Description
Technical Field
The utility model relates to a gasifier technical field particularly, relates to a gasifier furnace end.
Background
As the fuel of household cooking utensils, coal gas, liquefied petroleum gas and methane are the most convenient and economical. But all are limited by regions and supply conditions, and are difficult to popularize in a large amount in the near future. But the geological exploration groups, well platforms, fishermen and herdsmen with larger mobility are more limited, and the geological exploration groups, the well platforms, the fishermen and the herdsmen can only adopt coal, firewood and even wood. The combustion mode of the fuels cannot be fully completed, the heat efficiency is extremely low, resources are greatly wasted, the environment is polluted, and the use and the transportation are difficult. The oil burner shows its advantages. The oil-fired furnace has two kinds of kerosene and diesel oil furnaces, and the kerosene has distillation temperature of only 205-. An old kerosene stove with a cotton core and a new kerosene gasification stove. However, the kerosene production is low, the supply amount is limited, and the kerosene is difficult to be widely applied.
Diesel oil (referred to as light diesel oil) accounts for a considerable proportion of petroleum products, and is distributed throughout urban and rural areas, field exploration teams, well platforms, fishing boats and grasslands. The diesel oil has wide supply range, higher heat value than kerosene and lower price than kerosene. Therefore, in recent years, various types of diesel furnaces have been developed. However, the distillation temperature (355-365 ℃) of the diesel oil is higher than that of the kerosene, the volatile components are less, ash content (about 0.025%) is present, the colloid is 70 mg per 100 ml, the flash point is high (the closed opening is not lower than 60 ℃), the ignition is difficult, and the combustion smoke intensity is high, so that the diesel oil can obtain practical value and obtain ideal effect only by adopting a vaporization combustion mode.
In order to reasonably utilize petroleum resources and utilize the high thermal efficiency and the economy, the development of the diesel gasification furnace has wide prospect. The burner is an important component of the gasification furnace, the combustion of fuel, the direction and shape of flame and the discharge of waste gas are all related to the structure of the burner, and in addition, the heating of charging, the smelting time, the consumption of fuel and the like are all directly influenced by the structure of the burner, so that the correct selection of the size of the burner and the regular maintenance work have very important significance.
The existing gasification mode of the furnace end is a gasifier with a front air inlet, which is used for gasifying diesel oil, the gasified diesel oil is conveyed to a gas outlet of the furnace end to be combusted, and the diesel oil is gasified only by the gasifier, so that the problem of low gasification conversion efficiency exists, and the diesel oil cannot be fully combusted.
In summary, we propose a gasifier head to solve the above technical problems.
