Fuels oils - and their viscosities versus temperature. Sponsored Links. Saybolt Universal Seconds - SSU - viscosity versus temperature for typical fuel oils: TF = TC 9 / 5 + 32. SSU (Saybolt Universal Seconds) = centiStokes (cSt) x 4.55 1) 4 - 5000 SSU is the maximum …
1. Scope. 1.1 This specification covers four grades of fuel oil made of at least 25 % used lubricating oils. The four grades of fuel are intended for use in various types of fuel-oil-burning industrial equipment and commercial boilers under various climatic and operating conditions. These fuels are not intended for use in residential heaters.
2/5/2014 · The basic principle of the Viscotherm viscosity monitoring device or viscosity controller is shown in the figure below. A continuous sample of the fuel is pumped at a constant rate through a fine capillary tube. As the flow through the tube is laminar, pressure drop across the tube is proportional to viscosity.
11/7/2009 · Viscosity Regulator or Viscotherm, is a device used to measure viscosity of the fuel oil before sending it to the engine. It is generally fitted at the outlet of the fuel oil heater. The regulator is connected with the heater so that it can measure the viscosity of the oil
The viscosity of oil varies with temperature: the hotter the oil, the more easily it flows. Indeed, most people are aware that heavy fuel oils need to be heated in order to flow freely. What is not so obvious is that a variation in temperature, and hence viscosity, will have an effect on the size of the oil particle produced at the burner nozzle.

30/4/2014 · Rotary or spinning cup jet boiler fuel oil atomizers. Figure below shows the arrangement in principle. It consists of a motor driven fan, metering pump and fuel cup. The fuel cup which rotates at 70 to 100 rev/second is supplied with oil at low pressure (1.7 to 4.5 bar) from the metering pump which is used to control the throughput. Due to
Viscosity is an important fuel property of any fuel oil specification as it influences the degree of pre heat required for handling, storage and satisfactory atomization. If the oil is too viscous it may
heavy fuel oil significantly in accordance with the SOx emission standard that will start in 2020. When the low dynamic viscosity fuel oil is used, it may be necessary to replace a fuel oil temperature sensor installed on our boilers and other equipment for issuing

Fuel Oil Gross Calorific Value (kCal/kg) Kerosene - 11,100 Diesel Oil - 10,800 L.D.O - 10,700 Furnace Oil - 10,500 LSHS - 10,600 Sulphur The amount of sulphur in the fuel oil depends mainly on the source of the crude oil and to a lesser extent on the refining
Viscosity Control for Marine Fuel Oil. The measuring of oxygen content in an atmosphere is important, particularly when entering enclosed spaces. Also inert gas systems use exhaust gases which must be monitored to ensure that their oxygen content is below 5%. One type of instrument used to measure oxygen content utilises the fact that oxygen is
Today, almost all marine fuels are based on fractions from more advanced refinery processes and the viscosity itself says little about the oil's quality as fuel. Despite this, marine fuels are still quoted on the international bunker markets with their maximum viscosity set by ISO 8217 as marine engines are designed to use different viscosities of fuel.
Fuel oil viscosity explained - The need to regulate
Raw materials - heavy natural oil. The initial viscosity is 197.8 centipoise. Oil viscosity after a single treatment (without additives and solvents) - 156 - 159 centipauses. The same processed samples after 15.
burners in a boiler receive a fuel oil with high viscosity, atomiza-tion results in larger drops. In contrast, if the fuel arrives at the burners with low viscosity, the atomization results in smaller droplets. With larger oil droplets, an incomplete combustion reaction takes
