Automation design of the integrated boiler room of the administrative building
We have designed the built-in gas boiler in the administrative building. In particular, the working draft ASC automation boiler.
DESIGNING THE AUTOMATION OF AC GAS BOILER
The project was completed on the basis of the design assignment in accordance with the requirements of SNiP II-35-76 "Boiler installations" with amendment 1, SNiP 42-01-2002 "Gas distribution systems", PB 10-574-03, RD-03-10- 2004, RD 03-444-02, RD 12-341-00.
A boiler house with Vaillant atmoTEC plus VU280 / 5-5 boilers (2 pcs.) Is subject to automation. To control the operation of the boiler room in the automatic mode, a cabinet of the boiler room of the CC is installed.
Automation of boilers provides for stopping the supply of fuel to the burners when:
- increase and decrease of fuel pressure in front of the burners;
- lowering the air pressure before the burners;
- extinguishing torch torch;
- increase in water temperature from the boiler;
- lowering water pressure;
- the disappearance of tension.
PROJECT DOCUMENTATION OF ACS BOILER ROOM
At the gas inlet to the boiler room, a gas shut-off valve is installed, which closes in the following cases:
- achievement of CH4 concentration in the air of the room of the boiler room of 10% NKPR;
- Achievement of CO concentration in the air of the room of the boiler room is 95-100 mg / m³;
- the disappearance of voltage;
- upon receipt of the "Fire" signal from the fire alarm system.
The control over the air content of the boiler house is carried out by the RGDMETMP1 (CH4) and RGDCOOMP1 (CO) alarms.
The performance of the boiler room is controlled by the weather-dependent calorMATIC 630 regulator, which is installed in the HQ. The regulator calculates the required load and includes the required number of boilers. At the same time he monitors the uniform use of both boiler units. Additionally, a VR90 remote control is installed, which is located in the largest heated room. The console allows you to control the quality of heating of the premises and change the requirements for the heating of the building (modes of operation of the boiler room).
WORK DOCUMENTATION AK
To maintain the required pressure in the heating network, an electromagnetic valve is installed in the make-up line. When the pressure drops, the valve opens and feeds the return pipe of the heating network to the required value.
An emergency light and sound alarm is provided in the boiler room, in the following scope:
- gas valve is closed;
- minimum gas pressure;
- maximum gas pressure;
- water pressure in front of boilers minimum;
- water temperature in front of boilers at least.
The control devices of the air environment of the boiler house have their own built-in sound signaling devices.
The boiler room is designed to work without attendants. To this end, a cellular warning system, the Xital GSM-12, is additionally installed in the boiler room. The system alerts several cell phone numbers about violations of the boiler room. Signals are transmitted in the same volume as the internal alarm system and additionally the signal of opening the entrance door is transmitted - “An outsider in the boiler room”.
The installation of pressure and temperature indicating devices in the volume is provided in the boiler room, which allows visual monitoring of the operation of all technological equipment units.
Installation instructions.
Installation of devices is carried out in accordance with the instructions of the manufacturers. Cabling should be performed at a height of at least 2.0 m in perforated trays. Cables to the equipment should be carried out in a corrugated pipe. Placement of equipment and cable routes to clarify during installation.
Installation of protective grounding (zeroing) to perform in accordance with the EMP.
Comprehensive testing of automation equipment is carried out in conjunction with testing of process equipment in accordance with SNiP 3.05.07-85.
Our company designs the BOILER AUTOMATION for facilities throughout Russia, but the best prices will be in Moscow, Moscow Region, St. Petersburg, Orel, Tula, Kaluga, Ryazan, Vladimir, Tver, Yaroslavl, Rzhev.
