Lng Fired Hot Water Boiler

What is LNG – Liquefied Natural Gas?

LNG – liquefied natural gas – is methane (CH4) that is liquefied by chilling below -161°C. This the same natural gas that is piped to homes and businesses. As liquid, the volume of LNG reduce to 1/600 its gaseous state. This makes LNG transportable in cryogenic ships or trucks. After regasification, it reverts to and is used as natural gas.

LNG Fired Hot Water Boilers

Industrial and commercial boilers are one of the most common uses for LNG. LNG as an alternative fuel to diesel .The industries include dairy products, manaufacturing, food processing and construction products.
LPG can be in liquid form at a relatively low pressure of 2 to 5 bar at atmospheric temperature. This makes it convenient to handle in small cylinders. This coupled with the high heating value has made it the most popular household cooking gas in most of the third world countries. Governments subsidize LPG for domestic use, which makes it costly for other uses.
In the global boiler market, lng fired boiler is always taking the leading role. Clean combustion, high efficiency and energy saving are the main features, besides, there are some specific advantages that people choose lng fuel boilers.

Lng fired hot water boiler advantages:
1. lng boilers do not need fuel storage equipment: lng fired boiler for sale in the industrial market using pipeline transporting gas as fuel, don’t need fuel storage devices.Before supply incineration is also does not need fuel preparation equipment, processing, thus greatly simplify the system saves fuel storage fee.
2. Because the lng fired boiler heating surface does not exist problems such as pollution, slagging, wear, so people can choose high smoke speed, reduce the scale of the convection heating surface. Placed properly convection control, so that the lng boiler with a capacity of coal-fired boiler layout is compact, light weight, small scale, equipment investment significantly reduced.
3. Low cost of auxiliary equipment. lng fired boilers do not need auxiliary equipment, such as dust collector, slag equipment and fuel belongs to equipment such as drying apparatus, thus greatly save the auxiliary investment costs, it is also a big show of saving energy.

lng hot water boiler design  structure:

1.Designed with three passes, all-wet back structure.
2.Fire tubes are surrounded by water, and these design making efficience up to 90%.
3.Threaded tube: Strengthen the heat transfer, increase the gas hot water boiler heat efficiency
4.Big combustion room design: increase furnace heating area, decrease gas boiler size, and reduce the emission of the Nox Corrugated hearth make the boiler safer.

5.Equipped with computer manpower controller, operating easily, easy management, reliable operation, completed security protection function; With the function of protection of water shortage, heat preservation, overpressure, selfchecking of  breakdown, burner fault flameout, alarmming etc. chain safeguard function; Having  the function of selfcontrolling between strong and weak fire. And also the function of recording on burning work time. setting freely of the temperature control.

6.Selecting the world famous brand burner, excellent quality, advanced technology, sufficient burning, reliable operation; Having the function of furnace cleaning, automatic ignition, ignition detection, high voltage protection of gas firing, low voltage protection of gas firing, leak detection, etc. to ensure the safe operation.

 7.The cylindrical appearance, small area occupied; Adopting color plate for the outer packing, elegant appearance of the externality; adopting high thermal resistance material for the thermal insulation layer. heat preservation effect is good.

8. Adoption of high-effective hat exchange tubes, together with reasonable flow velocity of smoke and gas, makes thermal efficiency of boilers 6%-8% higher than national standards

9. With the help of inertia separation of smoke and dust in boilers, together with complementary high-effective multi tube dust cleaners, the concentration of dust discharge from boilers is within the requirements on class I of environmental protection.
