Hot water boiler in the school dormitory and classroom building are generally used for central heating, drinking water and bathing water aspects of teachers and students and so on. Shanxi Linxian County high school is an important educational school personnel training for the community. 2017, the school responded positively to national coal to gas and other environmental policies, but also to provide students with a more favorable living and learning environment, the school decided to phase out conventional coal-fired boilers, clean and environmentally friendly replacement for the gas boiler. After getting to know and choose the boiler industry, major companies, determined cooperation with professional production of clean fuel boiler fast boiler-by-side to provide a fast 4.2MW integrated condensing gas hot water boiler circulation pump (WNS4.2-1.0 / 115 / 70-YQ).
For details about the hot water boiler circulation pump: the use of fuel combustion boiler is released to heat or other energy working medium is heated to a certain device parameters. A hot water boiler for heating the water so as to increase the temperature into the hot water boiler. Hot water boiler is important to the national economy heat supply equipment. Electrical, mechanical, metallurgical, chemical, textile, paper, food and other industries, as well as industrial and civil heating boiler needs to supply large amounts of heat. Saving effect of hot water boiler design structure: during use of the hot water boiler can be useful in the process of complete automation in the necessarily extent, so that the combustion will boiler water temperature and the fuel may be automatic control, energy saving can be reached then the purpose, in general, automatic hot water boilers commonly used in hotels and guesthouses, saving the cost of personnel to deal with. The primary hot water boiler is the choice of a full butt weld wet back structure, the disadvantages of such a structure after the device processing chamber smoke long time by high temperature flue gas erosion, must be easily damaged or the like on the extent to ensure that the boiler can always be kept safe and reliable operation Happening.
How to avoid steam boiler with a steam condenser water use and benefits of this kind of boiler steam boiler, for now, it is widely used, but a particular kind of boiler common and often used to, so the need for a comprehensive knowledge and understanding, so as to derive relevant expertise, and to increase their amount of knowledge, rather than wasted every opportunity to learn. 1. How to avoid steam boiler with a steam severe water? Steam boiler in the course, if you want to avoid this serious problem with water vapor, the following should do a good job in these areas, which is specifically as follows: 1 aspect: boiler feed water and steam boiler water quality and testing , must meet GB1576-2001 "industrial boiler water quality," the provisions of this standard in the requirements must be strictly enforced, can not be careless and lax. Welding the inner drum member boiler inspection, the drawings and installation meets the requirements, and the installation is in place, focusing check waterwall steam duct closing plate and the header inserted at the drum and the drum: Aspect 2 as appropriate, and whether there are good quality welding, welding defects if there is a problem. In addition, the welding between the sealing sheet tightly and also has good welding quality, soda or a mixture of steam enters the tube through an underwater orifice, thereby generating the above-described problem. Aspect 3: Check to see if the gap between the plates underwater seal tightly, and steam as well as inter-well plates and whether uniform and sealed drum connection. 2. Is gas steam boiler condenser plus without a difference? Gas-fired steam boiler plus without condenser, from a professional point of view, the gas steam boiler is a certain influence, and the condenser boiler plus you can bring some benefits, are as follows: 1 benefit: through the condenser heat fill the water tank, it can indirectly increase the temperature of the boiler water, boiler of the steam to shorten the time to reach in a short time using less natural gas can be an equal amount of steam. 2 benefits: lower exhaust gas temperature, improve the utilization of natural gas and the achievement of environmental protection. 3. Which valve steam boiler heating system will be used? Steam boiler heating system, the valve will be used, there is a main shut-off valve, drain valve, ball valve, safety valve four valves, wherein the ball valve is in the water gauge, a safety valve in the water supply system is of. A valve and drain valve that is rarely used, and are not common.
The boiler body is composed of a vertical upper and lower drum and a convection tube bundle, and a water-cooled wall tube is arranged in the combustion chamber, and a pot-and-gas device such as steam-water separation and continuous sewage discharge is arranged in the upper drum, and a regular sewage device is arranged in the lower drum, and the tail portion is arranged There is an economizer (air preheater), the furnace arch is made of refractory clay bricks, and the outside of the boiler main body is a three-dimensional shield shell. The szl series boiler is a coal-fired biomass water tube boiler.
