Water boilers for heating installations

Table of Contents

Basic energetic parameters are structured in the table (p. 8) and on the

drawing (p. 9 ).

Heating boilers of SAS MULTI type are driven by fuel:

In the fuel supply automatic mode:

basic fuel for

boilers SAS MULTI type,

grade. Its granulation is 5 – 25 mm (energetic pea coal, washed, 31.2 type). The

coal of fine coal grade and coal of thicker than given granulation

applied. This type of fuel may hinder feeder operation.

Basic parameters of the coal for SAS MULTI type boilers are placed:

Granulation

Humidity

Ash content

Ash melting temperature

Low coal swelling

burner

Volatile particles content

It is recommended to use coal which is prone to agglomeration (coking), although it is

good caloric properties, higher losses of the coal in ash may occur.

Besides that, some of highly coking coals may cause the tip of screw feeder burn off.

Note: fuel bunker should be supplied with a coal free of water, without

excessive volume of the fine fractions and foreign bodies.

In particular, during the loading or fuel refueling, attention should be paid if lumps of coal, pieces of wood,

stones or other unwanted objects are present, as feeder gear may be blocked once affected (it may be blocked

once affected (it may load to cut the motoreducer)
