What should be equipped with safety accessories boiler safety valve, explosion-proof doors, security seal, a low water level control alarms. Safety devices: a flow meter, pressure gauges, thermometers, fortune controller, water table and protection devices. Protection device: low water level alarm, low water interlock protection, vapor overpressure protection of the alarm and interlock devices, process control and ignition flameout protection devices. A safety valve the pressure in the boiler is controlled within the allowable range to ensure the safe operation of the boiler. When it exceeds a predetermined value, it can automatically open the exhaust steam, pressure relief, to prevent over-pressure boiler accident. Pressure gauge to measure the actual size of the boiler meter, pressure gauge value according fireman art, adjusting the lift of the boiler pressure, the boiler to ensure safety in the allowable working pressure. The role of water table is indicative of the high and low water level in the boiler, the water level in the boiler fireman help dynamic monitoring personnel to the boiler water level control in the normal magnitude of the boiler to prevent the occurrence of lack of water or full of water accidents. When the role of the vent is mild explosion in the furnace or the flue, can open their own relief, to avoid accidents and expand occur.

Steam boiler is one of the indispensable devices in the pharmaceutical industry, decoction of Chinese medicine, medicine drying, sterilization, cooking gum, drying, tabletting and capsule production processes, a large amount of steam will be used. West Libang Pharmaceutical Co., Ltd. is a pharmaceutical research and development, production and sales of high-tech enterprises, the existing anesthesia, cardiovascular, child immunization, pharmaceutical raw materials, pharmaceutical excipients, nutrition series of six automated production lines. With the increasing strength of China's environmental protection, some high-pollution devices are making the transition to clean environmental protection. Libang Pharmaceutical respond positively to national coal to gas policy, decided to change the existing coal-fired boilers to clean better gas steam boiler. Fast boiler with strong comprehensive strength in the field of clean energy, Libang Pharmaceutical after conducting comprehensive consideration, determined to cooperate with the fast boiler. The two sides further understanding, party fast technical engineers according to production needs state power, and soon its development of specific solutions for its recommendation of a 6 tons of steam condensing gas steam boiler (WNS6-1.25-Y.Q).
Gas boiler target pressure fluctuation of issues related to the target pressure is the vapor pressure of the gas boiler size needed to get the actual site. To pay attention to the following points: 1, the steam pressure is directly related to the quality of steam, steam pressure 1.0Mpa as a watershed, 1.0Mpa or less, the lower the vapor pressure, the worse the steam quality; 10Mpa above, the higher the vapor pressure, the worse the quality of steam . Meanwhile, the boiler load can directly affect the quality of steam: 2, at a vapor pressure of boiler water salinity and certain conditions, the boiler load increases, the amount of water vapor with a small amount tends to increase. If you overload the boiler is running, it will be a serious deterioration in the quality of steam. 3, the steam containing impurities damage caused by excessive heat, reduce the heat transfer capability, it will wall temperature exceeds the critical limit temperature to allow the metal, leading to over-temperature burn smoke tube. Steam ranging from the endothermic reduction, overheating temperature decreases, the exhaust gas temperature increases, reducing boiler efficiency. First, a common cause pressure fluctuations: 1 different manufacturing lines; 2 boilers used in combination can cause pressure adjustment... II Solution: modified if necessary according to the actual pressure, it should be carried out within a small range stepwise correction, e.g. 0.02 adjusted up or down. Third, the professional advice: It is recommended to run at a higher pressure, increasing the pressure relief valve at the end. High-voltage transmission principle, the use of low pressure. 1, the advantages of the high pressure steam conduit delivering steam A. The small-diameter, heat loss;. B steam pipe lower costs, support costs less, low labor cost;. C lower cost insulation pipe;. D reduced pressure by using point may be obtained drier steam;. E high pressure boiler is easier to achieve optimum operation, higher operating efficiency;. F increase the heat storage capacity of the boiler, is easy to handle changes in load, and to reduce the priming with water possibility. 2, the low pressure steam pressure reduction A. advantages may be provided in a greater proportion of the steam latent heat;. B reducing the pressure of condensed water can be reduced calories, reduced secondary steam;. C under reduced pressure vapor after having a higher dry degree.
The extra volume created by this expansion has to go somewhere or pressure will dramatically increase, such as when water is heated in a closed system. A good indication of thermal expansion is when the T&P valve releases about one cup of water for each 10 gallons of heater capacity with each heating cycle.Get A Quote
Oct 12, 2016 · In contrast, a hot water boiler will typically require an expansion tank, a circulator, and a flow check valve. Most importantly, a hot water boiler will require a motorized pump. Cost of Implementation. The cost associated with steam boiler vs hot water boilers are approximately the same.Get A Quote
A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (72,000 kPa or 1290 psi) but, at pressures above this, it is more usual to speak of a steam generator.Get A Quote
Understand that for hot water heating boiler expansion tank sizing calculations, you need to take the system volume, temperature differential, etc. into account. But with a house so large with dozens of radiators & seemingly miles of piping, I can't begin to imagine how you could calculate the total volume.Get A Quote
The water temperature determines the capacity and how fast the heat comes from the baseboard heaters. In properly designed systems, water temperature should be between 140 and 180F. Commercial boilers and some newer residential units, have a control that varies the water temperature (called a Boiler Reset) with the outdoor temperature.Get A Quote
If a steam/hot water boiler has an output rating of 2,350 lbs/hr steam, when it is designed for a hot water application (for example, at 40 psi), the "Minimun Relief Valve Capacity" rating on the ASME plate must be in MBH.Get A Quote
NOTE: Insert boiler output capacity or indicate in boiler schedule. Select boiler design working pressure, operating pressure, operating temperature, and return water temperature and indicate in boiler schedule on drawings. ***** Boiler must be suitable for installation in the space shown with ampleGet A Quote
The rated heat capacity of boiler refers to the heat amount per hour in hot water of a long-term and continuous operating hot water boiler, that operates at rated return water temperature, pressure, and the specified circulating water. The unit of it is MW. 0.7MW heat from hot water boiler equals to the heat of 1t steam from steam boiler. PressureGet A Quote

The Boiler Horsepower (BHP) is the amount of energy required to produce 34.5 pounds of steam per hour at a pressure and temperature of 0 Psig and 212 o F, with feedwater at 0 Psig and 212 o F. A BHP is equivalent to 33,475 BTU/Hr or 8430 Kcal/Hr and it should be noted that a boiler horsepower is 13.1547 times a normal horsepower.Get A Quote
For high pressure boilers with a combined bare tube and extended water-heating surface area exceeding 500 square feet, one safety valve is required if the design steam generating capacity of the boiler is less than 4,000 pounds of steam per hour.Get A Quote
Sep 25, 2014 · The code reads, Capacity certification tests of safety relief valves for water heating and hot-water supply boilers shall be conducted at 110% of the pressure for which the valve is set to operate.

Jun 18, 2014 · The boiler has to heat all that water from room temperature to, let's say, 180 degrees. That's going to take some doing if there's a lot of water in the system. Consider an old gravity hot water system, for example. You could have six- or eight-inch pipe in some of those old beauties and that represents a bodacious amount of water.Get A Quote
