Roof boiler rooms

Roof boiler plants are designed for hot water supply, heating and ventilation of apartment buildings, as well as industrial buildings and facilities.

Roof boiler systems are placed on the roof of a building or other structure on a specially prepared roof area or mechanical floor. This method of boiler room location is determined by financial viability and economy of the aboveground area (in comparison with stationary boiler houses). It should be noted that not any building can be heated by a roof boiler plant.

The benefits of roof boiler rooms

Due to its location roof boilers have a number of advantages over other boiler designs:

  • economic benefits due to saving space at the facility which give the opportunity to install a separate boiler house or other construction
  • no need for long utility networks
  • easy installation and operation
  • energy efficiency due to the close location to the consumer and low heat loss on the main pipelines

Construction features of roof-mounted boiler plants

The use of boiler plants on the roof determines some restrictions:

  • power (up to 3 MW)
  • the height of the heated building (up to 26.5 m) (it is possible to place the roof boiler rooms higher in special agreeing with the regulatory authorities)
  • water temperature (up to 115°C)
  • steam pressure (up to 0.07 MPa)

Also, it is forbidden to install roof boiler rooms on some types of buildings, for example, above production facilities (where there are more than 50 people at a time), at school and health institutions, that is, close to people.

Roof boiler units are manufactured and supplied in full factory readiness in-frame or in framed insulated blocks-modules with the equipment already placed inside. At the operational location it remains to plug into the heat networks and to carry out start-up and commissioning.

Boiler operation control is fully automated. The control panel is located in the dispatch center.

The roof boiler plant equipment configuration

The roof boiler equipment configuration is determined by the requirements for the power and the fuel type (gas, liquid fuel). So, the main equipment of roof boiler houses is as follow:

  • steam or hot water boilers
  • water heaters, heat exchange equipment
  • heating and hot water supply pumps (network, circulating-water and others)
  • water treatment system to reduce the corrosive effect of water on equipment and pipelines
  • piping valves (gas pipelines, liquid fuel pipelines, water and heat supply pipelines)
  • automatic regulation, control, protective and alarm devices
  • chimney
