Biomass boilers are used in a wide range of scenarios, including industry, heating systems, agriculture and power plants. The passage will briefly introduce biomass boilers from the following aspects.
1. Definition
Boilers that use biomass energy as fuel can be divided into biomass steam boilers, biomass hot water boilers, biomass hot air furnaces, biomass thermal oil furnaces, etc.
2. Advantage
- Multi-purpose: Can be used for heating, cooking, boiling water, and bathing simultaneously.
- Efficient Conversion System: Low start-up heat transfer temperature and fast heat transfer speed.
- Low Installation Cost and Safe Heating: The equipment is universal and compatible with existing heating systems, using water circulation to achieve heating. The fuel source is abundant and inexhaustible, including materials like rice husks, corn stalks, rice straw, and wheat straw.
- Environmentally Friendly: With low working pressure, biomass boilers are suitable for heating boilers, greenhouse heating, large-area heating, and use in small to medium-sized restaurants. They can be used year-round, regardless of the season.
3. Problems
- High-Temperature Corrosion: Since biomass fuel contains a variety of salts including chlorides, the flue gas produced by combustion is highly corrosive. High-temperature corrosion will occur on the heating surface tubes in the third and fourth stage superheater areas.
- Low-Temperature Corrosion: If the air preheater is positioned directly in the rear flue, the temperature of the pipe-wall at the outlet can reach the acid dew point of the flue gas, causing severe low-temperature corrosion.
- Ash Accumulation: The area of heated surfaces is influenced by factors such as flue gas velocity, dew point temperature, and structural arrangement. The area of heated surfaces is influenced by factors such as flue gas velocity, dew point temperature, and structural arrangement.
4. Development Prospects
Biomass boilers have significant international development potential, driven by policy support from various countries, technological advancements, environmental protection requirements, energy security considerations, economic benefits, and market demand. The biomass boiler market is expanding rapidly, particularly in the EU, North America, and the Asia-Pacific region. The global demand for clean energy and increased international cooperation are further accelerating the adoption and application of biomass boiler technology.
