Hot selling gas hot water boiler for greenhouse
Use hot selling hot water boiler for greenhouse and hot water boiler structural principle profiles include hot water boiler electric water boilers, hot water boiler fuel, gas hot water boilers and coal-fired hot water boilers, hot water boilers that produce hot water boilers, it refers to the use of fuel the heat released by combustion or other thermal energy (e.g., electrical energy, solar energy, etc.) the water was heated to a nominal temperature of a thermal device. Use hot water boiler and hot water boiler heating bath mainly two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Principle structure of the natural circulation of the hot water boiler hot water boiler, inlet and outlet are taken over from the top of the drum, the water from the water distribution pipe guide and drop into the front side lower header pipe, through the waterwall tubes heating rise. The front drum, rear end plate is provided with impermeable boundary falling rising flow, only the lower half of the drum cross-impermeable partition plate. For the forced circulation, the water access to the front end of the lower header, the front drum increases to upper waterwall tubes (waterwall downcomer Cancellation time), and then transferred to the waterwall tubes downcomer side to side lower header, then into the side of the cloth water wall tube rose to the drum, and from the front row convection bank down to the next drum, and finally between the upper and lower drum and several circuitous flow of water from the rear end of the drum. No circulation boiler with economizer.
Energy-saving measures and methods of industrial boilers which industrial boiler energy-saving measures and methods which 1, to increase the capacity and improve the thermal efficiency of boilers and inefficient small compared to the large-capacity high-efficiency industrial boilers, can greatly improve the utilization of energy rate, so as to obtain greater economic benefits. Meanwhile, the cogeneration project enables conversion of exhaust or extraction steam turbine for heating, not only can reduce the loss of turbine exhaust steam, but also help to save coal resources. Industrial boiler thermal efficiency of China's low is a fact that can not be ignored, usually operating efficiency even lower. Therefore, improving the efficiency of industrial furnace hot pot, is crucial for energy savings. In one aspect, by improving the quality of the insulating material, thicker insulation, heat loss can be reduced. On the other hand, the use of secondary air system, can facilitate a more complete combustion of fuel, the effect is very significant. 2, the heating surface to reduce coking and fouling of industrial boiler during running, prone to coking, fouling phenomenon, resulting in increased and then decreased local resistance to the flow cross section. Not only conducive to smoke, but also so that heat transfer is reduced, further increasing the temperature of the flue gas. Industrial boilers and cleaning agent has a good cleaning effect, can be put in the appropriate amount sublimation decompose at high temperatures, with the heating surface of the coke, slag and contacts a chemical reaction can be automatically off after decomposition. Meanwhile, a method of periodically purging is also more effective in the early formation of fouling was loose state can be cleared periodically sootblowing. If the attachment is too long time, will translate into close like fouling, thus increasing the difficulty of cleaning up. 3, to ensure the quality of coal and industrial coal-fired boilers with coal is crucial, its moisture, volatile content factor for the speed of fire, as well as affecting the combustion temperature is extremely obvious. Maintain proper moisture content can be reduced with reduced leakage occurrence of coal and fly ash, coal seam and helps enhance the evacuation ventilation. If the moisture content is too high, will affect the speed and the temperature in the furnace, heat loss will be increased exhaust smoke. Industrial water boiler heating surface for scaling impact of large scale for each additional 1mm, the overall thermal efficiency of the boiler will be reduced by 3%. 4, many factors affect the lower exhaust gas temperature industrial boiler flue gas temperature, within the course of the economizer scale, cleaning up soot neglect of smoke in the furnace wall channeling smoke, poor treatment effect, can cause elevated exhaust temperature. On the one hand, to deal with the heating surface appears slagging, fouling and scale phenomena take timely measures to eliminate, minimize or avoid their presence. On the other hand, on the rear of the boiler heating surface is improved or increased. Industrial boiler flue gas temperature, objectively reflects the utilization of exhaust heat. But not as low as possible, the exhaust gas temperature is too low but not conducive to the normal operation of the boiler.
Furnace pulverized coal fired boiler is smaller than you: Today saw a piece of content, said: with the same capacity, oil-fired boiler furnace is smaller than pulverized coal. why? The following reasons: the size of the furnace volume, in the boiler capacity is determined, depending on the size of the volume of heat load. Volumetric heat load size is mainly determined by the type of fuel. After the fuel into the furnace, it will take some time to burn. Typically all the required fuel burn before leaving the furnace, the pulverized coal burnout is obviously longer than oil, i.e. coal flame longer than oil. To ensure long-term safe operation of the boiler, not only to prevent the boiler slag, and flue gas at the furnace exit is low to make the temperature at the start of the deformation ratio of ash flue gas temperature 50 ~ 100 ℃, at the outlet of the furnace and to prevent subsequent convection slagging heating surface. In many coal ash content, coal-fired furnace to control the furnace exit gas temperature typically of 1050 ~ 1100 ℃. The fuel oil furnace because very little ash, furnace slag is not dangerous, do not consider the problem of slagging furnace slag discharge outlet pipe, so the furnace exit gas temperature can be higher. For the above two reasons, the volume of the thermal load is higher than Pulverized fuel boiler. Pulverized volumetric heat load is about 145 ~ 185kw / m3, and the volumetric fuel burner heat load of up to 255 ~ 350kw / m3, so the same volume of the furnace fuel burner furnace capacity is relatively small pulverized coal fired.

In October 2016, my company and the China Dunhuang International Hotel signed a ZWNSL2.1-1.0 / W-Y.Q vacuum condensing gas hot selling hot water boiler for greenhouse to provide heating and hot water for the hotel. The boiler implementing the response to the national policy of environmental protection requirements and local environmental protection departments on a series of low nitrogen emission standard boiler requirements, in terms of design, manufacture, installation and other sectors have strict checks to ensure that the boiler safe and stable operation.
