Abstract
A dual-phase fuel combustion furnace mainly comprises a main combustion chamber (4). The difference of the dual-phase fuel combustion furnace is that the main combustion chamber (4) is connected to one end of a liquid fuel chamber (3), and the other end of the liquid fuel chamber (3) is connected to an air chamber (1), therefore, complete combustion of the fuel is achieved and instable combustion, blowing off the fire, extinguishing, emitting black smoke due of insufficient combustion and the like are avoided. The dual-phase fuel combustion furnace can be used for changing the fuel type and reducing the combustion cost, and is especially suitable for the operation of combustion furnaces in carbon black industry at lower temperature.
Description
Technical field:
The utility model relates to equipment, particularly a kind of employing gaseous state and the liquid fuel burnt fuel stove that a kind of boiler, combustion furnace, incinerator, black reactor etc. adopt the fuel combustion field.
Background technology:
A kind of oil gas two-phase fuel-fired furnace is a very important equipment in the carbon black subtractive process; At present; Along with day being becoming tight of international energy situation, low-carbon (LC) in the world wide, environmental protection pressure are increasing, and highly energy-consuming equipment such as boiler, combustion furnace, incinerator more and more are necessary to adopt cheap liquid hydrocarbon to act as a fuel; The liquid fuel that these prices are lower is because big, the difficult atomizing of oneself viscosity is difficult to separately fully burning; Also there is not a kind of equipment to can be good at overcoming the above problems now.
Summary of the invention:
The purpose of the utility model is exactly that a kind of combustion furnace that uses gaseous state and liquid fuel to burn simultaneously will be provided; The high viscosity liquid fuel that is difficult to independent burning the companion through the fuel gas that is easy to burn in burner hearth burn; Thereby can completing combustion, avoid combustion instability, the situation such as insufficient, over-emitting black exhaust of taking off fire, extinguish and burn; Be particularly suitable for when furnace temperature is low, using; Thereby reach the purpose of widening the fuel scope of application, can be used for changing fuel band, reduce burning fee and use.
The purpose of the utility model is achieved in that a kind of two-phase fuel-fired furnace, is made up of main chamber, it is characterized in that described main chamber connects an end in liquid fuel chamber, and the other end in liquid fuel chamber connects air chamber.
The described liquid fuel chamber of the utility model connects a gas spray gun with axial manner, and the center connects at least 2 liquid spray guns with radial manner.
The utility model compared with prior art has the following advantages:
Because adopted main chamber to connect an end in liquid fuel chamber, the other end in liquid fuel chamber connects the version of air chamber, thereby; Gaseous state, liquid two kinds of different fuel burn simultaneously, can carry out sufficient The pre-heat treatment to the liquid fuel that is difficult to burn; The higher calorific value gas that fuel gas generally adopts natural gas, coal gas, biogas, coke-stove gas etc. to be easy to burn both can use the simple substance fuel gas of single component, also can adopt the mist of multiple composition; Liquid fuel can adopt big, the difficult atomizing of viscosity, nonflammable oil system, the heavy liquid hydrocarbon of coal tar system, and fuel gas can not carry out preheating, and liquid fuel can carry out the height preheating to reduce viscosity; The characteristics of utilizing fuel gas to be easy to burn axially spray into fuel gas and burn in air draught, after the generation combustion gas that temperature is higher, oxygen is superfluous; Radially, multiple spot sprays into heavy oil; Make full use of the kinetic energy and the temperature of high temperature combustion residual air, heavy fuel is fully gasified, burning; Liquid fuel spray into Kong Keshe more than 2; With respectively spray into a little all with symmetry, fuel does not disturb mutually is principle; Spray into a little and on the burner hearth circumference, evenly distribute; The heavy liquid fuel can also be taked the form of carrier materialization except that carrying out the height preheating, is that the atomizing that carrier is further strengthened the heavy liquid fuel disperses with steam, compressed air.
It also is to reduce the heat loss of combustion furnace, except that being that heavy fuel provides the stable burning things which may cause a fire disaster through the auxiliary combustion of fuel gas, has also made full use of the kinetic energy of air with combustion residual air; The heavy fuel multiple spot sprays into the combustion residual air of high flow rate; It is more abundant to burn, and has the shorter length of flame thereby reach, main chamber can volume still less; Heat load intensity is higher, and the heat loss of equipment is also just littler.

1, air chamber 2, gas spray gun 3, liquid fuel chamber 4, main chamber 5, liquid spray gun
The specific embodiment:
Air chamber 1 is connected with an end in liquid fuel chamber 3, and liquid fuel chamber 3 other ends are connected with main chamber 4, and liquid fuel chamber 3 connects a gas spray gun 2 with axial manner, and the center connects 6 liquid spray guns 5 with radial manner.
During use, air can carry out preheating as having ready conditions, and injects through air chamber 1; Fuel gas can carry out appropriate preheating according to its ignition point, injects in the liquid fuel chamber 3 through gas spray gun 2, and liquid fuel can carry out the height preheating according to its initial boiling point; Be injected in the liquid fuel chamber 3 through liquid spray gun 5, carry out main chamber 4 internal combustion then, fuel gas is as auxiliary fuel; Liquid fuel is a main fuel; The characteristics of utilizing the fuel gas easy firing to be difficult for extinguishing, with a spot of fuel gas be viscosity big, be difficult for atomizing, nonflammable heavy liquid fuel provides stable burning things which may cause a fire disaster, occurs situation such as combustion instability, flame-out, over-emitting black exhaust during lower or normal combustion in fire box temperature to avoid liquid fuel; Can use the liquid fuel of heavy in a large number and guarantee its efficiency of combustion, thereby reach the purpose that reduces the burning cost.
