food natural gas steam water boiler for sale

Gas boiler which has few parts of the main gas boiler: the enclosed pipe chimney pipe tube sheet base gas outlet steam dryer Confining the majority of the peripheral tubes to form a complete gas boiler. The main effect of gas boiler: the combustion of the fuel is heated by the feedwater temperature and the exothermic heat of the flue gas with a heated surface, so that a final water into superheated steam having a quality of qualified certain parameters. The water in the boiler to go through preheating, evaporation, overheating in three stages in order to become superheated steam. In fact, in order to improve the efficiency of the steam power cycle, there is a fourth stage, i.e. re-superheating stage, soon after the high pressure turbine expansion work to reduce the pressure and temperature of the steam back to the boiler is heated and then sent to the low pressure turbine cylinder continues to work. In order to meet these four phases change, the boiler must be arranged in the respective heating surface, i.e. the economizer, water wall, superheater and reheater. Superheater and reheater disposed in an upper horizontal flue backpass and functions of the fuel system is to ensure the desired fuel burner. The fuel oil burner system are: tubing and fittings, pumps, solenoid valves, nozzles, heavy oil preheater. The gas burner mainly a filter, pressure regulator, solenoid valve, and then firing solenoid valve, the fuel valve. Economizer disposed in the lower back pass. In order to utilize flue gas heat of heated air required for combustion, usually air preheater arranged after the economizer. Some additional preheating large boiler superheater heating surface or in the furnace, and then heat-receiving surface.

Thirteen Five release plan indicates that China's move towards green development pace firmer, Beijing SASAC Building Materials Service Center from its start, the use of green boiler heating for low nitrogen as the primary task before the onset of winter. SAC Building Materials authorities after preliminary investigation and after the screening, the other fast boiler R & D experience in the field of boiler cleaning two decades expressed appreciation can, in August 2017 signed a five Thalia T6 series one boiler and two vacuum with fast Boiler condensing gas boiler products contract.

Strict accordance with the operation of the gas steam boiler feed water softening process is provided gas steam boiler fouling not only reduces the thermal efficiency of the boiler, but also increases the temperature of the boiler heating surface, damage to the heating surface, even causing the boiler explosion. Thus, soft water treatment equipment, strict accordance with the operation of the boiler feed water softening processing apparatus, the control of boiler feed water quality, delay the formation of scale. At the same time, real-time control the size of the boiler, boiler scale control, cleaning the scale, if necessary, it is very important. Since the gas steam boiler and vapor - water heat temperature is higher than the temperature of the air system of the boiler room, part of heat to the surrounding air by radiation and convection, which became the heat loss. boiler. Accordingly, when the insulating layer and the heat pipe of the boiler system damage or leak is detected, it should be repaired, to reduce heat losses. Steam boiler burner gas noise increases, mainly because of lack of or close the valve in the oil passage into the oil, oil filter plugging; or into the oil due to the low temperature viscosity is too high or oil pump. Temperature is too high; oil pump failure; fan motor bearing damage; dirty because the turbine wheel, the device too loud. When said failure when using gas boiler, and since the viscosity of the oil is too high, atomization is not easy (heavy oil); and because the distance between the nozzle and the cyclone unsuitable; In addition, since the burner worn or dirty; also because reserve tank temperature is too high, leading to the oil pump steam; oil boiler or because the oil is hydrated. Gas steam boiler feed water containing various impurities and calcium and magnesium scale substances, boilers inevitably expanded. Very low thermal conductivity of the scale, once contaminated surface is the surface heat, the exhaust gas temperature of the boiler will increase, and due to the increase in thermal resistance, heat loss of the exhaust gas will increase. Experimental data show, 1mm scale formation in boiler heating surface, the heat loss of the exhaust gas will increase from about 2-4%. Scale thicker boiler heating surface, the greater the resistance, the lower the thermal efficiency of the boiler.

Fangkuai boilers take you to know that horizontal steam boilers are usually used in a very large number of models, depending on the fuel, the working principle, and the different structures of the boiler itself, which are divided into many different types of boilers, and they are divided into many different types, depending on the fuel, the working principle, and the different structure of the boiler itself. In the case of steam boilers, there are also ordinary boilers and steam boilers, for this horizontal steam boiler, its characteristics are not the same. The boiler arch is made of refractory concrete. The rear arch is low and long, so it burns well. The two-wing flue and side wall brick are made of refractory brick. Boiler front wall, rear wall using universal refractory brick. The air distribution of the grate is reasonable, and the combustion chamber is larger. The applicability of coal is strong. Suitable for all kinds of bituminous coal or anthracite, mixed coal. It burns well. Because the high temperature flue gas first enters the settling chamber and then into the two-wing flue from both sides, and the front smoke box, so the smoke elimination and dust removal effect is good. The water circulation is simple, the compressed parts have reasonable structure and can run safely under the condition of ensuring water quality. The burning equipment is a fast-loading grate. The burning equipment is manufactured and installed in the factory and installed directly on the ground after transportation to the site. It has the advantages of reasonable structure, compact structure and low steel consumption, which makes the boiler's performance, weight and structure size obviously advanced compared with the domestic products with the same capacity. The boiler type is horizontal fast loading water Fire tube boiler, working fluid natural circulation. The boiler heat transfer system consists of a boiler drum, a left and right header, and a water wall. The heating surface is mainly composed of a furnace water wall, a part of the boiler drum and a convection tube bundle in the boiler tube.
