For a long time, steam boiler, hot-blast stove are the maximum users of China's primary energy, almost annual 1/3rd of the national raw coal output that consumes.And steam boiler, hot-blast stove use widely in industries such as food, medicinal material, weaving, papermaking, chemical industry, metallurgy, building materials.These industries, in the time of needs steam, start steam boiler; In the time of needs hot blast, start hot-blast stove, these two kinds of type of furnaces are changed mutually, and fortune fortune is stopped, and causes the cyclically-varying of imbalance and the combustion process of supply and demand.This just causes the operating thermal efficiency of steam boiler, hot-blast stove not high, and particularly heat loss of imperfect solid combustion increases, and energy loss waste is quite serious.China's " 12 " development plan continues to classify energy-saving and emission-reduction as restrictive performance assessment criteria, solve as early as possible steam boiler, the high heat loss of hot-blast stove, improve steam boiler, hot-blast stove efficiency of fire coal, save valuable coal-fired resource, realizing the energy-saving and cost-reducing of steam hot wind all-in-one oven, is the vital task that China's steam boiler and hot-blast stove industry are imminent.
Summary of the invention
The purpose of this utility model is that a kind of hot blast, steam one boiler will be provided.Hot blast, steam all-in-one oven are provided with two completely independently hot exhaust gases passes, and hot blast, steam are arbitrarily adjusted according to demand by two air-introduced machines, jointly enter wind mixed chamber, send into dryer by air-heater.
The utility model is achieved in that a kind of hot blast, steam one boiler, is made up of upper coal bunker 1, burner hearth 3, smoke outlet window 5, combustion chamber 7 and flue 18; It is characterized in that burner hearth 3 front ends have upper coal bunker 1 with height and short face arch 2, after burner hearth 3, there is the chevron shaped rear arch 4 compared with Gao Erchang, chevron shaped rear arch 4 longitudinal sections be shaped as " people " character form structure, after chevron shaped rear arch 4, have smoke outlet window 5, burner hearth 3 is vertically separated into combustion chamber 7 and cooling chamber; Left side air inlet duct 23 and right side air inlet duct 32, be positioned at airtight isobaric air compartment 9 both sides, and airtight isobaric air compartment 9 is made up of dnockout core fire grate 6, wind isolation board 8, base plate 10; On water pipe 16, connect drum 20, under connect lower drum 22, water pipe 16 is positioned at flue 18, in water pipe 16 first three array of pipes, be equipped with separate plate washer 15; After exhaust gases passes 11, have upper flashboard 12 and exhanst gas outlet 13, exhaust gases passes has lower flashboard 14 11 times, and smoke evacuation outlet 19 is contained in the outside of stove; In boiler tube bundle region along arranging a soot blower 17 on boiler center line; Magnetic turnover panel 21 is contained in a side of upper drum 20.
On dnockout core fire grate 6, have fire grate segment shell 26, fire grate segment shell 26 has long and narrow socket 27 and groove straightthrough port 28.
In burner hearth 3, water pipe 16th district and have insulation material 25 between furnace wall 24.
Owing to having adopted technique scheme, by hot blast, steam one boiler conversion steam or hot blast, make full use of a large amount of hot flue gas that discharges in the process of producing steam and carry out the fertilizer that baking needed will be dried, dry the water vapour that the moisture content in fertilizer produces, contained sulphur nitre dust etc. in can the hot flue gas of washing discharge, fertilizer absorbs the materials such as sulphur nitre dust in washing simultaneously increases the element that fertilizer needs crops.Minus has lacked the furnace roof of this stove in the time producing hot blast and the heat loss of furnace wall, has more effectively utilized the energy, has reduced the waste of resource.
