Boilers

Hot water boilers and boilers for the production of water vapour under high pressures are considered to be steam boilers. As a generic term, boiler is used to denote steam generators and hot water installations. In the industry there are two types of boilers; the steam engine boilers and fire tube boilers.

Steam engine boilers are used to generate steam to operate steam turbines.In current utility steam boilers, up to 3,600 t steam is generated per hour under pressures of 300 bar and steam temperatures of 620 °C.

Fire tube boilers are often used in small and medium-sized industrial plants, for example in the paper or food industry, where small and medium-sized mixtures of hot water or water vapour are required at low pressures. These boilers are used in the technical building appliances of large complexes, such as hotels, hospitals etc.

Purpose of insulation

Insulating boilers has the following purposes:

  • Reduces heat losses and increases the efficiency of the boiler
  • Guarantees protection against contact by minimising the surface temperature
  • Prevents heating of the compartment air in the boiler house, which guarantees an acceptable working.

Products

Applying load bearing mats such as ProRox MA 520 ALU is a proven solution in the insulation of boilers with a surface temperature up to 300ºC. The load bearing mats are easily mounted onto the horizontal, cylindrical boiler surface and are easily fastened to the boilers with metal straps. Metal spacers, which always create thermal bridges, can be omitted.

ProRox wired mats have proven invaluable in the insulation of utility steam generators over the years. They are flexible and can be easily mounted onto the various geometries or surface structures. ProRox wired mats are non-flammable, have high maximum service temperatures and exhibit a low degree of thermal conductivity across the entire temperature range.
