The design and manufacturing of the burners is based on economy, safety, and service as well as environmental friendliness. We supply burners complying with various marine classification society requirements, such as S, V, CCS, DNV, GL, KR, LR, NKK, RIN and RS. Construction ll burner components are mounted directly on the burner housing. The burner housing incorporates a three-phase motor that runs the fan and the oil pump. The surface of the housing is finished with durable high-gloss paint. The housing is equipped with a hinged burner flange with a safety interlock switch, enabling the burner to be swung open to the left or right. Due to the burner flange, it is possible to service the combustion head, nozzles, and ignition electrodes without removing the burner. The stainless steel alloy combustion head and the diffuser disc can withstand temperatures up to 1,0 C. The combustion head is adjustable, to optimise the mixing of fuel regardless of the firing rate. The burner contains a sight glass for flame observation. On the suction side of the fan there is an air damper that, together with the servomotor, automatically controls the amount of fuel and air on the basis of the firing rate required. removable upper cover makes electrical installations and burner servicing easier. Installation and suitable applications The burners are suitable for steam and hot water boilers. They are also designed to suit furnaces with high back pressure. The burners can be mounted in horizontal or vertical downward-facing orientation. Our burners are designed for operation in covered areas, max. +0 C. Fuels - heavy fuel oil, viscosity max. 30 mm /s, +0 C (max. for RP-90 H) additional heating cartridge for pump and nozzle - heavy fuel oil, viscosity max. 00 mm /s at + 0 C for H/T burners, 700 mm /s at + 0 C for burners additional heating cartridges as above + trace heating for the oil piping and oil hoses - marine diesel ol (DO) - light fuel oil Capacity regulation methods Depending on the model, options to choose from are: Two-stage, H Three-stage, T odulating, The two- and three-stage burners are equipped with an air damper servomotor, run time of which is seconds between capacity stages. The burners automatically operate as one-, two-, or threestage according to the load. odulating burners are equipped with a servomotor with a transition time of 30 sec/90. The servomotor is connected to the oil regulator and compound regulator via an axle. modulating burner operates regardless of the firing rate, on the basis of the load. The burners are commissioned on the basis of combustion gas analysis. Oilon preheater guarantees accurate oil temperature control ll models are equipped with necessary oil shut-off valves and a filter, and with an electric mass preheater. The preheater is controlled via an electronic regulator that keeps the oil temperature stable. Stable oil temperature makes it easier to obtain optimal combustion conditions. In the heavy oil burners, the oil heated during the pre-purge phase flows to the nozzle through the preheater to ensure that the oil temperature is high enough during the ignition phase. Please notice, that preheater capacity varies by voltages. Oil piping ounted on the burner, three-stage burners with four solenoid valves (one main valve and one valve for each nozzle) equipped with heating cartridges. odulating burners have four solenoid valves. The oil regulator for the modulating burner is located on the oil line returning from the nozzle. The oil filter is located on the suction side of the pump. The two oil hoses enable the burner to be hinged. Flame monitoring ll models are equipped with automatic flame monitoring. On request, an extra flame detector for manual use, can be installed. Silencer The sound level of the burners is low, but, if desired, they can be equipped with a separate silencer to make them even quieter. We reserve the right to make technical alterations.

4 How to choose a burner 3. Procedure 1 Establish relevant boiler and application information boiler capacity and efficiency, or required burner capacity in kw or in overall pressure loss in mbar, mmwc (mmh O) or Pa. Establish relevant fuel information viscosity impurities 3 Calculate the burner capacity. urner capacity = boiler capacity / efficiency Example: boiler capacity of 1,00 kw, efficiency of 0 % burner capacity = 1,00 kw / 0. = 1,70 kw. Calculate the required oil flow []. Required oil flow [] = (burner capacity [kw] x 3.) / the oil s calorific heat value [J/kg]. Example: required burner capacity = 170 kw required oil flow = (1,70 kw x 3.) / 0. J/kg = 1, where 0. J/kg is the calorific heat value of heavy fuel oil.. See the brochure for burner capacity/back pressure graphs: The graphs indicate the operating range of the burner. The colour filled curve is for + C operating condition (typical ambient condition in ship), the curve with dashed line is the standard (EN7) curve. For example, the back pressure of a boiler with a burner capacity of 1 oil is mbar. When you look at the point at the co-ordinates for 1 and 7 mbar on the colour filled graph at the bottom of the page, you can see that the point is located within the capacity/back pressure area for RP- H or RP- burner. When the point representing the required back pressure and capacity is located within the indicated area, the burner capacity is adequate. The best size of burner can be selected by choosing a burner for which the point is located as near the right-hand edge as possible. The calorific heat value of the fuel is indicated in conjunction with the graphs.. Check that the outer dimensions of the burner, especially those of the combustion head, are suitable for the application; the length of the combustion head should be such that, when mounted, the combustion head is even with the furnace wall or about to mm inside the furnace (see asonry figure). Quick selection oiler capacity [ ton/h ] urner capacity [] min. ring line pumping unit capacity [] 7. Calculate minimum ring line pumping unit capacity. The minimum capacity is [] = ((oil flow to be burned in ) + 10 )* 1.. Example: required ring line pumping unit capacity []= ( ) * 1,1 = 3. Fuel pressure to the burner (ring line pressure) For H-burners 3, bar For T-burners 3, bar For -burners 3, bar Temperature to burner (ring line oil temperature) should be + 0 C 0 C with HFO. Note! In case the power is more than 390 with 00V 0 Hz or 70 with 0 V 0 Hz, additional heater may be needed.. Equations and rules of thumb 1. Steam boilers: 1 ton/h steam ~ 7 (HFO) burner capacity. Light oil: 1 ~ 11. kw burner capacity with calorific value.7 J/kg 3. Heavy oil: 1 ~ 11. kw burner capacity with calorific value 0. J/kg. The amount of combustion air: Oil burners: required amount of combustion air for each kilo of oil burned [] is 13. m 3 /h. n example of burner selection RP- H Required burner capacity is 1 and overall pressure loss 7 mbar.

15 urner preheater ccurate temperature control guarantees good combustion In burning heavy fuel oil, the right atomising viscosity of the oil is essential for good combustion and low combustion gas emissions. prerequisite for stable atomising viscosity is that the oil temperature stays stable throughout the firing rate. Oilon L mass preheater keeps the oil temperature stable even if the incoming temperature fluctuates. On account of the construction and the electronic regulator, the temperature of the oil flowing to the nozzle remains stable. The burner may, depending on the capacity and model, have one or more -kw heater equipped with a safety device to guard against overheating. The electronic regulator has an integrated minimum temperature limiter as well; this prevents the burner from starting if the oil is too cold. 1 asonry figure ød1 ød 1 Gasket ounting panel 3 Ceramic wool or equivalent asonry ØD1 see burner dimension diagram ØD D1+0 mm L see burner dimension diagram L
