Abstract
The invention discloses an ignition method for a boiler by utilizing methyl alcohol. The ignition method for the boiler by utilizing the methyl alcohol comprises the following steps of A, storing the methyl alcohol into a methyl alcohol storage tank after filtering through a methyl alcohol primary filter; B, pumping the methyl alcohol in the methyl alcohol storage tank into a fine filter through a methyl alcohol pump to be filtered and pumping the filtered methyl alcohol into an atomizing nozzle; C, conveying steam from the boiler to the atomizing nozzle to be mixed with the methyl alcohol in the atomizing nozzle and enabling the methyl alcohol to be warmed to atomize; D, mixing the atomized and warmed methyl alcohol and air to be conveyed to the boiler and igniting. The ignition method for the boiler by utilizing the methyl alcohol has the advantages of reducing primary investment and operation costs, effectively improving the operation response speed, enabling combustion products to not to pollute the atmosphere and achieving energy saving and environmental friendly purposes.
Description
Technical field
The invention belongs to boiler technology field, be specifically related to a kind of method that methyl alcohol is ignition of the boiler of utilizing.
Background technology
At present, the igniting of large-sized boiler and steady combustion are all to adopt combustion fuel oil to realize traditionally, and in recent years, along with global energy shortage, price of fuel oil rises steadily, and thermal power generation fuel oil is more and more restricted.Therefore ignition of the boiler and stable combustion oil are used as a kind of important index and examine, in order to reduce the consumption of fuel oil, traditional way is to improve the fineness of coal dust, improve the preheat temperature of wind powder mixture and Secondary Air, adopt pre-combustion chamber burner, select little atomizer igniting etc., but, if to further reduce fuel oil to finally need not oil, necessary employing and traditionally diverse brand-new technique, this technique both can guarantee to improve the economy of combustion process, can improve again the ecological condition of power plant.
Summary of the invention
The object of the present invention is to provide a kind of method that methyl alcohol is ignition of the boiler of utilizing, replace existing boiler oil sparking mode, reduce operating cost, improve operation response speed.
For realizing above object, the invention provides a kind of method that methyl alcohol is ignition of the boiler of utilizing, specifically comprise the steps:
Steps A: methyl alcohol is stored in methyl alcohol fluid reservoir after methyl alcohol coarse filter filters;
Step B: by methanol pump, the methyl alcohol in methyl alcohol fluid reservoir is squeezed into methyl alcohol fine filtrator and filter, and squeeze in atomizer;
Step C: the steam from boiler is sent in atomizer, and the methyl alcohol in atomizer mixes and makes methyl alcohol intensification atomization;
Step D: the methyl alcohol after atomization is heated up and air mix sends into boiler igniting.
Further, the given speed of the methyl alcohol in this method and steam is all adjustable.Can realize the adjusting of igniting effect, adapt to different process condition.
Beneficial effect of the present invention is: utilize methanol liquid to replace the oily sparking mode of existing boiler, reduce oil mass consumption, reduce ignition of the boiler investment, and then effectively reduced the operating cost of boiler plant.The flash-point of methyl alcohol is low, can make the preheat temperature need not be too high, and igniting operation response is fast, sufficient combustion, and product is pollution-free to atmosphere; And the price of methyl alcohol is approximately oil price half, well below oil price.Therefore, the present invention has not only effectively reduced investment and the operating cost of equipment, and igniting operation response is fast, and combustion products is pollution-free to atmosphere, energy-conserving and environment-protective.
