Termo-oil boiler

Within the framework of its ecological program, TTS concerns itself with the utilization of energy that arises from the combusting of biomass. The basic criterion from comparing this alternative source of energy with the clasically used energy system based on the combusting of fossile fuels is to what extent it influences the environment. Whereas the burning of coal, petroleum and natural gas releases carbon dioxide into the atmosphere, which is one of the most significant „greenhouse” gases, the emission of carbon dioxide isn’t increased by the combusting of organic fuels, as practically the same amount the carbon dioxide released in the burning is consumed from the atmosphere during the photosynthetic processes when the organic biomass is created. By the substituting the previous burning of coal with the burnig of biomass, the emission of sulphur dioxide and heavy metals is eliminated.

Description of the Boiler

The boiler is a self-supporting, wholly welded cabinet construction. It serves to combust bio-mass on an overfeed stoker above which a suitably shaped vault gathers countercurrent-wise the layout of the waste gases. This process helps to shorten the time for drying fuel. The bottom part of the boiler is made up of a furnace with a displaceable sloping grate. The grate is governed by a hydraulic mechanism and is cooled by the zonated primary air. On the boiler there is the main oil exchanger. The boiler is furnished with heat insulation covered with steel plate with a plastic surface.

Designed For

Thermo-oil boilers are mainly designed as the heat source of the primary circuit of an ORE. The boiler can also be used for industrial concerns with specialized technological production.

  • Heat output 1 – 10 MW
  • Working overpressure 0,3 to 1,0 MPa
  • Working oil temperature 250 to 300 °С

Advantages of the Conception

The Self-cleaning Abilities of the Boiler:

  •  The grating inclination, the shape of the ceramic vault and the thrust to the ash container without needing to break slag allows the combustion of very fusible material
  •  A large extension grate chamber with the correctly inclined vault removes the significant likelihood of hying Hue ash
  •  The cooling of waste gases in the extension grate chamber at a lower temperature than that of the melting of flue ash prevents the clinkering of Hue ash in the heating tubes of the spiral exchanger.

 

Large through-How capacity of the boiler:

  • A complex system of feeders having a lineal reversible motion causing by hydraulic cylinders forms the transport routes of the fuel.
  • The complete route has large through-How capacity (minimum cross-section 1200 x 280 mm)
  • The transport route is not inclined to blockage (screw feeders or turnstiles, for example, are not able to transport uncrushed bark, and they are inclined to become blocked through the influence of the chords of uncrushed bark).
  • The transport routes are able to transport even a large percentage of non-combustible admixtures (rocks, pieces of steel etc.).

 

Ash Removal:

  • Grate ash falls into a container which is a special mechanism connected directly to the boiler and creates a single space with the boiler
  • There is no closing element which could lower the through-flow capacity of the ash
  • Ash removal can be carried out by an automatic raking transporter to a larger container, such as 10 m³

 

Perfect automation of the boiler:

  •  The combustion has been perfected on the basis of under-pressure in the combustion chamber and through a surplus of oxygen in the combustion products.
  • The fuel feed and the movement on the grate is regulated in accordance with the fuels characteristics.
  • All measured quantities, interventions of the safety equipment and defects are transmitted to the dispatching system.
