Boiler Manufacturers India
The Boiler is connected to the consumers through the steam and condensate piping. When the steam is provided to the consumers, it condensates. It can then be returned to the feed water tank, from where it again is pumped to the steam boiler / steam generator.When the steam condensate is returned to the feed water tank, a pressure reduction is unavoidable and this cause generation of flash steam – typically just after the steam trap(s). This lead to the well-known large condensate heat loss for steam systems, which is actually mostly high-energy flash steam.This loss of flash steam represents loss of feed water, which then require
fresh and pretreated make-up feed water.But it often happens that the condensate is not fully or not even partly recycled because the steam is actually consumed. This increases the demand make-up water. The principle in the fire-tube steam boilers:Its that from the surface of a large volume of feed water, steam is evaporated. This boiling process is heated by the wall of the combustion chamber (the radiant part) and by the exhaust gasses passing through a bundle of so called fire-tubes or smoke-tubes (the convection part). The steam boiler is ideal for small and medium scale industries, studied to obtain maximum safety with the lowest investment.
Design process:
1. Main dimensions
2. Welding details
3. Service, orientation and dimension of each nozzles
4. Details of flange specifications
5. Details of material specifications
6. Design pressure, design temperature, working pressure, working temperature, test pressure, design code, Non Destructive Testing (NDT) details and etc
7. Detail drawings of any components and welding including reference and configuration must be noted on the drawing
8. Full assembly drawing of the boiler showing the essential fittings
9. Each design drawing must be furnished with the information’s as per Appendix 1 (Local)
10. other useful information (if any)
Advantages:
The design combines the advantages of low cost fire tube boiler with its large steam/water drum and consequent low steam disengagement velocity, with the ability to arrange the water tube furnace. With its
flexible combustion space so as to incorporate the type of firing equipment most suitable for a particular fuel and application.Water wall construction of furnace means less refractory maintenance, quick steam rising,
and low carries over. Natural circulation allows safe and reliable working with steady output.Package construction considerably reduces installation costs at the same time eliminates costly civil foundation work.
Provision of external furnace gives sufficient volume for complete combustion of fuels like coal, oil, bagasse, wood bark, rice husk etc. Choice of stationary, dumping or chain grate stoker depending upon the boiler
capacity and fuel availability.
Boilers Advantages of compare with steam generator:
1. Easy to operate – normally no requirement for boiler authorization
2. Rapid start-up and establishing full steam pressure
3. Compact and easy to adapt in the existing machinery arrangement
4. Price attractive – especially at low steam rates.
Salient Features:
1. 3 pass design
2. Wet back design
3. Larger heating surface
4. Capacity Range: 2 T/Hr
5. Manufactured to IBR code
6. Easy access to inner surface of Boiler
7. Large steam space ensure steady supply.
8. Welded construction with 100% radiography
9. Efficiency as high as 88 2% on NCV of fuel of 10,200 kcal/kg.
