Description
Technical field
The present invention relates to a kind of biomass boiler monitoring system.
Background technology
Hot-water boiler is that a kind of fuel that utilizes commonly used discharges chemical energy in the stove internal combustion, water at low temperature is heated to the thermal power transfer equipment of the high-temperature water of uniform temperature.Hot-water boiler is widely used in the fields such as hot water, heating of producing of industrial and agricultural production and daily life.The source that present hot-water boiler generally adopts coal, oil, electric energy etc. to act as a fuel.
Hot-blast stove is to utilize fuel (coal, oil, natural gas and organic waste etc.) to discharge chemical energy in the stove internal combustion, Cryogenic air is heated to the thermal power transfer equipment of the high temperature air of uniform temperature.Hot-blast stove also can utilize other heat energy (electric energy, waste heat) to add hot-air.Hot-blast stove is widely used in heat supply and dry fields such as plastics, rubber, chemical industry, application, weaving, printing and dyeing, non-weaving cloth, papermaking, insulation material, pharmacy, medicinal material, agricultural product, feed, food, casting, building materials, timber, pottery, welding material.Hot-blast stove also is applicable to places such as large space, the heating of intermittent heat supply place, the deicing of mine well head, agricultural kind aquaculture.
Biomass fuel is meant that organic agronomic crop, solid waste such as adopting rice husk, stalk, bagasse, wood chip, wood chip, sawdust, bamboo bits, bamboo silk, animal wastes are raw material, through pulverizing a kind of fuel of back pressurization, density moulding, it has bulk, multiple shape such as spherical, bar-shaped, its have volume little, than great, anti-burning, be convenient to store and advantages such as transportation.Fugitive constituent accounts for the overwhelming majority in the biomass fuel, and it can produce imflammable gas such as a large amount of methane when heating, and the imflammable gas burning can produce a large amount of heat energy.As with the fuel of biomass fuel, then can bring than existing fire coal and the better advantage of oil burning boiler as hot-water boiler.Equally, adopt the hot-blast stove of biomass fuel to have advantages such as low pollution, heat energy height, efficiency of heating surface height, solid slag are few, long-life.
But because the boiler structure of fuel such as the structure that adopts the hot-water boiler of biomass fuel or hot-blast stove and employing coal is similar, so biomass boiler also can adopt coal to act as a fuel.Reduce the consideration of polluting for the environmental protection aspect, a lot of at present local uses that all limited coal-burning boiler, even ban use of.Though it is few that biomass boiler pollutes with respect to coal-burning boiler, but because the interchangeability of fuel, in order to prevent to use the biomass boiler burning coal, some are local even also biomass boiler has been carried out restriction or ban use of, and give popularizing and using and brought bigger difficulty of biomass boiler.If can guarantee that biomass boiler only uses biomass fuel avoid the burning coal of high pollution, then can get around the restriction of above-mentioned policy, for the gate is opened in the use of biomass boiler by technological means.
In addition, prior biological matter fuel heat homogeneous solution-type reactor or hot-blast stove all need to open fire door when each feeding, after the oven door opening, unnecessary natural air is entered in the burner hearth, thereby reduced efficiency of combustion.And when each feeding, it is used for the reciprocal manually pusher of expeller needs of pusher, and labor intensity of operating personnel is big, makes production efficiency low.
Summary of the invention
