As the core facility for heat energy supply, boiler room is widely used in many fields such as heating and industrial production. This article will give you a detailed introduction to the working principle, equipment composition, safety setting requirements and current development trends of the boiler industry.
1. Working principle of boiler room
The working principle of boiler room is mainly based on the combustion of fuel and the transfer of heat energy. The following are the basic steps of boiler room work:
Fuel combustion: The boiler room uses different types of fuels such as coal, fuel oil, and natural gas. These fuels are ignited in the combustion chamber and release a large amount of heat energy.
Heat energy conduction: The high-temperature flue gas generated by combustion is transferred to the circulating medium (usually water or steam) in the boiler through the heat conduction of the boiler furnace wall.
Heating medium: Water or steam is used as a heat transfer medium and flows through the pipe system in the boiler. The heat energy is transferred to the water or steam to increase its temperature.
Energy conversion: The heat energy generated by combustion is eventually converted into mechanical energy or thermal energy and used for steam supply in heating or other industrial processes.
Steam circulation: After the water is heated and converted into steam, the steam is pushed into the heat transfer loop and circulates throughout the boiler system. The steam further transfers heat to the medium to be heated, then is cooled and turned into water, and returns to the boiler for circulation again.
2. Equipment composition of the boiler room
The equipment in the boiler room includes the boiler body and auxiliary equipment.
Boiler body: mainly includes steam boiler, furnace, steam superheater, economizer and air preheater. These components together constitute the basic structure of the boiler, realizing the combustion of fuel and the transfer of heat energy.
Auxiliary equipment:
Coal transportation and ash removal system: including conveyor and ash car, which are used for the transportation of fuel and the discharge of ash.
Supply and induced draft system: including blower, induced draft fan, chimney and dust collector, which are used to provide the required air for combustion and discharge flue gas.
Water and steam system: including feed water pump, water treatment equipment, water tank, steam cylinder and sewage desuperheating pool, which are used for water treatment and steam distribution.
3. Safety setting requirements of the boiler room
The safety setting requirements of the boiler room are strict to ensure the safety of equipment and personnel.
Equipment layout: The equipment in the boiler room should be easy to operate, pass and repair.
Lighting and ventilation: The boiler room should have sufficient lighting and good ventilation, as well as necessary cooling and antifreeze measures.
Prevent water accumulation: The boiler room should prevent water accumulation and ensure that the ground is flat and without steps.
Load-bearing structure: The load-bearing beams and columns of the boiler room should be at a certain distance from the boiler or other measures should be taken to prevent damage by high temperature.
Exit setting: There are at least two exits on each floor of the boiler room, located on both sides. For single-layer boilers with smaller areas, only one exit can be opened.
Door and window setting: The door leading to the outside of the boiler room should open outward and remain unobstructed during the operation of the boiler. The door of the studio or living room in the boiler room should open to the inside of the boiler room.
Lighting equipment: There should be sufficient lighting at the operating location and water level gauge, pressure gauge, thermometer, flow meter, etc. in the boiler room, and equipped with spare lighting equipment or tools.
4. Development trend of the boiler industry
At present, the boiler industry is undergoing a transformation from traditional coal-fired boilers to clean energy boilers.
Clean energy boilers: With the continuous advancement of the country's energy-saving and environmental protection policies, the market share of clean energy boilers such as gas boilers and electric boilers has continued to rise, which helps to reduce pollutant emissions.
Technological innovation: The application of advanced technologies such as water-cooled premixed combustion technology, flue gas condensation heat exchange technology and vacuum phase change heat exchange technology has improved the thermal efficiency and environmental performance of boilers.
Intelligence: The introduction of intelligent and automated technologies makes the operation of boilers more efficient and safe.
Market demand: With the in-depth advancement of industrialization and urbanization, and the improvement of residents' living standards, the demand for thermal energy continues to grow, which has promoted the stable development of the boiler industry.
In summary, as an important facility for thermal energy supply, the working principle, equipment composition and safety setting requirements of the boiler room are all crucial. At the same time, with the continuous development of the boiler industry, the application of clean energy boilers and intelligent technologies will become a future development trend.
