A central air pipe is outwardly and coaxially fixed with a gas pipe, a rotational flow air pipe and an axial flow air pipe in turn; a gas channel is formed between the central air pipe and the gas pipe; a rotational flow air channel is formed between the gas pipe and the rotational flow air pipe; an axial flow air channel is formed between the rotational flow air pipe and the axial flow air pipe; the outer wall of the axial flow air pipe stretching into a rotary kiln part is provided with a fireproof protective layer; a gas rotational flow nozzle ring is fixed between the central air pipe at the end of the axial flow air pipe stretching into the rotary kiln part and the gas pipe; a rotational flow air nozzle ring is fixed between the gas pipe and the rotational flow air pipe; and an axial flow air nozzle ring is fixed between the rotational flow air pipe and the axial flow air pipe. The gas burner can directly burn low-heat value gas produced by a gas producer.
Description
Technical field
The present invention relates to a kind of gas burner, particularly a kind of gas burner of active lime rotary kiln producer.
Background technology
The operable fuel of active lime rotary kiln production technology has natural gas, high heating value gas, heavy oil and coal.Make the active lime rotary kiln production line of fuel with coal gas, flexible operation, convenience, clean, small investment, but source of the gas is restricted---when using coal gas, coke-stove gas or calorific value blast furnace, the coke oven mixed gas more than 1254MJ/m3 (3000kcal/m3) preferably, if calorific value is too low, enough heat supply intensity is arranged in the time of can not guaranteeing roasting, can influence lime quality.
The producer gas main component is carbon monoxide, hydrogen, nitrogen, carbon dioxide, and comhustible component is carbon monoxide and hydrogen, and wherein carbon monoxide content reaches about 38.5%, and it is upright that hydrogen content about 40%, calorific value are about 11000 kilojoule/marks.Owing to contain a large amount of inertia component nitrogen, so calorific value of gas is not high, is a kind of low-calorie gaseous fuel.So be not suitable for doing the gaseous fuel of active lime rotary kiln producer.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of gas burner of active lime rotary kiln producer, it is the low-heat value gas of coal combustion gas producer production directly.
The present invention solves the technical scheme that its technical problem takes: the outwards coaxial successively fixedly gas pipe of central air hose; eddy flow airduct and axial flow airduct; form gas passage between central air hose and the gas pipe; form eddy flow wind passage between gas pipe and the eddy flow airduct; form axial flow wind passage between eddy flow airduct and the axial flow airduct; stretch on the rotary kiln axial flow airduct outer wall partly refractory protection is arranged; stretch between the central air hose of axial flow airduct end of rotary kiln part and the gas pipe fixedly coal gas eddy flow spout ring; fixing eddy flow wind snout ring between gas pipe and the eddy flow airduct, fixing axial flow wind snout ring between eddy flow airduct and the axial flow airduct.
The present invention has following advantage: 1, the employing brute force is penetrated the suction principle and is drifted along or through outward and close mode, promptly according to fluid mechanics principle, utilizes the suction effect of penetrating of high-voltage high-speed air draught, strengthens the conveying and the injection of producer gas.2, be the combustion technology that adopts high speed difference and strong eddy flow theory.3, air is mixing after the burner ejection with coal gas, utilize tangential air-supply and the steady flame of vortex, make the producer gas jet of low pressure in long mixed flow, be uniformly mixed, strengthened coal gas and Air mixing, improved combustion intensity, made the burner compact conformation.4, directly use the low-pressure gas of gas generator production to go into the kiln burning, coal gas need not to carry out washing, purifying and pressurization.5, axial flow wind, eddy flow wind and center wind duct are equipped with butterfly valve respectively, are used to regulate the air quantity of respective channel, convenient flame profile and the length adjusted.
