A containerised boiler room is a transportable source of hot water for heating and technological purposes. It is adapted for hot water supplies to be used for heating buildings with potential heating of hot utility water. It is of special advantage in situations requiring the construction of a thermal source in a short time. The boiler room installation requires minimum space and minimum site preparation, minimum electrical installations and system of measuring and control. The boiler rooms are supplied with a burner for burning gaseous or liquid fuels. A standard boiler room set includes a self-supporting steel chimney.
Technical Specifications
A containerised hot water boiler room is completely fitted with machinery and electrical equipment housed in transportable containers suitable for railway transport. The installation is performed on site. The equipment includes the necessary piping, including pumps, a water treatment plant, system protection by means of an enclosed expansion vessel, the respective electrical installations of the system of measuring and control. Each boiler room type is supplied with a self-supporting steel chimney. On clients' request, the system may be supplemented with circulation pumps supplying the heat transfer liquid into the heating network with all related equipment for the preparation of hot utility water. The set also includes a regulative gas station.
MKJ modules with co-generating units based on gas engines or diesel generator sets, added to the containerised boiler room, serve for power generation to be supplied into the distribution network or for the boiler room operation in the case of a non-stable supply of electricity or in locations without access to the distribution network. Waste heat arising during the operation of these units can be used for hot utility water production or supplied into the heating system. The unit is supplied in a separate container of the same type.
The table below displays the basic technical data for boilers with outputs ranging up to 6 MW. Boiler rooms with outputs from 7 to 20 MW are designed individually on request, and, therefore, they are not included in the table. These boiler rooms, in their turn, are not housed in unified containerised modules, but they are transported to the operation site in pieces, in separate module containers, where they are assembled into one block.
Boiler Room Modulation
The required thermal power unit may be obtained by combining individual containerised boiler rooms of a modular system (see below).
Supply and Storage
A containerised boiler room is supplied as a unit, including a case (boiler, water treatment plant, system protection, operating heavy current wiring, system of measuring and control) and a container with a co-generating unit, including a self-supporting steel chimney. Installations for the preparation of hot utility water and a regulative gas station may be supplied on request.

3) added units assure the total power input of the boiler room applying the SAHARA electric heating unit
4) Emission relate to 3% of O2 in dry combustion products at t = 0°C and barometric pressure. The given emission levels may be mainained only provided that the liquid fuel contains (except for values according to CSN 656506) maximally: S < 5 000 mg/kg, N < 1 000 mg/kg, asphaltenes < 3 %.
Boiler rooms with outputs of 7000 to 20000 kg/hour are designed individually on request.
