Biomass and clean coal series-burning fire bed vertical boiler

Abstract

The invention discloses a biomass and clean coal series-burning fire bed vertical boiler. The biomass and clean series-burning fire bed vertical boiler comprises an outer cylinder, an inner container, a firewood chamber, a coal chamber and an incineration chamber. The inner container is mounted in the outer cylinder. The inner container is divided into the firewood chamber, the coal chamber and the incineration chamber. The firewood chamber and the coal chamber are partitioned through water pipe partition walls. Gap holes are reserved among the water pipe partition walls. The coal chamber is partitioned from the incineration chamber through a fin type water pipe fire wall. A mixed smoke outlet is reserved in the lower portion of the coal chamber. The boiler is simple in structure and reasonable in design, a new burning manner of firewood and coal series-burning is achieved, natural induced air is adopted for the boiler, no induced draft fan is needed, and the electricity is saved. Biomass and combustible garbage are adopted as fuels for the boiler, burning is more thorough, zero-pollution is achieved, energy saving and environment protection are achieved, and the biomass and clean coal series-burning fire bed vertical boiler provides a new burning technical manner and is suitable for being applied and popularized.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a vertical boiler fired with biomass and clean coal. Background technique [0002] At present, the biomass fuel burned by industrial boilers and hot water heating boilers is high-pressure, and the crop straws bonded with adhesives are in the shape of lumps or granules. Due to the high manufacturing cost and high price, users cannot accept it. Scattered coal is still used, and it has been proven that scattered coal is an important factor in the generation of smog. Therefore, in the future, scattered coal will no longer be used as the main raw material for industrial boilers and hot water boilers, and gas and electric heating will be used as the main raw materials for industrial boilers and hot water heating boilers. Fuel costs are still high. In the future, the cheapest boiler fuel will be clean coal, straw, and domestic waste. Boilers can directly burn straw and domestic waste w...

Problems solved by technology

[0002] At present, the biomass fuel burned by industrial boilers and hot water heating boilers is high-pressure, and the crop straws bonded with adhesives are in the shape of lumps or granules. Due to the high manufacturing cost and high price, users cannot accept it. Scattered coal is still used, and it has been proven that scattered coal is an important factor in the generation of smog. Therefore, in the future, scattered coal will no longer be used as the main raw material for industrial boilers and hot water boilers, and gas and electric heating will be used as the main raw materials for industrial boilers and hot water heating boilers. Fuel, still expensive

In the future, the cheapest boiler fuel will be clean coal, straw, and domestic waste. Boilers can directly burn straw and domestic waste without processing. Farmers can exchange firewood for money, and there will be no phenomenon of burning straw in the field. The direct combustion technology of straw and domestic waste is not yet perfect, let alone combusted with clean coal
