Problems solved by technology

[0003] At present, the situation of air pollution prevention and control is severe, and a large number of coal-fired boilers need to be replaced by clean energy for heating. Moreover, the biomass pellet boilers currently on the market have two problems: one is that the heat transfer per unit volume is poor, and the exhaust gas temperature Second, the existing biomass pellet boilers are incompletely combusted and will produce a large amount of dense smoke, which will have a certain impact on the environment; this invention mainly studies a biomass pellet boiler with high heat transfer performance and complete combustion

Abstract

The invention relates to a compact, small-capacity, and high-efficiency biomass pellet boiler, which includes an intelligent control system, a combustion chamber, a burner, a flue gas outlet, a primary fan, a secondary fan, an induced draft fan, a deaerator, a heat exchange chamber, and a cloth bag. Dust collector, steam-water separator, sub-cylinder, boiler water purifier; the heat exchange chamber adopts convection tube bundle heat exchange, and the heat exchange chamber is divided into four areas from top to bottom, and all four areas are equipped with blowing devices. The deaerator can not only reduce the insulation thickness but also preheat the water while ensuring the combustion temperature in the furnace; the combustion chamber and the heat exchange chamber are arranged separately; the combustion chamber adopts the reentrant arrangement and the type of secondary air to ensure complete combustion; heat exchange The room is divided into multiple areas to ensure complete heat exchange on the basis of clean pipes, and the exhaust gas temperature is low; bag dust removal ensures that the flue gas flowing to the atmosphere is fully clean; compact layout ensures the smallest volume of the whole machine.

Description

technical field [0001] The invention relates to biomass energy equipment, in particular to a compact, small-capacity, and high-output biomass particle boiler. [0002] technical background [0003] At present, the situation of air pollution prevention and control is severe, and a large number of coal-fired boilers need to be replaced by clean energy for heating. Moreover, the biomass pellet boilers currently on the market have two problems: one is that the heat transfer per unit volume is poor, and the exhaust gas temperature Second, the existing biomass pellet boilers are incompletely combusted and will produce a large amount of dense smoke, which will have a certain impact on the environment; this invention mainly studies a biomass pellet boiler with high heat transfer performance and complete combustion. Contents of the invention [0004] The purpose of the present invention is to provide a compact, small-capacity and high-output biomass pellet boiler with high heat exch...
