We learned from Zhenjiang Municipal Environmental Protection Bureau, to further promote the Battle of Blue Sky, enhance air quality, the city actively carry out biomass heat exchanger and boiler in ethiopia investigation and remediation work has been completed seven bathrooms demolition of straw biomass boiler work in built-up urban area .
Biomass boiler pollution remediation has been a major focus of air pollution control, some of the city bathhouses, hotels, restaurants in the use of raw materials process boilers, illegally blended with coal, waste wood, waste and other substances, not advanced treatment of smoke, nitrogen oxides and other pollutants directly into the atmosphere, some impact on air quality.
According to relevant regulations, Zhenjiang city, the city built the region prohibited the use of straw biomass boilers, the current investigation and the bathroom were 10 straw biomass boiler, in which 7 have been removed, two shutdown ready transformation. At the same time, straw biomass boiler outside the urban area will be completed before the end of June classification renovation work, all dedicated boiler using biomass briquette students, prohibit blended with other fuels, coal, wood, etc., and must complete the construction of the bag efficient dust embodiments, emissions guarantee compliance.
(3) selective non-catalytic reduction (SNCR, Selective Non-Catalytic Reduction), is mainly used for waste incineration plants and other medium and small heat exchanger and boiler in ethiopias, mature technology, but its efficiency is lower than the SCR method; small investment, short construction period.
With respect to coal-fired boilers, the fuel gas boiler are environmentally friendly products, polluting combustion gases is greatly reduced, but each boiler manufacturers have energy efficiency is not the same, Henan Granville boiler fuel gas boiler radiation heating surface is full corrugated furnace, convection heating surface using threaded pipe, heating surface, producing enough heat boiler output, thermal efficiency can be up to 92%, higher than the state.
Boiler water level adjustment method to adjust the heat exchanger and boiler in ethiopia normal operation of the boiler water level to maintain steady drum level, should do the following: (1) to control the water level, water level must be carefully monitored, in principle, subject to a water level gauge to electrical contacts to monitor water level for the main meter. To maintain the water level in place clear and accurate. If the water level gauge mica or no rocked slightly unclear, flush water level indicator, each control level gauge regularly and accurately determine the change in water level the boiler. (2) at any time to monitor steam flow, water flow, pressure and water pressure drum major data found is not normal, immediately identify the reasons for timely processing. (3) If the water level more than ten 50mm, should adjust the door off a small water supply, reduce the amount of water, if it continues to rise to + 75 mm, should open the door turn on the water drainage accident to the normal water level, and investigate the cause. (4) water level is below normal operation -50mm, it is timely to open a large door increases the amount of water to adjust the water supply, the water level back to normal as quickly as possible, and to identify the reasons for timely treatment. (5) lifting the load unit, to start and stop the pump, high pressure heater or splitting, boiler blowdown periodically to empty or exhaust steam safety valve operating and accident conditions, respond to changes that occur ahead of drum water level is adjusted.

Jul 14, 2003 · There is only one boiler. The one boiler has a pipe or tubing that goes through the upper and lower, sometimes only upper, and sometimes only lower, parts of the boiler. This pipe or tubing is the heat exchanger. Boilers that have heat exchangers also have water level regulators that are connected to the water level sensor in the boiler.Get A Quote
The heat exchanger will control the heating of the components and will participate in several phases during the components cooling by which the paper pulp is produced. For this reason, this heat exchanger will have a height of 16 meters and a diameter of 3.8 meters, offering a total area of about 6500 m2. Its curb weight will range 65 tons.Get A Quote
Heat exchangers allow heat to flow through a material, generally a copper tube or stainless steel plate, from the hot side to the cool side. Scale or any other material that accumulates on the heat exchange surface acts as an insulator and reduces the efficiency of the heat exchanger. Most heat exchangers are designed to operate at a specific temperature range called DT.Get A Quote
Causes of a Cracked Heat Exchanger. Now that weve covered some common symptoms concerning a heat exchanger with a crack in it, lets get into some of the likely causes. Dirty Air Filter: The most preventative and cheapest to avoid cause of a cracked heat exchanger is a dirty air filter. A dirty or clogged air filter hinders the air flow within the furnace during the heating process.Get A Quote

In a brazed plate heat exchanger all the plates are brazed together (normally using copper or nickel) in a vacuum furnace. It is a development of the gasketed plate heat exchanger, and was developed to provide more resistance to higher pressures and temperatures at a relatively low cost.Get A Quote
Dec 06, 2015 · Ive fitted ball valves of the flow and returns at the top of the boiler to help purge air though the heat exchanger. The air is being purged successfully and the boiler ran fine for a few hours but now back to square one.Get A Quote
The heat exchanger transfers the heat from the exhaust gas to a liquid (water or water-glycol solutions). When heated up, this liquid can be used in central heating systems; for preheating air in the combustion chambers of furnaces and turbines; to dry coal, pulp, wood and other materials as well as for generating electricity with a RankineGet A Quote
