Limpet coil reactor vessels are used to control the temperature of the reactants with the help of heating or cooling media circulated through coils surrounding the main vessel. Ideally suitable for medium heat transfer requirement and heating application where heating media temperature is above 200 Centigrade.

What is double limpet coil?
Double Limpet Means One Four Thermic Fluid or Second For Cold Water , one for heating and second for cooling. Top side provide you motor and gear box for agitation purpose , agitator blade is different as per requirement like anchor , flat blade , twisted blade , high speed also we can do .
What is limpet in vessel?
Limpet Coil is Half round Pipes welded on the outer surface of the shell and also on the bottom dish of the Reactor. Limpet coil is made of either Mild Steel Or Stainless Steel. It is either Double end double start for both heating and cooling through limpet coil or Normal Single coil for either heating or cooling.
How do you calculate limpet coil heat transfer area?
How to Calculate Length of Limpet Coil
- Shell OD (Do) ‘mm’ = Shell ID (Di) ‘mm’ + 2x Vessel Thickness (tv) ‘mm’
- Continuous Limpet Coil Size = LMC (NB)* x (t) ‘mm’
- Number of Turns required on the shell (#T) = Limpet Jacket Height (HL) ‘mm’ / Pitch (P) ‘mm’
How do you calculate coil length?
To obtain the coil length we have to divide the result by the section of the coil determined by coil width and thickness. The coefficient 1000 is used to compensate the dimensions in [mm] with the length in [m]. For example, a coil with OD = 1600mm, ID = 508mm and T = 0,6mm results in a length of 3010 meters.
How do you size a heating coil?
To solve the basic equation (A = Q/U T), you must first determine the value of Q, or the total heat input needed to elevate the solution temperature to a final temperature. Q is usually measured in Btus, which is the amount of heat needed to heat one pound of water one degree F.
How do you calculate the area of a coil?
Example of using the helical coil calculator
- Enter coil diameter, Dc = 10 mm .
- Fill in the wire diameter, Dw = 0.5 mm .
- Insert the number of turns in the coil, N = 15 .
- Enter the coil spacing or pitch, S = 0.3 mm .
- Using the length of helical coil formula: Lw = π * Dc * N = π * 10 * 15 = 471.2 mm.
What is coil length?
To calculate spring wire length per coil, you must subtract the wire diameter from the outer diameter in order to get mean diameter. Once you have calculated mean diameter, multiply it by pi (3.14); this will give you the length of wire per coil.
How many meters is a coil?
1 Sq.mm Fire Retardent (fr) V Gaurd 1 Sq.mm Fr House Wire 90 Meters Packing Coil, Rs 668 /meter, ID: 15010121333.
How heavy is a coil of steel?
between about 7 to 15 tons
Each coil usually weighs between about 7 to 15 tons depending on the length and thickness of the plating. Coils weighing up to 30 tons are not altogether uncommon.
How do you calculate reheat load?
Heat load (BTU) = Length (m) x Width (m) x Height (m) x 141. So, for a room measuring 5m x 4m x 3m = 60 > x 141 = 8,460 BTU. (For measurements in feet, the formula becomes: Heat load (BTU) = Length (m) x Width (m) x Height (m) x 4)
What is meant by off coil temperature?
– Off Coil temperature is the Air leaving temperature after cooling coil. It is a constant value with high Relative humidity. We can pass this Air through dehumidifier to control the humidity in Air.
How is evaporator capacity calculated?
If the evaporator must move 400 gallons per minute: 14 x 400 = 5,600. Multiply the answer by 500: 5,600 x 500 = 2,800,000. This answer is the evaporator’s size, measured in BTUs per hour. Divide the answer by 12,000: 2,800,000 / 12,000 = 233.33.
How do you calculate volume of a coil?
To estimate soil volume for any area, all you need is a tape measure. “The basic formula is simple: Length x Width x Height = Volume,” says Michael Dean, co-founder of Pool Research. Then divide the number of cubic feet by 27. So one cubic yard = 27 cubic feet = 1,728 cubic inches.
What is Loop area?
Hence, the area of the loop lying in the positive quadrant =21∫03πr2dθ =2a2∫02πsin2ϕ⋅31dϕ [On putting, 3θ=ϕ⇒dθ=31dϕ]
What is inductance of a coil?
Inductance is greater when the number of turns of wire in the coil is greater. More coils of wires indicate a greater amount of magnetic field force for a given amount of coil current. Coil Area. Inductance is proportional to the coil area. Greater the coil area, the greater the inductance.
How do you calculate coil density?
Solenoid Magnetic Field Calculation
For a solenoid of length L = m with N = turns, the turn density is n=N/L= turns/m.
What is coil wire?
coil, in an electric circuit, one or more turns, usually roughly circular or cylindrical, of current-carrying wire designed to produce a magnetic field or to provide electrical resistance or inductance; in the latter case, a coil is also called a choke coil (see also inductance).
What is steel coil used for?
Steel coils are used by various industries, as this type of metal is ideal for building panels, walls, roof panels, power stations, ships, and various other projects and construction undertakings. In addition to different sizes of steel coils, there are also two different primary types: Cold-rolled steel coils.
How big is a coil of steel?
A flat rolled steel coil is a type of metal sheet wound into rolls, the width of which is larger than the thickness. Our flat rolled steel coils at Hascall Steel Company specifically have widths of ½ inch to 72 inches, with thickness ranging from 0.010 to 0.325.
What is the length of one coil wire?
1 Coil – 90 mtr or 295.29 Feet.
