Background technology
Traditional fuel oil, gas fired-boiler have multiple advantages such as operation is simple, soot emissions are less, the system equipment investment is low because of using clean energy resource.But traditional fuel oil, gas fired-boiler equipment combustion flame are cylindric streamlined flow backward after the burner ejection because the heating surface of burner hearth two side wall radiating furnace tubes is far away apart from column of flame edge, flame to the radianting capacity of radiating furnace tube a little less than; Because the flame streamlined flow, flow velocity is very fast, and flame is short in the burner hearth time of staying, causes the combustible burning insufficient, incomplete.Existence in view of the foregoing causes efficiency of combustion poor, and the thermal efficiency is on the low side, and exhaust gas temperature is higher, wastes energy, and sulfur dioxide and nitrogen oxide are higher, causes the atmosphere severe contamination.
The utility model content
At the deficiency of existing fuel oil, gas fired-boiler combustion technology, the purpose of this utility model is exactly to provide a kind of novel energy-saving and emission-reduction combustion technology to all kinds of fuel oils, gas fired-boiler equipment, changes burning situation with this.It can make the fuel-efficient burning, improves the fuel availability and the boiler operatiopn thermal efficiency, in the fuel-saving while, reduces pollutant emission, helps environmental protection.
Be the purpose that realizes that above-mentioned technical application is novel, the utility model by the following technical solutions:
A kind of energy-saving and emission-reduction fuel oil, gas fired-boiler equipment, this equipment body structure comprise the radiation chamber burner hearth, go up lower drum, radiating furnace tube and burner etc.
Described radiation chamber inside is the burner hearth of hollow.
Described radiation chamber both sides interior wall is equipped with anti-clinker box and radiating furnace tube, and described radiating furnace tube is provided with along radiation chamber side wall inwall, and radiation chamber boiler tube bottom is connected with anti-clinker box, and top is connected with upper drum.
Described radiation chamber front wall is equipped with burner, is the fuel flame jet.
The front portion is provided with the high-energy radiation cover in the described radiation chamber burner hearth, and the high-energy radiation cover can be different shape commonly used, and is preferred square or circular, and the high-energy radiation cover is connected with the radiation chamber bottom by bearing; Being covered with around the described high-energy radiation cover has the water conservancy diversion hole, and the water conservancy diversion pore quantity is selected according to actual conditions, is generally dozens of; The described hole general diameter is 20~40mm, and distance is 150~200mm between the adjacent holes.Described high-energy radiation cover is coaxial with burner.Described high-energy radiation cover is that multi-functional fire-resistant concrete or metal material are made.
Described high-energy radiation cover afterbody is provided with the flue gas shunting baffle plate, and described distributing damper is taper, and described angle of taper is 20 °~160 °, and preferred 60 °~120 °, most preferably 90 °.Described flue gas shunting baffle plate is coaxial with the high-energy radiation cover.Described flue gas shunting baffle plate is that multi-functional fire-resistant concrete or metal material are made.
The utility model technological merit is:
The utility model in all kinds of fuel oils, gas fired-boiler equipment burner hearth, add be covered with the high-energy radiation cover of hole after, the first combustion flame that sprays into from burner is in high-energy radiation cover internal combustion, the outer air communication of radiation shield is crossed cover cinclides hole and is inhaled in the cover, form the crossflow disturbance, changed the flame burning state, flame combustion state becomes turbulent flow by direct current, produce turbulence effect, fuel and air are more fully mixed, strengthened combustion conditions, promoted the after-flame of fuel.
2. the high-energy radiation cover has very strong heat accumulation function, and it accumulates into temperature waits high temperature up to 1300 ℃ combustion chamber with heat.According to Si Difen--the Boltzmann law: the biquadratic of radiant body radiations heat energy and radiant body self temperature is directly proportional, the high-energy radiation cover becomes powerful radiation source, the combustion chamber of a brand-new burning situation and " impartial high temperature " has been brought up in its internal radiation, and fuel more fully burnt; It changes into the infrared ray electric electromagnetic wave radiation to external radiation by original visible radiation, gives boiler tube by the infrared heat conduction with heat radiation.Strengthened the intensity of heat exchange of radiation chamber body, reached the positive effect of gas fired-boiler energy-saving and emission-reduction boiler tube.
3. the utility model is provided with a distributing damper at high-energy radiation cover afterbody, its effect: 1. increase the flow of flue gas resistance, the reducing smoke flow velocity has prolonged the time of staying of high-temperature flue gas in the high-energy radiation cover, makes full combustion of fuel; 2. taper flue gas shunting baffle plate has changed the flame movement direction, flame becomes high-energy radiation cover external curve by streamlined flow and flows in the high-energy radiation cover, thermal-flame has been strengthened the intensity of heat exchange of radiating furnace tube, at the fuel-saving thermal efficiency that improves boiler simultaneously more near radiating furnace tube.
