Recently, Tianjin issued a notice to expand the scope of the ban on high-pollution fuel combustion zone, which is based on high-pollution fuel combustion zone ban on the delineation of Tianjin in 2015, to further expand this range, Tianjin has completed the bulk of urban and rural coal clean energy alternative areas have been completed and no did not go to the construction of Wuqing classified as high-pollution fuel combustion zone ban, and to delineate new range of units street town combustion zone ban.

1, the implementation of zoning classification control. Still requires strict control within the range 2015 designated combustion zone ban, prohibited the use of a single steam of less than 35 t / h of coal-fired boiler, steam 35 tons / hr or higher requires a particularly coal-fired boiler for emission limits or ultra-low emission requirements, while a total ban on all kinds of loose coal burning.

2, ban on burning area has expanded. New ban on burning area of ​​3107.99 square kilometers, Binhai New Area and design Dongli, Xiqing, Jinnan, Beichen, Wuqing, Baodi, Ninghe 9 district and Haihe Education Park. After the adjustment, the city's high-pollution fuel combustion zone ban area of ​​830.54 square kilometers by 2015 increased to 3938.53 square kilometers, accounting for 33.05 percent of the city's total area.

3, clearly biomass fuel control requirements. According to local emission standards biomass fired boiler air pollutants Tianjin promulgated in 2018, re-notice provisions of the central city, Binhai New Area, the seat of government of other towns and other key areas of government regulations prohibit burning biomass briquettes .

Boiler energy efficiency testing to detect what are: industry hot water atmospheric boiler energy efficiency testing, both for boiler manufacturers, boiler or customers, are very important testing authority. First of all, it is the assessment of the boiler manufacturers to test whether the performance of the products guarantee value. Then, it is clear the main factors affecting the energy efficiency of the test results and the analysis of influencing factors, manufacturers may have to adjust the targeted short term, making products more efficient and safe. These adjust the final beneficiary who is a client application, because the boiler thermal efficiency of the boiler test content directly affect energy consumption, related to the interests of customers. The main contents of the boiler efficiency testing 1, the boiler thermal efficiency test: a) evaporation boiler assay; b) the excess air ratio boiler detection; c) exhaust gas temperature detection; D) of the fuel combustion efficiency test; E) the thermal efficiency of the boiler test; F) fuel consumption; G) than gasoline, kerosene and the like. 2, a new boiler product energy efficiency testing: whether the determination of the thermal performance of the boiler as designed to determine the operating mode of the device. The boiler evaporation, thermal efficiency, combustion efficiency, the heat loss and the like. 3, boiler operation adjustment test: to determine the most economical boiler operation mode to identify deficiencies in the operation of the boiler. The maximum boiler load, the minimum load of the boiler, fuel requirements, economic load, exhaust gas temperature and reasonable, the best air-coal ratio, the excess air ratio, the ratio of secondary air and the like. 4, before and after thermal performance comparison test boiler: evaporation variation, the influence of combustion, thermal efficiency of the boiler and the like. 5, fuel industry analysis, elemental analysis: determination of coal, oil, gas and other fuel quality, ease of controlling the fuel into the plant enterprise quality. 6, water quality testing, scale-like: Water quality is determined, the control indicators boiler water to prevent boiler scaling.

4 tons steam industry hot water atmospheric boiler fast boiler's Henan small series with you briefly quick 4 tons a steam boiler. Water in the steam drum is heated to become vapor, fire emits heat in the furnace, it is the principle of a steam boiler. He said first boiler say "pot." This boiler is a boiler drum with a water cooling wall at about the subregional arrangements drum pyrotechnic two return pipe, before the folded portion of the drum front smoke box. Between the drum and the tank in connection with the downcomer tubes and water-cooled bi, constituting the frame of the combustion chamber. There upper steam separator drum to reduce the water vapor out of the tape. Pan heating surface of a lower portion of the drum, and the water cooling pipe bi pyrotechnic tube. A chain grate combustion section and drive means, coupled with the combustion chamber pan rack on the frame configuration composed of the grate. Four weeks envelope refractories. . From coal fired into the hopper, the shutter coal front portion while sealing air control seam thickness. Blast into the lower part of the combustion chamber is a place that boiler greater resistance, need to force the blast. Cinder burn out, the rear portion of the grate by the "beak iron" discharged from the slag out of the furnace feeding machine. The boiler flue gas from the rear, by the front drum smoke tube a return line, the return from the two rear return smoke tube, and then into the dust separating ashes, and then discharged through the chimney draft fan. Not only is the induced draft fan exhaust fumes, the negative pressure of the boiler operation is required. Steam boiler pressure vessel, the safety device is necessary. Boiler necessary water level gauge, pressure gauge, safety valve, thermometer, and under the pressure of the electric pump can pay, and the vapor pump when power is off can also be used.
