Third, do water quality management

Careful maintenance of the boiler operators will have to do from the outside in, water quality management is also an important step in the maintenance of low nitrogen gas boiler. If the boiler water concentration is too high, it will lead to false water level phenomenon, resulting in the boiler does not work. Therefore, operators also need to strengthen water quality management and take preventive measures, so it is more conducive to long-term maintenance of low nitrogen gas boiler.

Fangkuai Company has a fully-automatic PLC intelligent control system designed and developed by itself with complete intellectual property rights. It adopts a combination of mechatronic control equipment and a programmable logic controller (PLC). Take the advanced programmable logic controller (PLC) as the "central processing unit" of the control system. The control system is operated through the touch screen, which greatly improves the degree of automatic control and operation reliability of the american boiler and mechanical, and the operation is simpler and more intuitive.

Main steam american boiler and mechanical gas valve and other valves, and a predetermined baffle flue gas system 1 shall be clearly marked boiler tubes, valves and dampers marked name, number, and media flow direction switching direction, should the main regulator valve for opening degree indication. Valve, the shutter operating mechanism should be installed at a location convenient to operate. 2 main steam valve should be installed near the outlet of the drum (potshell) or the header of the superheater. Boiler unit consisting of machine, the main steam valve the inlet of the turbine can be installed. Main steam valve vertical shell boiler may be installed in the boiler room to facilitate local operations. On each boiler steam pipe with steam header pipe is connected, cutting two valves shall be installed, it should be equipped with a drain pipe and cutting the valve between the valve open to the atmosphere, an inside diameter not less than 18mm. 3 evaporation rated greater than or equal to 220t / h boiler to be provided to the remote air exhaust valve. Fractional economizer inlet 4 can not be fitted to the water supply pipe and the water supply valve shut-off valves. For unitary unit, not fitted with a check valve to a water tube boiler feed water. The inlet of the economizer and separable leading drum (potshell) are mounted to the water supply pipe should be cut off the water supply valve and check valve. 5 feed water shut-off valve should be mounted between the drum (boiler shell) (or economizer inlet header) and a water supply valve and the check valve immediately connected with the water supply. 6 in the rated evaporation 4t h boiler / automatic water regulator shall be installed, operated and easy to place in the installation manual means fireman who feedwater control. 7 rated steam pressure is greater than or equal to 3.8MPa boiler pipes should be urgently put in a minimum security indirect drum water level and normal water level, discharge pipes should be installed on the valve, once full of water occurs in order to promptly turn on the water. This valve must be turned off in the boiler running. 8 in the drum (potshell), superheater, reheater and economizer, etc. which could gather air should be fitted with an exhaust valve. Different operating pressure of the boiler 9 should have a separate steam pipes and water pipes, respectively. When employed as a main steam pipe, the steam pipe must have a higher pressure automatic decompression device, and a safety device that prevents the low-pressure side of the overpressure (check valve). When the water pressure which does not exceed the maximum working pressure of 20% of the total water supply can feed water to the boiler system. 10 boiler feedwater system should ensure safe and reliable water supply. Boiler room should have an alternate water supply equipment. And the number of spare capacity and a water supply device is arranged water supply system, is determined by the design of the boiler room units according to the design specifications. 11 rated greater than or equal to evaporation 1t / h boiler water sampling device should pot, when steam quality requirements, there should be vapor sampling means. Sampling means and the sampling point location should be taken to ensure that water vapor representative sample.

Heat works Henan Henan gas american boiler and mechanical gas boiler with natural gas, liquefied petroleum gas, fuel gas such as city gas as fuel, gas boiler in Henan put out burning furnace, heating pot of water, and it vaporized into steam heat conversion equipment. Water pan (drum) is continuously released from the combustion of a gaseous fuel energy to heat the furnace, raising the temperature and generating steam under pressure, since the boiling point of water with elevated pressure is raised, Henan gas boiler is sealed, water vapor inside the expansion pressure is generated is limited thermodynamic form (strictly speaking, Henan steam gas boiler drum water is heated to the constant-pressure saturated water is then vaporized form) it is widely used as an energy source. Henan gas boiler and boiler shell consists of two main furnace and ensure accessories, ancillary equipment instrumentation, control and protection system safe and economic operation of its continuous constituted. Henan gas 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.
