Problems solved by technology

[0002] At present, there are many known vertical boilers using solid fuels, which generally cannot use water as an oxidant, and do not have the function of multi-water jacket series heating. Very good treatment, fuel combustion is not sufficient, soot can not be effectively treated, not only waste of energy, but also pollute the environment

Embodiment Construction

[0042] figure 1 It is a structural schematic diagram of the first embodiment of the present invention. Open push-pull ash door 6, light a fire, its method is identical with general vertical boiler.

[0043] After igniting the fire, fill up the fuel once, and close the push-pull ash door 6.

[0044] According to the use requirements of large fire and small fire, adjust the one-way valves of the lower tuyere 8, the middle tuyere 13, the upper tuyere 15, the ash removal furnace door 9 and the feeding furnace door 14 respectively, and adjust the mist according to the water content of the fuel. Reduce the amount of dripping water, so that the combustion in the furnace is in a normal smokeless combustion state. The fuel starts to dry and dehydrate from top to bottom, volatile matter is precipitated, fixed carbon is formed, tar is cracked, water is heated up to high-temperature steam as an oxidant, and a thermochemical reaction occurs with carbon or hydrocarbons to produce hydrogen...

Abstract

The invention relates to an energy-saving emission-reducing vertical fire-tube boiler capable of using water as oxidant. A plurality of water jackets (water containers) are serially connected, a vertical fire tube heating mode is adopted, the water can be used as the oxidant, combustion efficiency is high, the quantity of consumed oxygen is low, accordingly, a heat exchange effect is improved, heat efficiency is enhanced, and energy is saved. A combustion principle of the energy-saving emission-reducing vertical fire-tube boiler includes that hydrogen and carbon are used as energy carriers, and energy can be exchanged between hydrogen and carbon. The carbon or hydrocarbon and water realize 'oxygen deprivation' reaction in a high-temperature environment, namely high-temperature steam is used as the oxidant to realize thermal chemical reaction with the carbon or the hydrocarbon, and hydrogen-rich gas is generated. Energy is absorbed during hydrolysis while energy is released during oxidation of the carbon, and energy is exchanged between the carbon and the hydrogen. The high-temperature environment is required when the energy is exchanged between the carbon and the hydrogen, and the energy is only consumed to maintain the high-temperature environment required by the thermal chemical reaction. Accordingly, by the aid of the energy-saving emission-reducing vertical fire-tube boiler, smokeless combustion of coal can be realized, and biomass fuel containing a large amount of water, domestic garbage and industrial and agricultural combustible waste are suitable to be used as energy sources.

Description

technical field [0001] The invention relates to an energy-saving and emission-reducing vertical fire-tube boiler capable of using water as an oxidant, which can not only realize coal smokeless combustion, but also be suitable for using biomass fuel with high water content, domestic garbage and combustible industrial and agricultural waste as energy. Background technique [0002] At present, there are many known vertical boilers using solid fuels, which generally cannot use water as an oxidant, and do not have the function of multi-water jacket series heating. If the treatment is good, the fuel is not fully burned, and the smoke and dust cannot be effectively treated, which not only wastes energy, but also pollutes the environment. Contents of the invention [0003] The purpose of the present invention is to provide an energy-saving and emission-reducing vertical fire-tube boiler that can use water as an oxidant. It adopts multiple water jackets (water containers) connected...
