20t Boiler Brand Seller Kazakhstan

Let's look at the causes of hot water 20t boiler brand seller kazakhstan corrosion it.

1, does not control the supply of water, a 2.8MW hot water boiler, pay hundreds of tons per day, but more often, do not need to make up so much water.

2, not to seriously implement the "low-pressure boiler water quality standards", the standard clearly states, when the water temperature is ≤95 ℃, circulating water should be controlled PH value of 10-12, which is a very important indicator, but some units do not be error is supplied by the hot water boiler steam boiler water standards.

3, the hot wire mounting network failure, the user can not send the circulating water system ends. Increasing the number of exhaust air, heat will drain, not exclusively to cool, resulting in an increase of the amount of leakage.

4, may also be a constant pressure expansion tank and the boiler inconsistent. Height of less than 15 meters, but the boiler constant pressure to 2.5kg / cm2, fireman to maintain 2.5kg / cm2 working pressure indicators, regular pay, for no apparent reason the water overflows into the ditch, the water was wasted .

1. The concept of absorption of heat absorption systems using flue gas heat exchanger is used to recover waste heat of flue gas in the gas 20t boiler brand seller kazakhstan, the process shown in Figure 1. In additional gas absorption heat pump with the boiler flue gas condensation heat exchanger, an absorption heat pump with natural gas as driving power, the occurrence of cold medium, the medium is cooled in the flue gas in the flue gas condensing heat exchanger, heat transfer process can used direct touch touch-type heat exchanger may direct the exhaust gas temperature in the system drops below the dew point, condensation of water vapor in the flue gas heat to reach the intent of flue gas heat recovery and water. Heat supply network backwater into the primary absorption heat pump is heated, and then into the gas boiler is heated to a temperature of planning to give out, the end of the heating process water heating network. Exhaust gas boiler into the bottom of the chimney, the draft fan is placed on top of flue gas condensation heat is withdrawn and mixed into the flue gas absorption heat pump of flue gas condensation heat exchanger, the system exhaust temperature drops to 30 ℃ vented to the atmosphere into the chimney after less. Out of the chimney flue gas between flue gas and returned to port additional partitions. Our test systems selected direct touch-type touch flue gas condensation heat exchanger. This allows the system to use the skills heating power (system for low level heat than the heat input in the system of gas) progress more than l0%. The skills currently in Beijing General Logistics Department has recovered waste heat boiler room engineering, Beijing bamboo plant to recover waste heat boiler used in the project, to obtain a better energy-saving effect. Such incremental contribution skills (including contribution absorption heat pump, heat exchanger and flue gas condensation supporting pumps, valves and other equipment) generally less able to recover 3a.

2. Mechanism smoke condensate purification of exhaust smoke condensate component of the purification of exhaust components is messy heat and mass transfer process. Condensing the flue gas is flue gas water vapor condenses on the heat exchanger wall or film into fine droplets, and large water drops or fine and then converging streams. In this process, the flue gas condense different components will be dissolved in an aqueous solution, an aqueous solution of the condensation reaction may occur in the flue gas to remove harmful substances such harmful exhaust gas content decreased. NOx in the flue gas purification process condensate: there are nitrogen oxides NO, NO2, N2O, N2O5 etc., a general term NOx. The primary material constituting the atmospheric pollution and photochemical smog is NO, NO2, other ignored. Nitrogen oxides in the boiler flue gas first is NO, and NO2 content less. NO slightly soluble in water, the dissolved amount is negligible. NO2 soluble in water to form aqueous nitric acid and nitrous acid. NO2 is a water-soluble reaction formula: 2NO2 + H2O9HNO3 + HNO2.

To protect the economic development of enterprises, production safety running smoothly, according to Qingyang County in Anhui Chizhou municipal government air pollution control requirements, coal-fired 20t boiler brand seller kazakhstan inspection pull the plug on a regular basis in October 2018.

Qingyang County Market Supervisory Authority for the county a number of companies were visited research to understand the company's current production operating conditions and problems, start from regulatory functions, for enterprise development to provide quality services, reduce business costs.

Special equipment boiler pressure is high risk, than a regular inspection cycle must immediately stop using, but they are also necessary for the production of business equipment, once the shutdown enterprises will face shutdown. Looking at business owners anxious eyes and counties actively discussing with the city center expert special inspection, and according to regulations, to quickly determine a set of effective programs and promptly inform each enterprise.

Through contact with the surrounding counties and cities to understand the relevant units of the boiler fuel change fees and counties take the initiative and boiler companies approached agreed upon with the use of rehabilitation programs, a significant reduction in transformation costs. Up to now, Qingyang County has completed 12 boiler fuel change work, the cumulative cost of more than 60 million.

Second, premix condensing 20t boiler brand seller kazakhstan, that is, many professionals say the real condensation. This boiler design depth total condensation on the use of the early art, can achieve high thermal efficiency of 108%; With frequency premix combustion technology, energy than conventional gas boiler 40% of nitrogen oxide emissions below 30 mg / cubic, energy saving effect is very obvious. These advanced technologies make the first premix condensing boiler is higher than a lot of false condensing boiler, it takes about one year to recover the cost of investment and more.
