Embodiment Construction

[0018] The invention is an additive mainly composed of water, wherein the nonylphenol polyoxyethylene ether (trade name TX-10) and the sulfate salt of 0.2‰ to 0.32‰ are added in the amount of water of 0.4‰ to 0.64‰. TX-10 makes water and heavy oil blend together without separation. The sulfate may be potassium sulfate, zinc sulfate, cobalt sulfate, manganese sulfate, nickel sulfate, iron sulfate, chromium sulfate or magnesium sulfate. The addition amount of the present invention is 30-50% of heavy oil weight. When adding, first heat the heavy oil to about 70°C, add the present invention according to demand and stir together for 3 to 5 minutes, then it can be put into use, and the rotating speed of the mixer is 1450 rpm.

[0019] Add the heavy oil of the present invention with 100: 36 weight percents, in 1.5Mpa, 4 tons of steam boilers are through burning test for several days continuously, confirm that the present invention makes heavy oil fluidity greatly improved, does not ...

Abstract

A heavy oil additive for decreasing viscosity, smoke and carbon deposit and improving flowability contains nonylphenol polyoxyvinylether (0.04-0.064 wt%), sulfate (0.02-0.032) and water (rest). Its dosage is 30-50% of heavy oil weight.

Description

Technical field: [0001] The invention relates to substances added to fuels for improving fluidity and reducing smog and carbon scale, especially as additives for heavy oil used as fuel for boilers, kilns and stoves. Background technique: [0002] The price of heavy oil is low, the source is wide, and it has a certain calorific value, so it is widely used as fuel for boilers, kilns, and stoves. my country consumes about 100 million tons of heavy oil every year. A major feature of heavy oil is its high viscosity, and heating equipment must be used to improve its fluidity. But even so, the atomization state of its spray from the nozzle is not good, coupled with the high carbon content of heavy oil, so its burning smoke is large, polluting the environment, and the carbon deposition of the equipment is serious. Therefore, general kilns are far away from residential areas, and for many domestic boilers built in residential areas, it is necessary to increase smoke and dust remova...
