14th szs gas hot water boiler in vietnam

Technical characteristics: the overall cost of natural gas boiler is half the coal-fired boilers, and operation costs are four times as coal, a ton of steam needs to burn about 80 cubic meters of natural gas, and coal-fired no more than 0.185 kg, the economic accounts will be considered . Select the gas boiler it under certain conditions choice of last resort. As well as on the performance of the gas is better than coal. In principle, they are heat transfer equipment, the difference is that on combustion, complex grate or coal, coal preparation, etc. as well as coal needs, while gas only burner that simple. Use of cleaning gas boiler: boiler after a long run, the inevitable emergence of scale, mainly due to the scale of the problem of corrosion, formation of boiler feed water with hardness components, through subsequent high temperature and pressure continuously concentrated by evaporation in a furnace a series of physical and chemical reactions that ultimately form a hard heating surface, a dense scale, resulting in reduced heat transfer and the effect of corrosion under the scale factors, will result in reduced boiler waterwall furnace heat absorption, furnace outlet temperature of the boiler is increased, so that increased boiler losses. After scaling while reducing the heat transfer within the water wall, water wall tube wall temperature may lead to increased water wall lead to burst pipes, affect the safe operation of the boiler. The first of scale is detrimental boiler, the boiler is the main cause of accidents, the danger main problems: wasting a lot of fuel: Because only one of very few steel thermal conductivity of scale, so when the heating surface fouling will heat blocked, in order to maintain a certain boiler output, it is necessary to increase the temperature of the side of the fire, so that the external radiation and flue gas heat loss. Now it can be used efficient and environmentally non-corrosive cleaning agent gas boiler cleaning, cleaning Fu World Tektronix cleaning agent scale was completely dissolved, the equipment expose the metal tube primary colors, because the reduction of algae and biological sludge fouling effect. At the same time stripping the role of iron oxide and iron oxide Asia, extended gas boiler service life, reduce energy consumption and improve productivity.

Small oil-fired boiler flameout protection device use: small oil-fired boiler furnace space Product Introduction small oil-fired boiler of large and adaptable load capacity. Rational design of steam separator apparatus built to meet user requirements need to use higher quality steam. Furnace open manhole, head holes, hand holes, to facilitate the internal furnace to clean up, make repairs, maintenance is very convenient. Boiler safety interlock with multi-level protection: protection pressure switch (higher than the set auto stop and pressure), the low water level protection (boiler water level is below the warning level in the body, and automatically cut off power alarm), the protection valve (boiler pressure exceeds the pressure of work, discouraged automatic blood pressure), ensure that the boiler in a variety of conditions foolproof, secure home. Mechatronics combined organic appearance, new sophisticated, compact, less space, easy to transport and install. Thermal insulation materials and the use of new high-quality white color plate package, lighter in weight, good insulation properties, beautiful, not rust. Use flameout protection device for small oil-fired boiler to prevent furnace explosion, the fuel (gas) boiler must be set flameout protection means functions combustion in the monitoring of the furnace (including an ignition when the ignition failure or combustion halfway off, typically 5 seconds the re-ignition, run 1 second, off into the oil (gas) solenoid valve, and turns on and audible alarm signal, when the blower continues to operate, the residual gas was purged of combustible furnace, after 20 to 30 seconds after purging, and various auxiliary blowers automatically cut off power, the boiler stop running.) by the flame monitoring and control device component. Role is to monitor the flame control device signals the presence of a flame or interrupted. The main use of the photomultiplier tube, a photovoltaic cell and photosensitive resistance, they have an infrared type or ultraviolet type, A photoelectric conversion element, the working principle of the light converted to the corresponding strength of the radiation intensity of current. And a linear output state, sometimes weak induction current, through amplification, in order to have an effect on the controller.

Gas-fired steam boiler FAQ boiler for your boiler sorted out 30 common problems and solutions, do not forget to share a small partner after learning finished oh. 6, the main factors which influence the rate of wear of? ① flue gas, the concentration of the surface shape of the particle size and hardness ② ③ material in the flue gas flow rate of the material is worn element, the direction of relative movement of material with the hardness of the wear element ④ greatest influence It is the speed of the airflow, proportional to the cube of wear and speed. 7, how to control the bed temperature between 850-950? ① ash does not melt at the temperature, thereby reducing the risk of slag settle ② The temperature nitrogen having a high desulfurization efficiency ③ combustion gases at this temperature ④ less of the gas at this temperature the coal is not an alkali metal sublimation can be reduced slagging of the heating surface. 8, why should the torch boiler? Soda boiler system equipment such as part of desuperheating water, startup bypass, superheater, reheater piping system, due to the structure, material, arrangement, etc. are not suitable for chemical cleaning, so newly installed inside the boiler required physically remove remaining debris before officially put into operation, it is produced using the steam oven of the present systems and devices torch soda process. 9, common maintenance method, which has several boiler (1) Wet protection: with ammonia, liquid ammonia method, a method to maintain water pressure, steam heating method, a method of alkali, trisodium phosphate, and a mixed solution of nitrite Protection Act;? (2) dry protection: drying method (with pressure drainage) and desiccant process. 10, what? (1) steam with water vapor causes of quality deterioration (steam pollution). Boiler feed water containing impurities. After heating into the boiler feedwater into steam, most of the impurities are also transferred to the boiler water, so many times the cycle, increasing the impurity concentration of boiler water. Boiler water containing a high concentration of impurities is carried with the steam is called saturated steam water vapor with a machine called water carried, the first reason is contaminated steam. (2) steam soluble salt. The boiler at a higher operating pressure steam dissolves some salts, referred to as selective carry steam soluble salt, which is the second reason steam contamination.
