Urja-Disha is an Extended Design office for all global OEMs & End users, with experience in wide verities of technologies for combustion of fuels for steam generation, Fired heaters, and utilization of waste energy for plant utilities with a track record of delivering highly efficient, reliable, and cost-effective designs in shortest cycle time.

Urja-Disha is only one company having experience of wide verities of dirty & hostile fuels and corrosive, erosive & hazardous waste gases, which call for complete Non-conventional designs& approaches.

You can outsource your complex boiler & waste heat recovery design problems to Urja-Disha which will bring you, substantial savings& improved execution efficiencies at a modest price.

We have developed innovative designs and techniques for a wide range of biomass, industrial waste, and fossil fuels by using various types of Stokers and FBC principles for Power generation, Process application, and Cogeneration.

We design various types of fired, unfired Boilers with conventional & nonconventional constructions for standard and tailor-made applications,

  • CAPACITY RANGE: 0.007 TPH to 200 TPH,
  • PRESSURE RANGE: 10Kg/Cm2 to 110 Kg/Cm2
  • TEMPERATURE RANGE: 100°C to 540°C
  • CODES: IBR 1950, ASME Sec l, BS 1113, TRD, ASME Sec.VIII etc.


  • Conceptualizing boiler configuration suitable for service conditions.
  • Thermal & hydraulic sizing of the system
  • Defining specifications of fuel storage preparation & handling system, Ash handling & storage system.
  • Defining the Specification of pollution control equipment.
  • Preparation of General Arrangement & system layout
  • Pressure parts assembly code calculations & component shop drawings
  • Structural analysis, Foundation loading, component shop drawings.
  • Piping analysis, Support arrangements & Isometric views.
  • Defining control philosophy, P&I Diagram, Cause & effect diagram, Hazop study
  • Preparation of valve schedules
  • Support for vendor data evaluation
  • O&M manual & training.

We are equipped with the latest design & drafting software along with engineering standard and very effective world-class operating processes, it ensures Zero error & Right at the first-time output.

We also extend support for the feasibility study, concept notes, pre-order estimation, troubleshooting, and continual operational guidance by using “IOT” technology.
