Even if NG plants burn with greater efficiency than your average boiler, electrical distribution losses probably wash out that benefit. Inductive heating can never be more efficient than a resistive heating element immersed in the water. That is basically 100% efficient.
Typical resistive loads are heating elements in water heaters, etc. A 'reactive' load is one which results in a load current that either lags (inductive) or leads (capacitive) the supply voltage.

We exercise energy on a load, which might be: pure resistive (like in a boiler resistance) inductive (as in an electric motor) and capacitive (some ultrasound generators).
Nov 19, 2007 · Answers. Inductance is normally associated with circuit elements called coils and a coil`s inductance value is measured in units called henrys. Inductive reactance in a coil is directly proportional to the inductance value in Henrys and also directly proportional to the frequency of the applied ac voltage.

During the boiler operation, once the system start-up is over, students can observe the operating batch mode of the boiler (video V0); first, the steam pressure increases from 2.5 to 7.5 bars, then the boiler stops, the steam pressure decreases to 2.5 bars, and a new cycle begins. Students realize that when the steam pressure is increasing, there is a fluid flow-rate in the five streams associated with the boiler.
A new induction water heating system design for domestic heating. In this way, while solar power is benefited at the highest level, the desired room temperature can be achieved easily through the boiler having low resistance power. However, due to failure of resistances at short intervals and the need of laborious effort during the changing process,
AC waveforms are usually sinusoids. Loads are of three types. Resistive, inductive, capacitive. When the load is resisitive, the voltage and the current waveforms are in phase with each other. If it is inductive, current lags the voltage and if it is capacitive, current leads the voltage.
C = capacitance (farad) For a capacitive load the current in an AC circuit leads the voltage by π/2 (90o) phase. In a real electrical circuit there is a mix of resistive, capacitive and inductive loads with a voltage/current phase shift in the range -π/2 <= φ <= π/2 as illustrated in the figure below.
removed will cause scaling and corrosion in plant equipment, particularly in heat exchangers, cooling towers, and boilers. There are many ways to treat water, and different treatments have different goals. Often the goal is demineralization, which is the removal of all or nearly all of the contaminants. In
Plus, it limits a plant's ability to expand production and is expensive to install, maintain, and operate. Generating heat right in-line with a production process lets manufacturers focus on making quality food & beverage products instead of spending time and resources maintaining a central steam utility.

The efficiency of the boiler is a measurable value presented as the ratio between the energy that was produced by the boiler and the energy that the boiler used for combustion of fuel. Maintaining the efficiency of the steam boiler can be achieved by keeping the combustion process under constant control , by cleanness of the heating surfaces and by the good insulation of the boiler .

1 min ago steam boiler for a power station 1 min ago steam boiler 3 ton capacity from turkey is a boiler plant resistive or inductive;
Energy transfer in an inductive heater happens only due to the coupling of the primary inductance with the secondary load, which appears as a weakly coupled inductive load with a near-dead-short across the coil. You can see an attempt to reverse-engineer a commercially available induction cooker here, which includes a SPICE simulation.

Jan 09, 2018 · The power is measured in V.A or watts, this may be experssed in terms of R but only because the resistance determines the current flow for a specified Voltage. Obviously, if it is a circuit containing capacitive and inductive loads, then a proport
Inductive Load. An inductive load causes the current wave to lag the voltage wave. Thus, power factor of an inductive load is lagging. Examples of inductive load include transformers, motors, coils etc. Combination Loads. Most of the loads are not purely resistive or purely capacitive or purely inductive.
Apr 24, 2017 · When electricity flows through a circuit, there are points on the circuit, called loads, where energy is drawn away. Loads, in essence, are objects that use electricity--such as light bulbs. There are a variety of classification systems, but one way you can divide loads is into resistive, capacative, inductive or a combination of these types.

Answer to A small industrial plant has a 10 kW heating load (purely resistive) and 20 kVA inductive motor load. The motor load its
In fact, resistance and current are inversely proportional in this case: if one doubles, the other is halved. What, then, is the effect of resistance on power consumption? The key here is that resistive heating depends on the square of the current, meaning that the power is more sensitive to changes in current than resistance.

Methods of electric heating include resistance heating, electric arc heating, induction heating, and dielectric heating. In some processes (for example, arc welding), electric current is directly applied to the workpiece. In other processes, heat is produced within the workpiece by induction or dielectric losses. As well, heat can be produced then transferred to the work by conduction, convection or radiation.

Thermal-based power plants can produce electricity from coal or other fuel sources. The coal-fired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2.
