Description
Technical field
The present invention relates to a kind of novel dual-purpose boiling type hot-blast stove of bottle coal, especially suitable coal, blast furnace gas be applied alone, uses with
Hot-blast stove.
Background technology
Fluidized bed furnace is a kind of coal furnace developed in recent years, it, which can not only burn, burns fat coal, can also burn general stove
All kinds of colms that grate furnace and room burner cannot be burnt, and combustion efficiency is good, the thermal efficiency is high.
But environmental requirement now, burned coal price increasingly improve, and many enterprises start to try every possible means to fire using other energy substitutions
Coal.Blast furnace gas combustible component is low, combustion instability, ignition temperature is low, exhaust gas volumn is big, is not paid attention in the past by everybody, now because of drop
Cost needs are gradually used, wherein more is that pervious fluidized bed furnace is changed to the dual-purpose fluidized bed furnace of gas, coal, can burn gas
It is cost-effective also to burn coal to solve the problems, such as that unstable, the newly-built gas burner of blast furnace gas is of high cost, security risk is big.
When because of a kind of blast furnace gas is low heat value, impurity content is high, unstable for feed, toxicity is big its burning of fuel
Need the air before paying close attention to fire box temperature and burning and coal gas mixed proportion.Conversion between gas, coal needs strictly handle
The amount held opportunity and substituted mutually, once holding inaccuracy easily causes convert failed even coking.It is guided using coal gas
Stove is difficult the coal amount for holding coal opportunity and each time when burning coal.When bottle coal is used with, air blast is wanted because burning coal and burning gas
It asks and differs greatly, artificial control is difficult the control equalization point, often causes coal coking or burning insufficient, on the other hand in people
Substantially it can only ensure that the normal of burner hearth is difficult to take into account cost control problem, traditional coal, gas dual-purpose fluidized bed furnace when industry control
The labor intensity of stoker personnel has been aggravated significantly.Simultaneously because coal-fired burning point is high, furnace igniting difficulty is opened, a large amount of combustibles need to be consumed
Igniting；Existing fluidized bed furnace is due to the defect in structure, and making it, heat flow is slow in use, and boiling dross coal is easy close-burning,
Blowing out scarfing cinder is needed once stopping burning after coking is serious, directly affects the continuous operation of production.Existing single coal-fired fluidized bed furnace pair stove
Thorax tubular type air blast, easily causing air hose air port and blocking makes secondary-furnace disabler.
Invention content
The purpose of the present invention is in view of the above problems, a kind of novel dual-purpose boiling type hot-blast stove of bottle coal of offer, gives full play to
Single coal-fired boiling type hot-blast stove is adapted to the dual-purpose boiling type hot-blast stove of bottle coal, led to by the advantages of coal-fired boiling type hot-blast stove
It crosses single or is used in mixed way, make full use of blast furnace gas more than needed, reduce coal-fired cost；Single coal-fired fluidized bed furnace is overcome to open furnace igniting
Difficult, easy close-burning, Single gas hot-blast stove gas supply unstable the problems such as causing hot wind unstable.
In order to achieve the above object, the technical solution adopted by the present invention is：
