Boiler, fuel combustion, emissions will inevitably occur. Our country attaches great importance to air emissions of pollutants, environmental policy after another, contaminants in the boiler selection, must be produced as a criterion of choice. Therefore, enterprises in the choice of heating boilers, to be issued in accordance with local air pollution emissions requirements, select the appropriate boiler products.

4 tph WNS condensing steam boiler project for paper industryIn the corrugated paper processing line of the packaging industry, the steam boiler is an important heating system for increasing the temperature of the paperboard and is one of the essential equipment. Founded in 1995, Fuijian Nanan Lianfa Paper Industry Co., LTD. attached great importance to technical input and strictly controlled product quality. At the same time, they knowed thoroughly that the efficiency of boiler operation would directly affect the company's product quality and economic benefits. With the fierce market competition, Lianfa Paper decided to eliminate backward production capacity and introduce high-quality and high-performance environmentally friendly gas-fired steam boilers.After comparative analysis of many boiler products, Lianfa Paper was attracted by the excellent quality performance and environmental advantages of ZOZEN WNS series gas-fired boilers. All longitudinal and circumferential seam welding adopts advanced submerged arc automatic welding technology and passes 100% radiographic inspection to prevent unqualified welds. The design of the large-diameter corrugated furnace of this series of boilers provides sufficient heating surface and steam storage space to ensure the stable and high efficient output of high-quality steam. With the energy-saving equipment installed at tail flue, the exhaust gas temperature can be reduced to 60℃. The thermal efficiency is up to 98%, and the ultra-low emission of nitrogen oxides can be easily realized, and the economic benefits as well as the environmental benefits can be improved.
At its core, an expansion tank is there to absorb water and backwards pressure. So, in some cases depending on the root cause it may improve water hammer. Owning a water heater is a necessity, but thermal expansion adds pressure to the tank and your system.Online chat

The size of the expansion tank is based on the TOTAL volume of water in the whole system and the operating temperature. Radiators hold a lot of water and I suspect when that water heats up, it expands too much for a #30 tank.Online chat
Expansion Tanks When water is heated, it expands due to a phenomenon known as thermal expansion. Expansion tanks are designed to safely absorb the excess water created and prevent relief valves from triggering.Online chat
Expansion tanks are required in heating, cooling or air condition system to avoid unacceptable increases of system pressures when water expands during heat-up. Explosive Power of Super-heated Water 1 lb (0.45 kg) of nitroglycerin > 2 000 000 ft lb f (2 700 000 J) 1 lb (0.45 kg) of water flashed into steam > 750 000 ft lb f (100 000 J)Online chat
The expansion tanks purpose is to protect your houses hot water system from excessive pressure, which can cause damage to fixtures, your water heater, lines, and/or fittings. Inside, the tank has a rubber diaphragm at around the mid-point of the tank; pressurized air goes below the diaphragm in the bottom half of the tank, and water flows in and out of the top half of the tank.Online chat
Sizing water heater expansion tanks is easy for your hot water heater, and adding a hot water expansion tank can be done within 30 minutes. Water heaters can be fitted with expansion tanks to capture expanded water and prevent water heater malfunction.Online chat
Jun 21, 2016 · The expansion tank gives the excess hot water a place to flow into, eliminating unnecessary stress on your hot water heater and saving you from inconsistent hot water pressure. Signs that You Need a Water Heater Expansion Tank If you have a closed system. If you have a pressure regulating valve or a check valve.Online chat
Size matters when it comes to your tankless water heater. In fact, it is the most important part of choosing a new unit for your home. Having a water heater that is too small will result in it not being able to produce enough hot water for your household demand.Online chat

Expansion tanks are normally installed above the water heater on the cold water line before it enters the water heater; however, they can really be installed anywhere on the cold water line prior to entry into the water heater. Having an expansion tank helps prevent dripping faucets and running toilets by keeping the extra built-up pressure in the system from reaching the fixtures and prematurely damaging them.Online chat
The tanks are designed to absorb the expansion forces of heating or cooling system water to maintain the proper system pres-surization. Expanded water, resulting from increased temperature, is stored in the expansion tank during peri-ods of high temperatures and returned to the system when the water temperature is lower. The tank must beOnline chat
Most expansion tanks come pressurized to 12 40 psi, but before you install the tank you have to match the system pressure. Start by removing the protective cover from the air valve on the tank. Use a tire gauge to check the pressure. Use a bicycle pump, or compressor, to fill the tank to match the system pressure you noted earlier.Online chat
An expansion tank prevents pressure increases due to thermal expansion of your water. As your water is heated from 50° F to 120° F, it expands by approximately 2%. If you have a closed system, which means there is a backflow preventer or other device that prevents your water from flowing back into the water main, thermal expansion will cause very rapid pressure increases in your plumbing system.Online chat
