Hot air furnace classification

Biomass hot air furnace according to its use is roughly divided into two categories: one is biomass thermal hot air furnace, the other is biomass electric hot air furnace.

In fact, the principle of the two is basically the same, is to burn biomass fuel to obtain energy, but the first directly to obtain heat, the second heat into electricity. In these two kinds of hot air furnace, the first is now the most widely used, relatively mature technology.

If further subdivision, the first type of hot air furnace -- biomass thermal hot air furnace, can also be divided into three categories:

Category I: small biomass thermal hot blast furnace. This kind of hot air furnace USES solidified or gasified biomass fuel to provide thermal energy in the form of hot water. The disadvantage is that, the energy loss is big, the fuel consumption is big, the heat energy supply quantity is low, cannot satisfy the user of the heat energy demand is big, the target of this kind of hot air furnace is the heating of single rural family and the domestic hot water supply.

The second category: medium - sized biomass thermal furnace. This type of hot blast furnace mainly USES curable biomass fuel to provide hot water or steam. Its advantage is that the technology is relatively mature, the energy loss is small, the heat energy supply capacity is strong; The disadvantage is that some hot air furnace fuel coking, supporting design is not reasonable. The "spiral wind-wing burner technology" of shandong hill biomass energy co., ltd. has solved the problems of insufficient combustion and coking of medium biomass hot air furnace.

Category three: large biomass thermal furnace. This kind of hot air furnace has no actual product, mainly because the existing technology is not perfect, and the national policy for biomass to replace coal is not sound, therefore, only stay in the concept. What it emphasizes is a kind of centralized management, centralized control of thermal engineering, hot air furnace only as one of the equipment, to ensure the normal operation of the whole biomass thermal engineering, therefore, it has high requirements on fuel, combustion technology, supporting technology, relevant policies.

Fuel analysis

1. The sulfur content of biomass fuel is mostly less than 0.2%. It is not necessary to set up gas desulfurization installation when extinguishing, which reduces the cost and benefits the maintenance of the environment.

2, the use of biomass hot air furnace extinguishing equipment can be the fastest speed to complete the large-scale reduction of all kinds of biomass resources, harmless, resource-based application, and low cost, so biomass direct extinguishing technology has a good economy and development potential.

3. The carbon dioxide released by biomass extinction is roughly equivalent to the carbon dioxide absorbed by its growth through optical coordination, so it can be regarded as the zero emission of carbon dioxide, which helps to alleviate the greenhouse effect;

4, biomass extinction products are widely used, ash residue can be integrated application;
