The invention relates to a pulverized coat burner for a hot blast furnace of a grain drying tower and belongs to pulverized coat burners. A primary air supply duct is connected with a pulverized coat sprayer through a flange. The pulverized coat sprayer is fixedly connected with an access door. The access door is connected with a burner body through hinges. A hand wheel, a threaded telescopic link, a guide impeller and a flow guider are connected together and installed in the pulverized coat sprayer. The burner body comprises a high-temperature refractory layer and a water cooling layer in sequence from inside to outside. A water pump is located in a water tank and connected with the water cooling layer through a water pipe. A secondary air supply duct is connected with the burner body. A wind deflector is fixedly connected into the burner body and located on the opening portion of the secondary air supply duct. A diesel oil ignition device is located outside an ignition hole. The pulverized coat burner for the hot blast furnace of the grain drying tower has the beneficial effects of being novel in structure, stable in work and easy to maintain; and the pulverized coat burner for the hot blast furnace of the grain drying tower further has the beneficial effects that pulverized coat stays in a high-temperature area of the burner for a long time, so that the combustion efficiency is high and reaches over 95%, combustion is complete, and the pulverized coat burner is high in efficiency and saves energy.
Description
technical field [0001] The invention belongs to a pulverized coal burner, in particular to a pulverized coal burner used in a grain drying tower hot air stove. Background technique [0002] The chain-type hot blast stove has been used in the grain drying tower for many years. The burn-out rate of the chain-type hot-blast stove is low, and the thermal efficiency is only about 70%. By changing its combustion method to a pulverized coal combustion method, the burnout rate of coal can be improved. It can reach about 98%, and the thermal efficiency is increased to about 95%. The existing pulverized coal combustion devices on the market are difficult to control the air volume, flame length and flow rate in the transformation of the grain drying hot blast stove to make it meet the drying requirements. Contents of the invention [0003] The invention provides a pulverized coal burner for a hot blast stove of a grain drying tower to solve the problem that the existing pulverized c...
