In addition, biomass energy is also the most widely used renewable energy source. Although the application of conventional coal-fired thermal power boiler co-fired biomass fuel has developed quite well abroad, it has positive and significant benefits for greenhouse gas emission reduction. But the countries that burned the creatures There are differences in quality, and the method of co-firing is closely related to the conditions of raw materials, equipment status and policy content.

In view of the limited quantity and source of domestic biofuels, under the pre-determined conditions of “no modification of equipment” and “how much to burn”, the existing units are co-milled and burned with raw fuel and evaluated as a feasible solution. The capacity or function of the feed system, pulverizer and burner is generally considered to be the main limiting factor for the proportion of co-firing, so countries are still pursuing further breakthroughs in these restrictions.

In order to solve the problems and limitations mentioned in the prior art, the present invention provides a furnace apparatus including a feeding system, an operating system, an exhaust system, and a discharge system.

Wherein, the action system is connected to the feeding system, the action system comprises a first silo, a second silo, a working furnace and a blower, the first silo is connected to the feeding system, the second silo Connected to the first silo, the working furnace is connected to the second silo, and the blower is connected to the working furnace.

The exhaust system is provided with an exhaust pipe, which is respectively connected to the first silo, the second silo and the working furnace, the filtering system is connected with the working furnace, and the discharging system and the filtering System connection.

The invention selects carbonized biomass fuel which is close to the characteristics of coal fuel, and can directly reduce the influence of the co-firing process on equipment operation and personnel operation.
