4ton h industrial straw steam boiler

In mid-June this year, Hebei Province issued a notice regarding the development of gas-fired boiler nitrogen oxides (referred to as NOx) governance, in order to further deepen the boiler pollution control, reduction of nitrogen oxide emissions, improving air quality, will gradually nitrogen oxides exceeded boiler discharged for investigation and control work, high nitrogen oxide emissions from the original (150mg / Nm3 or above) is reduced to 30mg / Nm3. City, Hebei Province is located in the Yili Dairy Co., Ltd. to respond positively to governance EPA gas boiler NOx reduction, and led the way, three of the company's existing 15 steam tons / hour (t / h) gas 4ton h industrial straw steam boilers for low-nitrogen emissions transformation.

Protection devices require oil-fired boiler and furnace operators furnace operation requirements in the previous article we said fuel boiler safety issues, is on this basis that we talked about the boiler room safety requirements, other than that it accident there and boiler protection requirements boiler operator requirements in order to build a secure environment. Oil-fired boiler protection device to claim 1, the 4ton h industrial straw steam boiler must have high reliability, low-low water level alarm and interlock protection, interlock and overpressure protection. 2, the hot water boiler must be over-temperature alarm device. 3, when the fuel pressure is below or above a predetermined range of values ​​can be automatically cut off the fuel supply. 4, when the blower off, shall be automatically cut off the fuel supply. 5, to be fitted reliable ignition and flame protection program control means. Oil-fired boiler operators claim 1, after the boiler operator training posts must, must hold pressure boiler fireman operating permit issued by the technical supervision departments to posts. 2, the operator must strictly comply with the system, they are not allowed to leave their posts during the shift. 3, forbidden to store inflammable and explosive materials near the equipment. 4, abnormal and deflagration burner ignition, should stop to check. After starting the burner, suddenly turn off, start again need to wait at least 20 seconds. Flameout operation must be shut down to find reasons not boot within 60 seconds. 5, the boiler room to keep clean, good ventilation, keep dry. 6, when the boiler is disabled, you must cut off the power and close the oil valve. These are the important requirement for us to build our oil-fired boiler safety environment we want to help.

Why no gas pressure hot water boiler for steam separator drum:? Since no gas pressure hot water boiler for steam separator drum, i.e. evaporating heating surface and a superheater, economizer, spaced no intermediate container, water heating surface of the heating, evaporation and superheating is no fixed boundary, but as the load fluctuation and the gas pressure hot water boiler operating conditions varies, often superheat temperature as the load changes while greater volatility. Gas pressure within the evaporator heating surface does not constitute a hot water boiler circulating the working fluid, and no water separation, so that when the working pressure increases, the density difference decreases soda, so that the supercritical pressure, the gas pressure hot water boiler capable of reliably jobs.

The type of fuel gas 4ton h industrial straw steam boiler heat exchanger which heat exchanger fuel gas steam boiler are the following:? 1, shell and tube heat exchanger, the most widely used, the advantages of low cost, stable, moderate efficiency, cold pressure difference on both sides can heat. The disadvantage is that bulky, heat exchange efficiency is better plate heat exchanger; 2, plate heat exchanger, used in the thermal type tube slightly inferior, but the application of more heat exchange in the chemical industry, the advantage of small size, heat transfer efficiency. The disadvantage is the high price, the hot and cold sides of the small pressure difference is required; 3, volume of heat exchanger, substantially replace the two heat exchangers, seldom used, only the individual engineers also use sepia heart. Cost and volume of the tubular flat; 4, floating coil heat exchanger, a tubular outer shape slightly larger than the column, consistent with the principles of heat transfer tube type, but the efficiency is higher than the column tube below the plate. Since the service life is inferior tubular, is also substantially free of the use of such a heat exchanger; 5, soda heater, because there is no heat exchange process, so called soda heater. The principle is to use direct steam heating the water, so this process is used under certain conditions, rarely applied to the "heat" process, widely used for slaughtering, bathing, winter construction industry.
