Bolt heaters are used to expand the stud bolts around the main steam and condenser chests in a turbine set, in order that the nuts may be slackened or tightened to the high degree of control necessary.
In detail design, the heaters are of extremely robust construction. Tubular sheathed elements are sintered in a stainless steel outer tube of accurate outside diameter to fit into standard bores machined in the full length of the stud bolts. Heater tube diameters range in seven steps from 0.625″ to 1.438″ with lengths from 12″ to 60″ and loadings from 500W to 10kW.
Spare heater blades (sintered assemblies) can be readily screwed into the boxes when replacement becomes necessary. Two standard sizes of terminal box are used to cover the range, these having maximum current ratings of 30amps to 100amps.
To meet the safety regulations appropriate to the handling of heater tools of this type, the electrical connection to the terminal box is made via the approved Harvey-
Normally, a number of heaters are fed from specially designed 415v/110v supply transformer trolleys fitted with outlet sockets backed up by fuses, earth fault relay, contactor control circuit and voltage indication.

The electric melting of solf metals is usually carried out in specifically designed pots or baths which are heated either externally, by conduction or fitted with an over the side immersion heater
Consolidated Technology sells both types of heater, but there are five reasons why the immersion heater is the more efficient method:
1. The element comes into direct contact with the metal:hence 100% heat transfer
2. The element is inside the pot and does not interfere with lagging; hence smaller heat losses
3. The heater is easily installed and can be fitted singly or built up into banks for larger installations –
4. The heater is easily accessible for maintenance: avoids inconvenience
5. Elements can be replaced should they fail in the severe corrosive environment and the metal plates can be reused or simply replaced: saves money.

SQUARE COIL HEATERS (SQ5 & SQ7)
All elements we supply consist of a nickel/chromium resistance spiral insulated by compacted magnesium oxide powder from a metal outer sheath. This sheath may be of steel, copper, nickel or other material depending on the application.
The robust construction of our Standard and Special elements, together with the ability to form them into the most complex shapes with a minimum of tools, makes them the ideal choice for applications up to 800°C.
Whether your requirement is for a simple 1000 watt heater or sophisticated plant running into Megawatts, our elements can provide the answer.

• A wide range of terminations is available, these include 2BA screw, 4BA screw, pillar and tailwire.
• Elements can be manufactured in lengths, loadings, diameters and sheath material to suit almost any material.
• The forming of elements can be achieved with a minimum of tools. Standard straight lengths are supplied fully annealed to facilitate forming.
• Elements can be gilled in order to increase the heat dissipation, this is particularly useful in the case of air and gas heating.
• All elements may be brazed to supports or flanges, welding is also possible with some sheath materials.
Vat Heaters
Many industrial processes today depend on the use of heated solutions contained in open vats or vessels. In these conditions our extensive range of over-
• Mild Steel • Lead • Stainless Steel EN 58J (Type 316) • Titanium • P.T.F.E
In each sheath material (excluding PTFE) five different combinations of length and loadings are offered as standard. Due to the vast range of solutions used in industry today it is impossible to give any meaningful guide as to the suitability of the various sheaths. The composition as well as the working temperature of the solution are of great importance and it is recommended that you consult us for advice if you are in any doubt. In some cases sheaths can only be proved by trial.

Before removing heaters from a tank, they should be switched off and electrically isolated and remain immersed for a suitable period to ensure no undue temperature rise that may contribute to permanent failure.
Metal sheathed and Teflon coated heaters must be effectively earthed and be installed in accordance to current IEE wiring regulations for electrical installations.
To provide enhanced operator protection, it is recommended that a suitable residual current device with rated tripping current of 30mA or less be incorporated in the supply to the heater.
Further guidance on the installation and use of immersion heaters is available in the BNCE ‘Safety Guidelines for Industrial Electric Immersion Heaters’.
