Pharmaceutical Boilers


A boiler is actually a closed vessel in which water or other fluid is heated for the required purpose. The heated or vaporized fluid exits out of the boiler for use in various processes or heating applications. These pharmaceutical boilers are popularly known as steam boilers. Pharmaceutical boilers are steam generating systems used in various types of pharmaceutical and other applications.
 
Working of Pharmaceutical Boilers
This steam generating device consists of two principal parts: A furnace for providing heat by burning fuel or using electricity and a unit for converting water into steam. The steam is recirculated from the boiler for different heating applications. However the functioning of boilers is different from steam sterilizers or SIP sytem which are used for sterilzation process.
 
Types of Boilers
When it comes to the selection of a boiler, it is mainly dependent on the characteristics of the available fuel, the specified heating output, the location where it will be installed, the required emissions controls and many other factors. Boilers that are commonly used in the pharmaceutical industry are
  • Water Tube Boilers
  • Smoke Tube Boilers
  • Coil Boiler
  • Superheaters
  • Economisers
 
Advantages of Steam Boilers
  • Low steam disengagement velocity, with the ability to arrange the water tube furnace.
  • Flexible combustion space so as to incorporate the type of firing equipment, which is most suitable for a particular fuel and its application.
  • By constructing water wall furnace, less of refractory maintenance is required.
  • Quick steam rising is another advantage.
  • Provision of external furnace in steam boilers give sufficient volume for complete combustion of fuels like coal, oil, bio gas, wood bark, rice husk etc.
 
Features of Pharmaceutical Boilers
  • Usually almost all the branded pharmaceutical boilers are fully automatic
  • Maintenance clean combustion
  • The entire process is almost free of air pollutants.
 
Applications of Boilers
  • Pharmaceutical
  • Paper and Pulp
  • Chemicals
  • Food
  • Refineries
