Description
Technical field
The utility model relates to oil-fired system match equipment technical field.More specifically, a kind of novel fuel heater is related to.
Background technique
Fuel heater is as a kind of heating equipment starting preheating under indoor intensification and vehicle low temperature, be utilize fuel (gasoline, diesel oil or kerosene etc.) burn the direct heat medium of produced heat (being generally cooling liquid) in special combustion heating machanism, after medium circulation is flowed, remove the device of heating or warm-up the engine.
Automobile oil heater results from the Europe of the forties in 20th century the earliest, is mainly used in also confession lorry cab heating or the heating of passenger car room of warm-up the engine in winter.Thereafter product spreads all over rapidly Europe and North America market.It is more late that development is compared in the automobile oil heater of China and Europe and North America.Along with the raising that the increasingly strict of external environmental regulation and passenger's riding comfort require, the air-conditioning technical in automotive regulation controls the fuel oil of fuel heater, emission control and noise control etc. are had higher requirement.
The fuel heater working principle of producing both at home and abroad is at present as follows:
Motor drives oil pump, combustion fan and atomizer to rotate.The fuel oil that oil pump sucks delivers to atomizer through transport pipe, mix in main combustion chamber with the air that combustion fan sucks after atomization, lighted by red-hot glow plug, turn back after the combustion of firing chamber, through the radiating fin of water jacket inwall, heat is passed to the cooling medium in water jacket samdwich; Heated medium, under the effect of water pump (or thermoconvection), circulates in whole pipe-line system, reaches the object of heating.The waste gas that burning produces is discharged by smoke exhaust port.
This combustion principle will inevitably bring a series of inevitable problem:
1. fuel-oil atmozation problem: fuel oil (comprising gasoline, diesel oil, kerosene etc.) is Yi Zhong Duo Hydrocarbon material, is namely formed by multiple flammable molecular combinations.When fuel oil is not when reaching its gasification temperature, these are flammable, and molecule in close combines; Although fuel oil is decomposed very tiny material with various atomization method (as high-pressure injection atomization or centrifugal spraying) by people, but this physical method does not change its intrinsic substance characteristics all the time, remain many hydrocarbon materials that various flammable molecule in close combines.This material demand outside combined by many combustible gases molecule in close gives comparatively macro-energy makes it resolve into after each independent molecule just incendivity (as glow plug etc.), so general ignition is difficult to be lighted.
2. combustion-supporting air problem: fuel oil also has a characteristic, under external energy (as glow plug etc.), be namely broken down into each independently while flammable molecule, its volume will expand hundreds of times instantaneously.Although the fuel heater of routine is configured with special combustion fan, due to combustible substance moment volume acutely expand, the combustion-supporting air that combustion fan sucks far can not meet the requirement of 15:1 within the unit time.
3. combustion problem: because combustion oil gasification and burning carry out in moment simultaneously, internal pressure of combustion chamber can increase suddenly in moment, and air-flow from the fast discharge of smokejack, causes heat energy shorter in the firing chamber waiting time with a large amount of heat energy.
4. emission problem: the ratio of combustion-supporting air and inflammable gas can not meet clean-burning condition, greatly inflammable gas must be had can not burn and enter air along with gas of combustion, therefore can cause in combustion gas containing more CO and hydrocarbon.
5. noise problem: produce larger detonation sound when this combustion manner will inevitably cause fuel oil sharply to gasify in firing chamber
6. power load problem: this combustion manner needs larger power load in start-up course, working state, closing process, oil pump as larger in power, combustion fan and atomizer motor, glow plug, fuel taps etc. are as larger to automobile storage battery electric power consumption in being applied to when north of china in winter automobile parking is warmed oneself.
To sum up the usual fuel oil heater has the following disadvantages: low efficiency;Fire poor stability;Low temperature starting ability is poor;Unit consumption electric calabash electricity;Large noise;Exhaust emissions;Complex high failure rate;Series of problems are the main reason is that no separate gasification and combustion of fuel for the results.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of novel fuel device, and combustion oil gasification and burning, using gasoline, diesel oil, kerosene as fuel, are separately carried out, made fuel oil Thorough combustion, reduce harmful exhaust emissions by this oil burner; Many hydrocarbon mixtures fuel oil is gasified totally into independent inflammable molecular gas, lights a fire as use general gas, burn; Be different from the combustion manner that gasification-instancy of combustion that existing fuel heater adopts carries out simultaneously; And easy at low temperatures ignition trigger, catch fire stable, reduce device power load, structure is simple, and micro-noise when startup, work, closing process, low emission, combustion efficiency is high.
