how to calculate boiler price zbg boiler

Boilers are our life's products, and gas-fired how to calculate boiler price zbg boilers are energy-saving and emission-reducing products, which are loved by very customers, but in the use of gas-fired boilers, due to the problem of water quality, the boiler will be covered with scale. What is the effect of the scale on the boiler? The formation of boiler scale after a long period of operation, the inevitable occurrence of scale, corrosion problem, the main reason for boiler scale formation is that the water has a hardness component, after the high temperature, high pressure evaporation concentration, the main reason for the boiler scale formation is that the water has a hardness component, after the high temperature, high pressure evaporation concentration, A series of physical and chemical reactions take place in the furnace, eventually forming a hard, dense scale on the heated surface. Harm to gas-fired boiler 1 The heat transfer effect is reduced and the corrosion factor under the scale is 2, which results in the decrease of boiler water wall furnace heat absorption, the increase of boiler outlet temperature, the increase of boiler loss 3, and the reduction of heat transfer effect after scaling in the water wall. It may lead to the increase of the wall temperature of the water wall and the explosion of the tube wall of the water wall, which will affect the safe operation of the boiler. Scale is the first harmful factor of boiler, and the main cause of boiler accident. Its harmfulness is mainly manifested in the waste of a large amount of fuel: because the thermal conductivity of scale is only a fraction of that of steel, the heat transfer will be blocked after scaling on the heated surface. In order to maintain a certain output of the boiler, it is necessary to raise the temperature on the side of the fire, thus Causes external radiation and exhaust smoke to cause heat loss. Boiler cleaning gas-fired boiler can use high-efficiency environmentally friendly non-corrosive cleaning agent to clean gas-fired boiler, cleaning agent to clean the scale completely dissolved, so that the equipment tube exposed metal primary color, reduce the effect of scaling and biological algae sludge. At the same time, it can peel off iron oxide and ferrous oxide, prolong the service life of gas-fired boiler and reduce energy consumption.

Electric heating water how to calculate boiler price zbg boiler works belonging horizontal electric heating hot water boiler power steam boiler furnace using the electrical control cabinet separated manner to avoid thermal aging of the electrical components affect the service life. Electric tube using domestic and international high-quality products. Normal service life of 20,000 hours, and nearly 99% thermal efficiency, quiet, clean, environmentally friendly, without emission of nitrogen oxides (nitrogen oxides) into the atmosphere. PLC control system operation, no buttons, no pointer, touch screen, Chinese and English display, man-machine dialogue, authorization to operate, real-time information, auto-flip. All electrical components are CE and CCC certification mark to ensure product safety and service life. Centralized heating elements each beam flange connection, has a simple structure, high mechanical strength, safe, reliable, easy to replace, and long service life. Having a simple structure, high mechanical strength, easy to replace, and long life. Vapor space, good steam quality, electromechanical components separately installed, the electronic control elements away from heat, allows for heat dissipation. It can be used in parallel with one or more units. PLC programmable control and display computer, automatic control of temperature through the man-machine interface. The display shows the operating parameters and equipment failure alarms. Electric heating boiler is relatively simple structure. Connected triangulation electric heating tube, the three heating pipe connected to a set of external cover connected to an external electrical device on the flange, electrically heated screen disposed in the heating process externally medium heating tube group is completed in the cylinder. No need to lay pipes. It is provided with water inlet, hot water outlet (or steam), safety valves, pressure gauge, and a drain valve on the wiring board main body simplified. Works electric heating boiler feed water metal pipe heated by electric heater, electrical energy directly into heat (hot water or steam generation). It does not require burning by the chemical energy into thermal energy, and therefore no need to provide the air required for combustion of fuel, does not require emission of harmful gases and ash in full compliance with environmental requirements. Electric boiler electric heating element wide range, depending on the form of heating elements, generally divided into resistive, and thin film electrodes. Resistance to a high impedance resistor type tubular heating elements. After power on, tubular heating elements generate heat, hot water or steam into the water. Tubular heating element from the metal shell, and an oxide conductor layer. The advantage of this element is not charged, the use of safe, does not pollute the water quality. The problem is to increase the capacity of the boiler is dependent on the number of tubular heating element and the boiler load is adjusted according to the number in operation. Thus, the electrical heating element arrangement limits the capacity of the boiler. Works electrode element electrode is the electrode into the water, using the water resistance of the high energy directly into electrical energy. In this conversion process is almost no energy loss. A common electrode is divided into electrode type element and a high pressure type electrode type. Electrode very safe operation of the boiler, the boiler will not dry burning phenomenon. Once the furnace because the water is cut off, the channel between the electrodes is cut off, the current is zero, the boiler is automatically stopped. Electric film Electric film heating technology is a new technology developed in recent years. It has a higher specific resistance wire heating electric conversion efficiency. The principle is sprayed on the surface of the semiconductor thin film enamelled steel (metal oxide), i.e., microspheres electric material, to achieve high-power electric conversion. It has a wide range of applications, long life, high current impact resistance capability, substrate adhesion, cold resistance, high thermal shock damage resistance for a variety of base materials, simple equipment, less investment, low requirements for the process operating environment features.

It consumes the most is the use of fuel in the how to calculate boiler price zbg boiler, to make energy-saving measures must first start from the choice of fuel. In the current economic conditions, there are three main boiler fuel, namely the solid fuel, liquid fuel and gaseous fuel, three different heat generated by the fuel which is not the same, the degree of harm to the environment is not the same.
