7 RISK ANALYSIS

Boiler is not filled with water

If the customer heat up in the boiler, which has no water, it comes to the dangerous situations.

Flame created in the boiler starts to heat up the boiler body, which is not cooled and heats it to

the temperature, which achieves temperature of the combustion chamber. Boiler body starts to

heat the insulation, which surrounds the boiler and gradually degrades it by heat. Insulation gets

black and starts to smoke. If its temperature achieves 1 000 °C, it might lead to its burning too.

After the heat degradation of insulations, comes to the degradation of conductors, electric pow-

er supply to the boiler, electric power supply for fan, pump etc. When some of these conductors

get completely melted, it comes to the contact with boiler framework, what leads to the short

circuit. Short circuit might cause burning of the plastic parts in the inside of the boiler. If the

temperature is high enough, it leads to the burning of conductors and plastic parts of the boiler

control. Afterwards, flame might be transfered from the boiler to the area of boiler room. If it was

heated up in the boiler already, boiler is warmed up and then you realize, that the water is miss-

ing, do not fill the water for cooling to the boiler by no means. Filling the cold water to the in-

candescent boiler body would lead to immediate formation of high – pressure steams, what

might lead to the boiler explosion. In this situation, is better to take out the wood out of the

boiler with use of protective gloves, fire poker and ashtray. Extent of these risk situations de-

pends on the amount of fed fuel. More fuel means higher risk.

Safety valve is not functioning

In case, that safety valve of heating system is not functioning or incorrectlly installed (e.g. in the flow

connection and it comes to the exceeding of max. permitted pressure in the circuit (for various reasons

like incorrectly dimensioned expansion tank, too high inlet pressure, too high temperature in the boiler),

it might lead to the dangerous situations. After exceeding max. bearable pressure in the boiler, it comes

to its mechanical destruction and usually in the presence of explosion effect. This effect migh lead to the

loss of property or life. For that reason is very important to install safety valve correctly (riser pipe of the

system) and to check it regulary.

Blocked valve at cooling circuit /insufficient pressure of cooling water

Cooling circuit is an important part of the gasifying boiler. It serves for draining excessive

warmth from the boiler to the waste, to prevent boiler overheating and further dangerous situa-

tions. If is the functionality of this cooling circuit limited or circuit is not functioning and it comes

to the boiler overheating, it leads to the excessive pressure rise in the boiler and risks described

above. Circuit functionality is ensured by thermostatic valve and sufficient pressure of the cool-

ing water (min. 2 bars). For that reason is very important to check the functionality of the cooling

circuit regulary.

Incorrectly installed chimney

Chimney is an important part of the correctly working heating source. Chimney has to be correctly di-

mensioned and fixed to the construction of the building or be its part. If the chimney would not be fixed

enough and it would come to the off – axis movement of the chimney parts, flue gas, which comes out

of the boiler would leak to the boiler room or to the space, where the chimney goes trhough. This flue

leakage is very dangerous, it might cause suffering from mild poisoning by flue gas and also fire. Pay

attention to correct and safe performance of the chimney installation.
