MonoBlock Burner (MB Series)The burner works fully automatically, and does not require any permanent control. The connected regulation of heat output and low access of air during combustion ensure highly efficient operation. The burner is designed as a monoblock and thus the ventilator is a part of the burner’s main body.

Dual Block Burners (DB Series)

Premixed BurnersCondensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted. n a conventional boiler, fuel is burned and the hot gases produced pass through a heat exchanger where much of their heat is transferred to water, thus raising the water’s temperature. One of the hot gases produced in the combustion process is water vapour (steam), which arises from burning the hydrogen content of the fuel. A condensing boiler extracts additional heat from the waste gases by condensing this water vapour to liquid water, thus recovering its latent heat of vaporization. A typical increase of efficiency can be as much as 10-12%.[citation needed] While the effectiveness of the condensing process varies depending on the temperature of the water returning to the boiler, it is always at least as efficient as a non-condensing boiler.

Water Tube BurnerWater Tube Boilers The ability of water tube boilers to be designed without the use of excessively large and thick-walled pressure vessels makes these boilers particularly attractive in applications that require dry, high-pressure, high-energy steam, including steam turbine power generation. Owing to their superb working properties, the use of water tube boilers is highly preferred in the following major areas: Variety of process applications in industries Chemical processing divisions Pulp and Paper manufacturing plants Refining units Power Plants Besides, they are frequently employed in power generation plants where large quantities of steam (ranging up to 500 kg/s) having high pressures i.e. approximately 16 megapascals (160 bar) and high temperatures reaching up to 550°C are generally required. A water tube boiler can be defined as a Steam boiler in which the flow of water in the tubes, as well as hot gases, enclose the tubes. Not like fire tube boilers, this boiler attains high-pressures, as well as high-steam capabilities, can be achieved. This is because of condensed tangential pressure on tubes which is known as hoop stress.

Heavy Oil Heater (OH Series)

Burner Ventilation Motor Starter (RMS)Raadman burners ventilation motor starter raadman factory produces burners with firing range of 100 kW to 60000 kW. In burners with ventilation motor capacity of 22kW and above, the power circuit and control circuit need to be installed separately due to destructive effects of electrical noise that power circuit or high voltage has on the control devices. With Regard to this reason, raadman motor starter (RMS) in which the power circuit is embedded, is introduced by the means of this technical document. Different starting methods Star-Delta (Picture 1): A star-delta starter is the most commonly used method for starting a three-phase induction motor. In star delta starting, an induction motor is connected via a star connection throughout the starting period. In order to use this starting method, the motor must be delta connected during a normal run. This starting system has some disadvantages that are mentioned below: -Overload current drawn from electric grid at the time of starting -Current and mechanical shocks at the load torque starting moment -Current and mechanical shocks to the motor at the moment of changing status from Star to Delta which reduces the motor useful lifespan -by increasing the current range, the contactors and bimetals sizes are increased Soft Starter…
