Problems solved by technology

[0005] But because the ash melting point produced by bagasse combustion is low, and the grate surface temperature of the existing boiler is high, the ash and slag are easily melted on the grate surface, and the tuyere on the grate surface is easily blocked, which is not conducive to the bagasse burning. It is also not conducive to slag discharge, and the grate is also easy to be burned, so bagasse is used as a fuel in the boiler industry and encounters difficulties

Abstract

The invention relates to a bagasse-fired boiler which can ensure the smooth operation of the boiler, save resources, improve the utilization rate of the resources and protect the environment. The technical scheme is as follows: the bagasse-fired boiler comprises a furnace chamber, a feeding device, a grate, boiler drums, a tail flue, a superheater chamber, a soot blower and a boiler steel frame, wherein the grate is arranged at the lower part of the furnace chamber, the feeding device is arranged at the front part of the furnace chamber, the furnace chamber, the superheater chamber, the boiler drums and the tail flue are sequentially communicated, and the bagasse-fired boiler is characterized in that the grate is a water-cooled fixed grate specifically, the boiler drums are double boiler drums specifically, the double boiler drums are communicated through a convection bank, and the feeding device is arranged on the upper inclined side of the water-cooled fixed grate.

Description

technical field [0001] The invention relates to the field of boiler equipment, in particular to a bagasse boiler. Background technique [0002] In self-provided thermal power plants and industrial production, it is necessary to use the steam generated by the boiler. The fuel usually used by the boiler is fossil fuel, such as coal, oil and natural gas. Fossil fuel is a non-renewable primary energy. Due to the increasingly tight supply of primary energy and the rising price, it has become a major problem that seriously restricts the sustainable development of the national economy. [0003] In order to deal with the shortage of primary energy, to develop the economy and improve people's lives, there is more demand for energy, in addition to strengthening energy conservation and reducing consumption and improving the utilization rate of primary energy, we should also actively strive to seek new energy, which has become a national standard. The only way for the development of en...
