    5. FUEL 5.1. FUEL The basic fuel for heating boilers of SAS NWT type is a black coal for energetic applications of the nut grade (acc. PN-91/G-04510 type 32.1 class 24/12). That type of fuel guarantees that the declared power may be achieved.

    5.2. ALTERNATIVE FUEL The alternative fuel for coal heating boilers of SAS NWT type is a mixture of the black coal grades as follows: 70% of coal the nut grade ( class 24/12 acc. to above mentioned norm) and 30% of coal the fine coal grade (class 21/15 acc. to above mentioned norm). These boilers are also fit fir combusting long flame fuels, such as: brown coal and wood in different forms, e.g.
  • Page 8 6.2. BOILER’S ARRANGEMENT Special foundation for boiler is not required, however it is recommended to put it on concrete platform 2 cm high, but it may be also practiced to put it directly on the fire-proof floor. Boiler’s layout should ensure easy and safe operation of such elements, as furnace, ash box and fuel loading, and do not obstruct cleaning operations.
  • Page 9 In the front upper part of insulation there is G 1” connector for thermometer. If thermometer will not be mounted on it, this connector should be plugged. Boilers of SAS NWT type may work with gravitational or forced water circulation. If installation is provided with circulation pump, than on feeding/return pipe the differential valve should be installed.
  • Page 10 Set the required temperature on the controller. BOILER SAS NWT IS THE LOWER COMBUSTION TYPE AND SHOULD NOT BE FIRED UP FROM THE TOP! During fire up process the boiler should be monitored until it gets feeding water temperature of 45°C.

    Temperature of water leaving out the boiler depends also on thermal characteristic of building, e.g. construction materials, in particular the insulation one. With boilers of SAS NWT type, regulation of combustion intensity and heat capacity, depending on weather conditions, is done by microprocessor controller.
  • Page 16 For the period of brake time, water should not be drained out of boiler and installation. If boiler’s stopping took place in emergency conditions, glowing fuel shell be removed into metal box and taken out of boiler room, or alternatively the gloving fuel may be covered with sand.
