vertical oil or gas fired hot water boiler

What safety matters should be noticed in the operation of industrial boilers?

Industrial boiler is a kind of equipment which must be used by many manufacturing enterprises. It can provide sufficient thermal energy for the production of enterprises so as to ensure that the production can be carried out in an orderly manner. However, because the industrial boiler is dangerous when it is used, the workers who operate it must pay attention to the following items in their daily work in order to better prevent the occurrence of safety accidents. So what safety matters should be noticed in the operation of industrial boilers?

1. Industrial boilers should check the inlet and outlet valves of their gas meters and the main valves in front of the furnace before using them, and close them when the pipes are replaced. When opening the furnace door, we should pay attention to check the situation in the furnace, especially pay attention to the phenomenon of gas leakage, if the leakage is found, it cannot be ignited, but it should be checked and repaired in time to ensure the safety before ignition.

2, pay attention to check the flue of industrial boiler, can't have water or not and keep the flue open all the time. At the same time, no combustible and explosive products such as diesel oil, firecrackers and so on should be placed around the boiler, and safe passageways of sufficient area should be set aside.

3. Start the blower before igniting the industrial boiler and open the air valve on each burner. When igniting, we must pay attention to fire and so on. We must not put the cart before the horse in order to prevent explosion. Also note that the burner should be ignited and adjusted in sequence from top to bottom and from inside to outside.

4. When using industrial boilers, if the blower stops abruptly due to power outages and other reasons, all gas and air valves on the burner should be closed immediately and the furnace doors should be opened if necessary to prevent accidents.

5, the operating room should be equipped with a gas alarm, if found gas leakage of the county should close the indoor gas valve, and then find out the leak point and timely repair, in the course of its attention must not use open fire to detect leakage.

At the end of 2017, China Guodian is located in Jiangxi Province Wanan Hydropower Plant After evaluating the situation, some of the steam boiler used to purchase much-needed daily work. Sales Manager fast boiler combined with the actual situation of the power plant for its recommendation 2 0.5 tons of electrically heated steam boilers.

Method for safe operation of steam boilers steam boiler before use, must be checked for damage of the insulating layer, to check the burner is operating correctly, and to check the position of the opening degree of the valve to ensure it is correct. Electric heating boiler and the boiler is mainly composed of electric control box and control system. Its characteristics are environmentally friendly, clean, no pollution, no noise, automatic, with limited energy and reduce prices significantly, as a new boiler electric heating boiler equipment increasingly being recognized. Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage. There are heating and vertical oil or fired hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Must be checked for automatic control instruments and equipment safety equipment accessories, equipment, in order to comply with the requirements. Check item prior to ignition of the steam boiler: open valve before oil circulation pump, oil heating valve is opened, adjusted reasonably high level of the tank, the gas pressure is determined before the natural gas burner ignition must be within the range, the power good . Steam boiler furnaces operating point of the device first starts the circulation pump, the circulation pump outlet pressure, the furnace, the furnace pressure, and the system should ensure the return pressure in the normal range. Circulation pump run for 30 minutes before entering the next step, the system is stable. Open the gas tube steam boiler manual valve, button start-up burner, natural gas burner into the furnace, and then the ignition, the flame remains stable, i.e. is in a safe operating condition. In the firing process steam boiler, once the accident shut down the phenomenon occurs, the device automatically interlock the burner will be protected, should be promptly cut off the natural gas pipeline, furnace cleaning function should be started. Replace the rest of the gas stove, and stop cleaning. The system load requirements, temperature requirements and thermal oil outlet, the burner can automatically adjust the size of the fire source.

Xiao Bian now introduce gas steam boiler classification accuracy and precision hydraulic machine Henan fast boiler's steam boiler gas and hydraulic classification of a gas steam boiler By Type 1, an industrial gas steam boiler: heating and for industrial production and so on. Most of the parameters for the low, low capacity boilers, the fire bed combustion and thermal efficiency is relatively low. 2, power station boilers: mainly for power generation. Most high-parameter, large-capacity boiler, firebox and allow more efficient combustion. 3, the ship's boiler: a marine power. Such boilers generally low parameters, fuel oil, the requirements of small size, light weight, easy to move more. 4, locomotive boiler: The main use of locomotive power. Lower overall parameters are small capacity boilers, fire bed combustion, requires compact, movable. Two gas steam boiler in accordance with the kind of the working fluid and an output state classification can be divided into: 1, the steam boiler: the working fluid is steam outlet. 2, vertical oil or fired hot water boiler: hot water as the working fluid outlet. 3, special working fluid boiler: export of special working fluids, such as certain organic matter. Three outlet gas steam boiler in accordance with the pressure of the working medium can be divided into: 1, pressure boiler: the outlet steam pressure 14MPA (140kgf / cm). 2, high-pressure boiler: the outlet steam pressure 10MPA (100kgf / cm). 3, sub-pressure boiler: the working fluid outlet pressure of 2.5MPa. 4, pressure in the boiler: the outlet steam pressure of 3.9MPa (39kgf / cm). 5, supercritical pressure boiler: outlet steam pressure is about 25MPa (about 250kgf / cm). 6, subcritical pressure boiler: outlet steam pressure of 17MPa (170kgf / cm?). 7, low-pressure boiler: the outlet refrigerant pressure (gauge pressure) is less than or equal to 1.3MPa (13kgf / cm). Accuracy of the hydraulic machine, determines the precision of the parts. However, only static accuracy to measure the level of accuracy of press is not very accurate. This is because the size of the mechanical strength of the press itself has a great influence on the punching accuracy. If the strength of the press itself is low, the machine will be modified such that the pressure at the instant of Ao punching pressure is reached, so that, when the above-described conditions in a static tune even good, also since the strength of the deformation caused by the sample bed, differences occur. This indicates that the accuracy of the press and has a lot of strength, and the magnitude of the intensity of the work has a great influence on the press, so that high-precision parts and punched continuous strong cold stamping, the accuracy must be selected high, and the rigidity of the press.
