hot water boiler gas fuel oil fire tube
Gas-fired steam boiler three horizontal wet return back structure WNS series automatic oil, gas steam boiler three horizontal wet return back structure, improve the boiler operating environment, to improve boiler efficiency and service life; all of the flue gas channel is placed in water, the tail with the fin tube condenser and a sound production state designated boilers, pressure vessels manufacturers. Adhere to the people-oriented, science and technology a new development strategy, gathered from a high-quality management, technology, production and management personnel, and laid a solid foundation for the development of enterprises. On the basis of the traditional production based on coal-fired boilers, the establishment of an independent new product design, gas steam boiler using three horizontal wet return back junction have developed a new environmentally friendly coal vaporize boiler, electric boiler manufacturers construct WNS series of automatic oil, oil, electric steam boiler. Gas, electric heating steam boiler, electric heating oil furnace pressure hot water boiler fuel oil fire tube, organic heat carrier furnace, stove, second class pressure vessel 15 series, more than 200 standard models. \ Province Heng boiler, the boiler is the designated national R & D to improve the quality of our environment and the survival of boiler replacement products industry to make its due contribution to the provincial Heng Boiler Co., Ltd.
Classification accuracy of gas steam boiler and hydraulic machines with precision introduce gas steam boiler 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, hot water boiler fuel oil fire tube: 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.
Recently, Shaanxi Province issued a notice "issued four Battle 2019 program of work". Programs that: improve the mechanism of heating prices, heating prices reasonable development of clean, green electricity implement ultra-low emissions coal-fired power plants, a comprehensive clean canceled preferential tariff class of high energy-consuming industries unreasonable prices and other preferential policies. Off Area ban coal stove, substantially eliminated cogeneration heating pipe network coverage in the range of coal heated oven (furnace).
According to focus on the use of coal and clean use of principles, focusing on reduction of non-coal for electricity, increase the proportion of electricity from coal. Increase Condensing units and cogeneration units technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate coal-fired boilers and scattered inside the pipe network coverage. Actively implement alternative heat source, deadline for shutting down the Guanzhong area below 100,000 kilowatts thermoelectric ratio does not meet the national standard or alternative heat source thermal units. Optimal operation mode cogeneration units, strictly implement the "hot set electricity."
Pressure test must be carried out before the oil and gas boiler operation: either steam boiler or hot water boiler fuel oil fire tube in the boiler installation must be pressure test (ie, play water pressure). Because after long-distance transport, handling, installation, it is inevitable collisions and injuries through the boiler pressure test to discover defects promptly take appropriate measures in order to ensure the safe operation of the boiler. The following fuel gas-fired boiler to pressure test as an example:
