Detailed Description
In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail.
The utility model discloses a furnace body 1, steam package 3, water pump 4, diesel tank 8, switch board 5 and generating set 6, 1 inside two cavities of cutting apart into through the baffle of furnace body, one of them cavity is water tank 10, and another cavity is preheating chamber 11 in towering and being provided with combustion chamber 16 and flue 15, the two bottom intercommunication is provided with heating coil 17 in the combustion chamber 16, the 16 tops of combustion chamber are provided with the combustor. The above is a common structure in the prior art, and is not described herein again.
The most main innovation points of the invention are as follows: the combustor is a dual-purpose combustor for oil and gas, the combustor selected in the embodiment is ZOB series produced by Nanyang Zhongtong thermal energy equipment Limited, the novel dual-purpose boiler car for oil and gas further comprises a gas tank 9 for storing natural gas, the natural gas in the gas tank 9 is sent to the combustor, is sprayed out from the combustor and is mixed with air in a combustion chamber 16 for combustion; because natural gas is gas, atomization is not needed, and the situation of wax deposition does not exist in winter, the influence of weather on the use of natural gas is small, and the natural gas is used as combustion fuel, so that the cleanness and the environmental protection performance of the natural gas are all the best. However, natural gas also has the disadvantage that the calorific value of natural gas is low, and when rapid heating or a large amount of steam is needed, the natural gas obviously cannot meet the cleaning requirement, and at the moment, the natural gas needs to be switched to an oil-fired boiler.
A heat tracing coil 18 for heating the diesel tank 8 is arranged on the outer side of the diesel tank 8, one end of the heat tracing coil 18 is communicated with the preheating chamber 11, the other end of the heat tracing coil 18 is connected with an inlet of the water pump 4, and an outlet of the water pump 4 is communicated with the heating coil 17; therefore, the diesel oil tank 8 can be subjected to heat tracing in the process of pumping the preheated water, wax is melted, and the structural design is simple and reasonable.
In winter cold weather, this application selects the natural gas earlier as burning medium start-up boiler, and the clean water temperature in the preheating chamber 11 risees after the boiler starts, and heating coil 17 is gone into with the clean water pump 4 in the preheating chamber 11 to water pump 4, and this process can preheat diesel tank 8, makes the wax melting. However, the heat value of the natural gas is lower than that of the diesel oil, the diesel oil tank 8 is heated by the heat tracing coil 18 until wax is melted, the diesel oil is switched to be used as a combustion medium, heat generation is increased, the hot water or steam generation speed is increased, and therefore the effect of cleaning the oil pipe is improved.
The upper end of the flue 15 is provided with a rotatable air duct 13, the upper end of the flue 15 is communicated with the side wall of the air duct 13, and the diameter of the air duct 13 is larger than that of the flue 15, so that the smoke exhaust effect is not lower than the original smoke exhaust effect.
One end of the air duct 13 is fixedly connected with a horn-shaped air-collecting cover 12, and the air-collecting cover 12 rotates through manual adjustment or automatic adjustment, so that the opening direction of the air-collecting cover is always windward. Compared with the prior art, the design of the wind collecting cover 12 and the wind barrel 13 in the application has two effects; firstly, the smoke exhaust effect of the flue 15 is improved, so that the combusted smoke can be discharged in time, and the mixed combustion effect of the fuel and the air in the combustion chamber 16 is favorably improved; secondly, rain-proof effect promotes obviously, avoids the rainwater to persist and causes the erosion to metal material's flue 15.
Since a large amount of soot particles are generated during the combustion process of the oil-fired boiler, a purifier 14 is fixedly connected to the other end of the air duct 13 to purify the exhaust smoke.
Furnace body 1, steam package 3, water pump 4, diesel tank 8, switch board 5, generating set 6 and gas pitcher 9 be located bicycle shed 2, bicycle shed 2 forms effectual protection, prevents the erosion of illumination and rainwater to equipment.
