With the rapid construction of the energy saving and environment-friendly society, the environment protection awareness become more and more penetrated into various industries. The energy saving matter of the horizontal boiler which offer heat power for industrial production also draw the government’s attention.
Industrial causes of too high alkalinity of boiler waters is a major driving force for social development, but also brought great pressure on the environment. Whether coal-fired boilers, biomass boilers, or, when the supply of energy, the emission of pollutants will soot and nitrogen oxides. Some enterprises in order to save costs, the pursuit of more profits, but also allowed to change the fuel, biomass boilers burning coal steal, wood, and even garbage doping or other industrial waste, produce dioxins and other carcinogens directly into the atmosphere after combustion, pushing PM2.5 concentrations.
Since started Blue Sky Battle horn Guangdong Province, many cities have begun to respond positively, Dongguan City, is one of them. Atmospheric do in-depth business thoroughly, and the development of industrial boilers business accounting, confirming the city's need to eliminate highly polluting boilers have 765 units, of which 728 sets of biomass boilers, 37 coal-fired boilers. Subsequently, promote the transformation of facilities operations out of high pollution boilers within the city.
As of May 14, 2019, the city's 324 enterprises active removal of 363 coal-fired boilers burning biomass, as well as 83 to 84 companies demolition of the old boiler pipes, 447 completed phase-out plan of the boiler in advance.
Although there are many companies take the initiative to carry the main responsibility for the ecological environment, but there are still some chances enterprise.
Atmospheric Office official admitted that "in the daily inspection, the company found that some still illegal use of boilers, perfunctory 'coal to gas' work." Among them, although some enterprises written off coal, biomass fired boilers, but because of natural gas boiler installation behind schedule, forced production needs, but to let the old boiler continues posts. There are companies more "capricious", install two-way pipeline for new and old boilers, strict supervision when using gas-fired, law enforcement officers continue to take a coal burning biomass. There are even companies deliberately delayed "from coal to gas," progress, choose to enable the original write-off of the boiler.
This year, the Office of Atmospheric inspection personnel to go to 244 companies in the field to check the boiler usage, found that 42 enterprises there is illegal use of boiler problems. Among them, there are 18 companies of illegal use of biomass boilers has been canceled. "Not only pollute the atmosphere, there are still significant safety risks." Atmospheric Office inspection personnel Lurui Quan said, "the city's coal-fired, burning biomass boilers as well as 113 units, involving 94 companies, is expected to complete phase-out year, access to clean energy. "simple behind the data, there is a thick ledger out of the transformation of the boiler," when removed, when write-off, out of a pin number one glance. "
Atmospheric Office official also said the recent city towns Street (Park) Atmospheric Office will carry out investigation and remediation special action has been canceled boiler, supervise and guide enterprises to demolish the old boilers and pipes, put an end to "note not sell" phenomenon. At the same time, urge enterprises will have been dismantled boiler dedicated to the sale of scrap recycling company, effective way to solve the old boiler, complete eradication of pollution and safety hazards.
The kind of winter heating causes of too high alkalinity of boiler water heating boiler with a number of related questions: boiler, which in the winter, heating is carried out, it will be used mainly to a heating boiler This, then, is quite good with hot water boiler steam boiler? And, on the boiler, what difficult problems need to be solved? These issues are on the boiler, and also we need to know, so the following immediately to give a specific answer, so that we learn through to clear. 1. In the winter heating boiler heating, hot water boiler is relatively good, or steam boiler is better? This, then, appears in the box boiler, hot water boiler should be better, the specific reasons for it, is as follows: If a steam boiler, then, but also the hot steam into hot water, so in order to carry out heating.

Alkalinity is a measurement of how much a given water sample can resist the pH-dropping effects of acid. This relates closely to the water's hardness and calcium ion levels, which measure the concentrations of various minerals dissolved in the water, since these minerals buffer the water.Get A Quote
Alkalinity is the measurement of how basic or alkaline water is. Water with a pH greater than 7 is alkaline, as opposed to acidic. Every species of fish has adapted to a specific set of water conditions, including pH. Keeping a fish in the wrong pH can stress and kill it.Get A Quote
boiler water alkalinities rise above the recommended maximum, reduce the feed of alkali bearing materials or reduce the total alkalinity of the treated water if a softener is used. In an emergency, increase the blow down rate if necessary to bring boiler water alkalinity under control.Get A Quote
In boiler systems, corrosion resulting from carbon dioxide is most often encountered in the condensate system. Because feed water deaeration normally removes carbon dioxide from the boiler feed water, the presence of the gas in condensate is typically due to carbonate and bicarbonate decomposition under boiler conditions.Get A Quote
Jun 24, 2014 · That oxygen comes out of solution as the water boils, and it can eat holes in the boiler, right at the boilers waterline. If you decide to feed with hot water instead of cold water, the minerals in the water will come out of solution on the automatic water-feeders seat, and that can cause a flood, especially if its a one-pipe-steam system.Get A Quote
Testing Alkalinity In Boiler Water. Alkalinity is a key control parameter for boilers (outside of the prescribed operating range, it can lead to corrosion, caustic metal embrittlement, and carryover) and cooling water systems (where it has a significant effect on chemical treatments for scale and corrosion inhibition).Get A Quote
Apr 25, 2017 · High conductivity is related to high TDS (total dissolved solids) concentration in water, amount of dissolved mineral salts in water. Conductivity meters that measure conductivity also aim to measure the TDS of the sample for producing the result. For reducing the TDS of water on a domestic or an industrial level, you must seek help from an expert.Get A Quote
Alkalinity is a total measure of the substances in water that have "acid-neutralizing" ability. Alkalinity indicates a solution's power to react with acid and "buffer" its pH --that is, the power to keep its pH from changing. So while pH measures the strength of an acid (base), alkalinity measures the ability to neutralize acid (base).Get A Quote
Boiler Water Conductivity Measurement Fundamentals. As a boiler generates steam, any impurities which are in the boiler feedwater and which do not boil off with the steam will concentrate in the boiler water. Inside the boiler the heat generates steam bubbles inside the water.Get A Quote

Mar 18, 2016 · You have this problem if: Your water heater T&P valve keeps opening to release water. Also, if the T&P valve goes bad/starts leaking (which it will eventually), then pressure will continue to build in the tank, leading to a burst or explosion. How to prevent: Pressure builds in the tank when you set the temperature too high (140-145 degrees).Get A Quote
