Automation.

The boiler house of the Central Ural production base "xxxxxxx" is equipped with 2 Viessmann Vitoplex 100 boilers with a capacity of 405 kW each with a gas burner.

The safety automation system ensures the cessation of gas supply to the burners in case of emergency situations, namely:

when the burner flame goes out;

when power supply is stopped;

when the gas pressure upstream of the gas burner is reduced or exceeded;

at reduction of air pressure upstream the gas burner;

at increase of water in the boiler more than 90 ° С.

if there is no water in the boiler;

at actuation of protection against short-circuit currents and overloads;

in case of fire in the boiler room.

When one of the protections is activated, the solenoid valve installed on the boiler gas pipeline is closed.

The burner thermal power is controlled automatically from the boiler thermal power controller.

Solenoid valve installed on common gas line stops gas supply at:

gas contamination in the boiler room of CH4 and CO (at ССН4=12±8% of NKPR, SSO of =100mg/m3)

increasing the gas pressure in the header upstream of the boiler,

decrease and increase of coolant pressure,

when the power supply is stopped.

The boiler room has light and sound alarm:

gas contamination of room CH4> 10±5% of NKPR,

gas content of CO room > 20 ± 5 mg/m3,

lowering and increasing the pressure of natural gas before the burner,

decrease and increase of coolant pressure,

burner accident: flare failure in the burner and reduction of air pressure before the burner, fire in the boiler room.

Alarm devices are mounted on the boiler room automation board. In case of an accident, the light alarm is output to the boiler room automation panel. The sound alarm is duplicated by a sound signal in a room where maintenance personnel are constantly present.

7. Heating and ventilation.

Heat losses through building structures are compensated by heat emissions from cast iron radiators connected to the pit circuit. Radiators are installed under light openings and near external walls. Ventilation of the boiler room is natural. The volume of supply air is determined by 3 times air exchange per hour plus the flow rate of air required for combustion. Air inflow is carried out through two blocks of louver screens 600x400 located in the lower part of the entrance door. Exhaust - through two baffles Ø 400.
