Biomass molding fuel combustion boiler

Abstract

The invention discloses a biomass molding fuel combustion boiler. The biomass molding fuel combustion boiler comprises a hearth, a water cooling wall layer and a heat insulation layer, wherein the water cooling wall layer covers the outer side of the hearth; the heat insulation layer covers the outer side of the water cooling wall layer; a feeding hole and a chimney are mounted at the top of the hearth; a charging door is mounted on the feeding hole; a crushing device is mounted in the feeding hole; a plurality of rotary shafts are arranged in the crushing device; each rotary shaft is provided with a rotary head; each rotary head is provided with a crushing blade; a mesh screen is mounted at the bottom of the crushing device; a vibration motor is mounted at the bottom of the mesh screen; a through hole is formed in the mesh screen; the hearth is provided with a gasification region and a combustion region; a water cooling wall layer is arranged between the gasification region and the combustion region; the combustion region is internally provided with a plurality of fire pipes; the water cooling wall layer is arranged between the adjacent two fire pipes; a fire grate is mounted under the gasification region and a rotary shaft is mounted on the fire grate. By the aid of the biomass molding fuel combustion boiler, the combustion temperature of fixed carbon is reduced, slag is not easily formed by ash and fireproof materials are arranged at the periphery of the combustion region, so that the temperature of the combustion region can be improved.

Description

【Technical field】 [0001] The invention relates to the technical field of boilers, in particular to the technical field of biomass briquette fuel combustion boilers. 【Background technique】 [0002] In today's world, human beings are facing multiple pressures such as economic growth, environmental protection and social development. Changing the way of energy production and consumption is of great significance to the establishment of a sustainable energy system, the promotion of economic and social development and the improvement of the ecological environment. Development Renewable energy has drawn wider attention. Among all renewable energy sources, biomass energy is regarded as one of the main choices due to its superior performance. The carrier of biomass energy is organic matter, which exists in the form of physical objects, and is the only renewable energy that can be stored and transported. At the same time, from a chemical point of view, the composition of biomass is a...

Problems solved by technology

Moreover, the content of alkali metals in straw ash is relatively high, and its reaction with silica forms a eutectic with a low melting point, which reduces the melting point of biomass ash and makes straw ash very easy to slagging

Foreign biomass briquette fuel application equipment is designed according to the characteristics of woody briquette fuel, which is not suitable for my country's straw briquette fuel, and the directly imported biomass briquette fuel boilers cannot be used normally in our country. Therefore, it is necessary to propose a suitable Domestic straw briquette fuel combustion boilers
