The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.
The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.

PARAT Halvorsen AS has now added up to 600kW Electrical Elements to our popular Combined Boiler. This will give the vessel the option to run the boiler for steam
Low nitrogen oils can contain up to 15-20 times less fuel-bound nitrogen than standard No. 2 oil (less than 0.001% fuel-bound nitrogen). When low NOx oil is fired in firetube boilers utilizing flue gas recirculation, NOx reductions of 60%-70% over NOx emissions from standard No. 2 …
combined vertical exhaust gas and oil fired boiler The special spherical shape of the furnace top plate gives an increased stability against ship vibrations and protects this part of the boiler against partial overheating, because residues in the boiler water are led to the boiler bottom before they can accumulate on the furnace top plate.
• The NH199-DV/ NH150-DV is a boiler to be used for space heating or indirect water heating only. Do not use the hot water supplied by the boiler for drinking purposes. • This boiler has a pressure rating of up to 150 psi, but it is designed to be used in a low pres-sure (15 psi) closed loop heating system. Use a …
steam coasting for boiler agent. The Separation of Oil from Exhaust Steam and Boiler Feed Water. the oil in the form of a spray so that the steam carries it to the It is stated that a coating of grease of water, or a boiler water conditioning agent, such as.
In a coal-fired boiler, a heat recovery unit is located upstream of a dry electrostatic precipitator so as to reduce the temperature of exhaust gas flowing to the dry electrostatic precipitator and thus prevent reverse ionization in the electrostatic precipitator. The heat recovery unit located upstream of the dry electrostatic precipitator will in no way be corroded even if the concentration

In the 1960s, the number of boilers for shipyards around Europe increases. During this decade, the unique combined oil and exhaust gas boiler is designed and introduced to the market. In 1998, the first large oil-fired boiler MISSION OL is delivered. The boiler is a result of the best technology from Sunrod and Aalborg Industries. 1919 1960s
Exhaust Gas Boilers also known as Exhaust Gas Economizers, with extended heating surface, used for waste heat recovery in motor ships. A diesel engine loses approximately 30% of the energy to the exhaust gases. A turbocharger recover some of it, but there is still heat losses that can be recovered by means of an Exhaust Gas Boiler…
This technology involves the injection of the reducing agent into the boiler exhaust gas in the presence of a catalyst. The catalyst allows the reducing agent to operate at lower exhaust temperatures than NSCR, in the 500 to 1,200° F depending on the type of catalyst. NO x …
Mar 01, 2015 · 2.2. Novelty of OPSB-A and OPSB-C. The option B drying agent has been adopted in our previous work to demonstrate the merits of an OPSB process. However, compared with the conventional two-component (hot flue gas and hot air) drying agent used by a direct-fired fan milling system, using the option B drying agent increases the flow of the hot flue gas extracted from furnace outlet because it
Guide to Low-Emission Boiler and Combustion Equipment Selection C. B. Oland. DOCUMENT AVAILABILITY Reports produced after January 1, 1996, are generally available free via the 6.6 Emission control options for natural-gas-fired watertube and firetube boilers.. 6-12 6.7 Emission control options for biomass-fired, stoker-fed, watertube
This means that Exhaust Gas Boilers shall not be designed to reduce the gas temperature at the EGB outlet below 170-180°C at Continuous Service Rating. Besides, at gas temperatures below 170-180°C, the vaporized unburned oil particles in the gas condense to an adhesive mixture of soot and oil resulting in troublesome deposits on the tubes and on the heating surface of the Exhaust Gas Boilers .

The Condair GS offers steam humidification with low operating costs. The economy of using gas makes this humidifier around 60% cheaper to power than an equivalent electric steam humidifier. This gas-fired humidifier incorporates ultra efficient condensing technology. Heat is recovered from the exhaust flue gases and used to pre-heat the
The vent line connection on the gas pressure regulator and the low and high gas pressure switches must be piped to outdoor air by installer in accordance with the National Fuel Gas Code, ANSI Z223- 1-1991 or latest addenda. In Canada gas installations must be in accordance with the current CAN/CGA B149.1 and .2 and/or local codes.
- The gas temperature outlet in an exhaust gas heat exchanger is kept above 180°C to prevent low temperature corrosion occurring. There is about 10% water vapour in exhaust gas and also sulphur products and this can lead to suphuric acid forming which has a …

The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas. When firing natural gas, other losses such as dry gas loss, moisture in fuel and
