Boiler energy efficiency testing to detect what are: 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.

The fuel can be natural gas boiler into gas-fired, city gas boiler, boiler coke oven gas, liquefied petroleum gas boilers and boiler; functions can be divided in accordance with KS-Q water natural gas boiler, CLHS / CWNS natural gas low price central heating hot water boiler for hotel (including natural gas heating boilers and gas boilers bath), LHS / WNS natural gas and steam boiler; can be configured in accordance with natural gas boiler is divided into vertical and horizontal natural gas boiler; flue gas flow can be divided according to a single backhaul gas three-pass boilers and natural gas boilers. Fuel oil-fired boiler is the difference between a fuel (such as diesel, oil, kerosene, etc.), natural gas boiler fuel is natural gas (such as natural gas, city gas, biogas as well as liquefied petroleum gas, etc.), depending on what fuel boiler combustion devices called burner, natural gas burner configuration called boiler natural gas boiler, oil boiler burner configuration called oil-fired boiler, oil-fired boiler and the difference between natural gas boiler that what fuel burners.

4 tons steam 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.
