Deluge Suppression Systems

Deluge suppression systems are systems where all sprinklers that are connected to a water piping system remain open,i.e., the heat sensing element is removed or designed specifically that way. These systems are designed and used for special hazards where there’s a concern for rapid fire spread, as they offer a simultaneous water application over the entire hazard. At times they are installed in building openings or personnel egress paths to slow the travel of fire (e.g. openings in fire rated walls).

Water won’t be present in the piping till the system functions. Due to open sprinkler orifices, piping will be at atmospheric pressure. To stop supply pressure from forcing water into the piping, deluge suppression systems or deluge valve is then used in the supply connection.

Because of heat sensing elements in automatic sprinklers will have been removed, the deluge system should remain open as communicated by the fire alarm system. The kind of fire alarm instructing device is mostly selected based on the nature of the hazard like heat detectors, optical flame detectors or smoke detectors. The instructing device communicates with the fire alarm panel, which in turn instructs the deluge valve to open. Activation can be done manually as well, depending on the system objectives. Manual activation is normally done through a pneumatic or electric fire alarm pull station, which instructs the fire alarm panel, which in turn instructs the divulge valve to open therefore allowing water into the piping system. Water will simultaneously flow from all sprinklers.

Deluge fire sprinkler systems are different to standard fire sprinkler systems in that all nozzles being used in the system will be open and when water is allowed to enter the system, it flows from every discharge device. Because of this, such types of systems are mostly found in industrial type hazards across India as they require water application over a large hazard area. A deluge valve controls the water as it doesn’t allow water into the piping system until such a time when it is required.

A detection system incorporates the use of flame, heat or smoke detectors is used for opening the deluge valve in the event that fire or any of its combustion products are detected. Every system piping will be filled with water which will discharge from nozzles and sprinklers used in the system. To add to the application of water, certain deluge suppression systems incorporate foam concentrates to mix with water and create a form-like solution which then provides a protective foam blanket to control a fire.

Deluge suppression systems are widely used across different industrial sectors in India, but mostly by industries that specialize in chemicals, explosives, and petrochemicals and they are highly rated fire hazard zones.

Automatic Sprinkler System Design Factors

Irrigation and water systems for a residence can prove to be an essential mechanical aspect of any garden or lawn. Designing a proper automatic sprinkler system for your home is something that should be done with great care and technical know-how. In India, there a number of companies that provide this service for homeowners or companies with areas that require watering.

Automatic Sprinkler System Design

Planning an efficient automatic sprinkler system for your property requires you to note a number of essential things. One needs to correctly understand the design capacity of the sprinkler system and just how much water is actually available for the sprinkler system to utilize. Often times, irrigation systems in India are done using the public water supply. A number of things should therefore be checked, these include:

  • Check the water pressure (PSI). Attaching a pressure gauge to the external faucet nearest to the water meter can do this. You should ensure that no other water in flowing within the house. Turn on the water supply and take a record of the number indicated.
  • Determine the water volume available for the sprinkler system
  • Also, using an appropriate system design capacity chart, locate your own sprinkler system design capacity and static pressure.

After checking these basic things, then you can proceed to installing your sprinkler system.

  • Do an appropriate plot plan by indicating and sketching the location of your house, taking note of all trees, lawns and fences around the house.
  • After determining the water pressure and volumes necessary, the next step is to select the sprinkler head. There are three main types and these include; rotors for large areas, rotating steam spray sprinklers and small area sprinklers.
  • After understanding the reach and capacity from choosing your sprinkler heads, you can design where you want to locate your sprinkler heads around your lawn. Sprinkler heads usually come with specifications on their reach so be sure not to place sprinklers far apart so that everywhere on your lawn can be watered. Sprinklers can also be divided into zones if the yard is quite large.
  • Properly ensure all points of connection are in proper correspondence with each of the specifications needed, including pipes and valves. Most professionals would recommend PVC pipes because of the constant water pressure from the backflow preventer to the zone control valves.
  • Run a proper system installation ensuring the wires for the main control are all connected.

Automatic sprinkler systems are quite technical to install and you should contact the help of an experienced professionals. Most homes in India have small watering areas so the workload may not be so much of an undertaking. For larger areas such as fields and parks, a proper technical team should be employed to properly take care of all the technicalities that may arise on the job. It may also not be a one-day job so patience is required in order to sort out all the small aspects to ensure your automatic sprinkler system is working perfectly.

Simulation & Analysis Of Industrial Crystallization – Custom Simulation India

Crystallization is a process commonly used throughout India where dissolved products from the solution are recovered to an acceptable level of purity. There are two processes used for crystallization –evaporative concentration (eg. Sodium chloride) and adiabatic cooling (eg. Sodium sulphate).

Various systems are used throughout India in order to conduct industrial crystallization. Custom simulation is often found within large systems and there are even operators and other equipment that are capable of performing this process.

Tank crystallizers are still commonly used throughout India. The saturated solutions are placed into the tank and allow to cool. The original liquid is ultimately drained and the crystals are removed. While labor costs are generally high using this method and the size of crystals are difficult to control, it is still one of the more affordable options because some of the larger piece of the equipment are cost prohibitive.

Crystallization takes place within cooling systems as well as evaporators. It is also critical that there is simulation and analysis of the industrial crystallization in order to learn more about the crystals as well as the overall viscosity of the solution.

New tools and techniques are being introduced in order to establish custom simulation of this industrial crystallization. After all, companies and chemical factories of all sizes look to maximize profits by operating in the most efficient way possible. When there is any kind of bioprocessing, it is important to analyze all aspects of the process – and this includes industrial crystallization.

Various simulation tools can be used throughout process development and ultimately lead to better plant operation. Once custom simulation in India is established, it is possible to learn more about the industrial crystallization, specifically of the different liquids that are used.

Computational fluid dynamics (CFD) is a recent development, though it is still just beginning to enter the Indian marketplace. By taking advantage of this level of technology, it is possible to obtain more characteristics of the industrial crystallization, which can also lead to learning more about the mixing, the distillation sequences, the purification levels, and the ability to review methodologies.

No company or plant should operate without taking into consideration the overall analysis of industrial crystallization, and India is no different than any other country. While water is not always readily available or as clean as it needs to be, there are various solutions that can be placed in the water – and industrial crystallization can take place for a method of purification. It’s one step that is critical in ensuring that companies are using the best product, regardless of what their end goal is.

Simulation and analysis can help to determine equipment, process flow, and even assist with estimating operating costs. It’s just one of the many reasons that it needs to be done, and done efficiently.
