Problems solved by technology
However, the feeding equipment in front of the biomass boiler furnace cannot solve the problem that the granular biomass fuel is unevenly distributed after being fed, and it is easy to accumulate at one point, resulting in insufficient combustion and black smoke, and it uses sensors, etc. Electronic components have many components and complex overall structure, so machine failures are prone to cause downtime losses

Embodiment Construction
[0020] see figure 1 and figure 2 , the boiler feeding system of the present embodiment is mainly applied to heat conduction oil furnaces and steam boilers burning biomass briquette fuel (i.e. bio-mass fuels, referred to as BMF). 1. The feed port of the boiler 2 is connected to the connected distributing device 3, and a blanking device 4 perpendicular to the horizontal plane is connected between the discharge port of the feeder 1 and the distributing device 3, and the upper part of the blanking device 4 passes through a The flange 5 is connected with the feeder 1 , and the granular biomass briquette enters the distribution device 3 through the discharge channel 6 of the discharge device 4 . The distributing device is an isosceles trapezoidal distributing tube, and the upper and lower side plates and the left and right side plates of the distributing tube form a distributing channel 7 that is also in the shape of an isosceles trapezoid. The opening forms the narrow end 8 of t...

The invention discloses a boiler feeding system. The system comprises a feeding machine and a splitting device, wherein a gradually widened-type splitting channel is formed in the splitting device, a narrow end of the splitting channel is communicated with the feeding machine and a wide end of the splitting channel is communicated with a feed inlet of a boiler; and a plurality of stream separating bodies for splitting a fuel are arranged from the narrow end to the wide end in the splitting channel. The splitting device is provided with the gradually widened-type splitting channel, the fuel isdifficult to block when entering the boiler under the condition of unchanged size of a discharge outlet of the feeding machine, and the area range of the fuel dropping into the boiler is widened to ensure that the fuel is scattered and burned fully.
Description
technical field [0001] The invention relates to a material feeding system for boiler equipment, more specifically, the invention relates to a material feeding and distributing device for biomass briquette fuel and a boiler system using the feeding and distributing device. Background technique [0002] At present, industrial boilers are mainly fueled by oil, natural gas and coal. With the continuous rise of oil and natural gas prices, many companies have been unable to bear such a high fuel cost; although the cost of burning coal is relatively low, the pollution to the environment due to the nitrogen oxides and sulfides in its combustion products has become more and more serious. The more serious, the national policy has strictly restricted the use of coal fuel. Biomass fuel is a typical circular economy project because of its low sulfur content, low nitrogen content and low pollutant content in flue gas generated during combustion, and it comes from agricultural and forestr...
