Boiler thermal efficiency: refers to the ratio of the heat energy output by the boiler to the heat energy input by the fuel during the combustion process. It is an important indicator to measure the performance of the boiler. Generally speaking, the higher the thermal efficiency, the better the boiler's working performance and the lower the energy consumption. We can measure the boiler effiency from following aspects:
η=(Energy output)/(Energy input) X 100%
1. Thermal energy utilization rate: When the boiler converts the heat generated by fuel combustion into steam or hot water, the energy loss is minimal and the conversion process is efficient.
2. Heat transfer efficiency: Whether the boiler can effectively transfer the heat generated by combustion to water through the heat exchange area of the boiler body and the heat exchanger, and convert it into high-temperature steam or hot water, also directly affects the thermal efficiency.
3. Exhaust gas temperature: The lower the exhaust flue gas temperature, the more heat is absorbed by the boiler, and the higher the thermal efficiency of the boiler; if the exhaust gas temperature is high, the heat loss increases and the thermal efficiency of the boiler decreases.
4. Fuel consumption: When the boiler generates the same amount of heat or steam, the less fuel consumption, the higher the thermal efficiency.
5. Emissions: Whether the combustion is sufficient is also a reflection of thermal efficiency. If the boiler burns completely and the combustible gas content in the emissions is low, it means that the boiler uses more energy and has a higher thermal efficiency.
1. Boiler type: According to different application, there are steam boilers, hot water boilers and thermal oil boilers. According to different fuels, there are gas, oil, coal, biomass and electric boilers. Usually the choice of fuel is based on the cost of local fuel.
2. Requirements for basic boiler parameters:
1) Heating capacity: Whether it is a steam boiler or a hot water boiler, heating capacity is a key parameter, which indicates that the boiler can meet the actual heat source demand.
2) Working pressure: Working pressure refers to the maximum allowable pressure of the boiler, which is determined according to the design pressure. When purchasing a boiler, make sure that the working pressure of the selected boiler meets the use requirements to ensure safe operation.
3) Medium temperature: The production process or heating site has clear requirements for the medium temperature, and the temperature that the boiler medium can reach needs to meet the process requirements.
3. Boiler thermal efficiency: boiler efficiency includes three aspects: combustion, heat transfer and waste heat recovery, which directly affects the operating cost. Choosing a boiler with high thermal efficiency means that low fuel consumption, so saving long-term operating costs. In particular, condensing boilers usually have higher efficiency because they can recover part of the heat in the exhaust gas.
4. Boiler safety:
1) Design and material selection: The design and material selection of the boiler must meet national or international pressure vessel standards to ensure that the material is not easily damaged or corroded under high temperature and high pressure.
2) Welding: Welding is a key step in boiler manufacturing. High-quality welding processes and non-destructive testing must be used to ensure that the welds are defect-free.
3) Safety protection devices: The boiler should have complete safety protection devices, such as overpressure protection, overheating protection, water level monitoring, extremely low water level interlocking, and combustion flameout protection, to prevent accidents.
4) Valve quality: Although the valve is a small component on the boiler, the quality of the valve is directly related to the safe operation, operating efficiency and maintenance cost of the boiler.
5. Boiler emission standards: When choosing a boiler, make sure that the boiler complies with local environmental emission regulations, especially the emission standards for harmful substances such as nitrogen oxides (NOx) and carbon dioxide (CO2). Ultra-low nitrogen boilers are a good choice for reducing emissions and reducing pollution. For areas with strict environmental protection requirements, low-nitrogen or ultra-low nitrogen boilers can help avoid unnecessary fines and compliance risks.
6. Boiler size and floor space: Evaluate the overall installation dimension and installation conditions of the boiler to ensure that it can be reasonably installed in the predetermined location.
In addition to the above main parameters, factors such as the boiler brand, quality, and after-sales service also need to be considered. When purchasing, you should choose professional manufacturer with a good reputation and reliable service. At the same time, you should check the relevant quality certification documents of the product to ensure that the selected boiler is of reliable quality and stable performance.
It is very important to choose a reliable and professional boiler supplier, which is directly related to the quality, operating performance, after-sales service and other aspects of the boiler. The following are the factors to be considered when choosing a boiler supplier:
