Abstract

The utility model discloses an ignition device for a biomass burning furnace, which is arranged under a combustion chamber of a furnace body and comprises a hearth and an air blowing pipeline. A flame bridge is located at the position of an ignition opening of the combustion chamber of the furnace body above the hearth, the air blowing pipeline is arranged under the flame bridge, and the air outlet faces the flame bridge. Three heating pipes are arranged in the flame bridge and are electrically connected with electrodes of a power source for heating, and then biomass fuels in the combustion chamber of the furnace body are ignited. A flame bridge assembly comprises the flame bridge, a flame bridge support, a flame bridge limit plate and a flame bridge ash hopper, wherein the flame bridge is installed on the flame bridge support, the flame bridge limit plate is arranged on one side of the flame bridge, and the flame bridge ash hopper is used for containing fuel ash dropping from the flame bridge. By means of an electrical heating ignition mode and the heating pipes arranged in the flame bridge for the heating, a control system automatically cuts off the power source of the heating pipes after heating for three minutes, and automatic ignition can be achieved when the temperature is higher than an ignition point of biomass in the furnace body. Compared with a gas combustion ignition mode, the ignition device for the biomass burning furnace greatly improves safety performance.

Description

Biomass combustion furnace igniting device

Technical field

The utility model discloses a kind of biomass combustion furnace igniting device, divides by International Patent Classification (IPC) (IPC) to belong to combustion furnace class manufacturing technology field, especially relates to the combustion furnace ignition device of a kind of biomass energy as fuel.

Background technology

The biomass combustion stove; Be with the alternative energy source emerging fuel boiler of living beings as traditional fuel (like coal etc.); Having energy-saving and environmental protection and fuel is advantages such as renewable resource; Therefore promoting various power-saving technologies, improve especially biomass combustion stove of Industrial Boiler, is the direction that energy industry person keeps punching.

Traditional combustion apparatus is used igniter, generally adopts manual work to control, and the IGNITION CONTROL time is difficult for grasping.Applied for a kind of employing gas firing igniter before the applicant, though solved manual firing's drawback, because there is certain potential safety hazard in the gas firing igniting, severe patient causes boiler explosion accident.

Summary of the invention

To the deficiency of prior art, the utility model provides a kind of rational in infrastructure, safe and reliable biomass combustion furnace igniting device, and this device adopts the electrical heating sparking mode, and security performance improves greatly.

For achieving the above object, the utility model is realized through following technical scheme:

A kind of biomass combustion furnace igniting device; Be arranged at combustion chamber of furnace body below; This device comprises burner hearth and blowing pipeline, and the lighting-up tuyere place of burner hearth top combustion chamber of furnace body is provided with the grate assembly, the blowing pipeline be arranged at below the grate assembly and its air outlet facing to the grate of grate assembly; Described grate heating pipe built-in, heating tube and power electrode electrically connect heating and biomass fuel in the combustion chamber of furnace body of igniting.

Further; Described grate assembly comprises that grate, grate support, grate limiting plate and grate ash bucket, grate are installed on the grate support and in grate one side the grate limiting plate is set; The combustion ash that the grate ash bucket is used for falling on the ccontaining grate, built-in three heating tubes of described grate.

The utility model is because grate adopts the electrical heating sparking mode, ignites automatically when the grate temperature is higher than the burning-point of body of heater endogenous substance, compares with the gas firing sparking mode, and security performance improves greatly.The utility model uses the wood pellet biomass fuel, and efficiency of combustion is high, can reach more than 90%, and be fuel owing to adopt the renewable biomass energy, fractional energy savings has been realized the sustainable and efficient utilization of the energy up to more than 60%, and the NO in the flue gas _X, SO ₂, discharging such as dust is low, environmental benefit is obvious.
