tends to force stronger. Above Henan party shares fast gas heating boiler plant to provide more official air gas heating problems in boiler pressure you online consultation.
Beiqi Panther car 6 tons of steam condensing one fuel gas steam boiler project has been successfully completed. This series boiler adopt advanced design concepts, using the waste heat of flue gas cascade, with the use of the condenser and the economizer fully absorb the waste heat in the flue gas, the boiler efficiency has been greatly improved.
