Lignose fuel boiler

Abstract

The invention provides a boiler using login as the fuel. The lignin is used as the main fuels, thus saving a large quantity of non-renewable mineral fuels and saving energies, at the same time, reducing the problem of environment pollution caused by the discard of the lignin, effectively solving the problem of material spilling of the login in the burning process and improving the burning efficiency of the boiler. The boiler using login as the fuel comprises a furnace hearth, a boiler drum, a steel frame, an inversion chain grate, a reburning chamber, a superheated chamber and a smoke channel in the tail part, wherein the furnace hearth is arranged on the steel frame; above the furnace hearth, the boiler drum is arranged and the inversion chain grate is arranged in the lower part of the furnace hearth; behind the furnace hearth, the reburning chamber, the superheated chamber and the smoke channel in the tail part are sequentially arranged. The boiler using login as the fuel is characterized by also comprising a lignin burner and a lignin spray seeding device, wherein the lignin burner is arranged on the side wall in the lower part of the furnace hearth and the lignin spray seeding device is arranged on the front wall of the lower part of the furnace hearth.

Description

(1) Technical field [0001] The invention relates to the field of boiler equipment, in particular to a lignin fuel boiler. (2) Background technology [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 coal, oil, natural gas and other fossil fuels. Mineral fuels are non-renewable primary energy sources, and their prices continue to rise, resulting in production costs. keep growing. Lignin is a waste of papermaking, and it is also a valuable energy source. If it is discarded as industrial waste, it will not only waste resources, but also pollute the environment. Using lignin to incinerate in a boiler, the steam generated is used for power generation and steam supply, which has the potential to save energy. , the social benefits of reducing environmental pollution, and also good economic benefits, but due to the small size of lignin particles, when it is direct...

AI Technical Summary

Problems solved by technology

[0002] In the self-provided thermal power plant and industrial production, it is necessary to use the steam generated by the boiler. The fuel usually used by the boiler is coal, oil and natural gas and other fossil fuels, and the fossil fuel is The price of non-renewable primary energy is constantly rising, resulting in increasing production costs

Lignin is a waste of paper production, and it is also a valuable energy source. If it is discarded as industrial waste, it will not only waste resources, but also pollute the environment. Using lignin to incinerate in a boiler, the steam generated is used for power generation and steam supply, which has the potential to save energy. , The social benefits of reducing environmental pollution also have good economic benefits, but due to the small size of lignin particles, when it is directly used as fuel in ordinary coal-fired boilers, the phenomenon of material leakage is serious, and the loss of mechanical incomplete combustion is large. Low combustion efficiency
