Pressure steam boiler shutdown fire you do not know the techniques and precautions steam boiler refers to water heated to a certain temperature parameters and the production of industrial steam boiler, the water in the steam drum is heated to become vapor, fire emits heat in the furnace, It is the principle of the steam boiler. Steam boiler belongs to special equipment, design, processing, manufacturing, installation and use of the boiler must be supervised by technical supervision departments, users only get to use the boiler permits to use steam boilers. Fire pressure steam boiler shutdown is interrupted by slowly burning until the load drops to zero until a planned shutdown. Specific steps are as follows: 1, to reduce boiler load, according to the length of time of shutdown, the seam thicker, the thickness is generally not more than 200 mm, suitable to accelerate the speed of the grate. 2, the distance to the thick seam slag is about 1 mm grate stop rotation of the drum is stopped, the operation of the induced draft fan, blowing off a small segment of the regulating plate stopper and dampers qs, relying on natural ventilation to maintain coal lean-burn, the sewage, boiler water level will rise to the maximum allowable level. If the fire burn coal gate, grate can be switched on again, the gas will move back some distance. 3, the recovery boiler needs to run, as long as the opening lead, a blower, to adjust the smoke, and the wind baffle plenum segment adjusting the opening degree of the shutter, the adjustment of combustion steam boiler seam thickness to be normal, start grate, to resume operation .
Use hot community water boiler dealer 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.
Daily maintenance of gas-fired boilerDuring operation, the gas-fired boiler should pay attention to the following points: (1) the gas-fired boiler does not allow positive pressure combustion or smoke injection in the furnace because it is easy to burn out the coal hole cover. (2) the bottom floor plane of the gas-fired boiler shall not be watered up in order to prevent damp corrosion. The gas-fired boiler shall be inspected every 2 weeks and every 3 months after the operation of the gas-fired boiler. (1) the gas-fired boiler shall be inspected and repaired in an all-round way after the operation of the gas-fired boiler every 3 months. (1) the gas-fired boiler shall be inspected inside and outside the boiler. If the pressed part of the weld, steel plate inside and outside corrosion phenomenon, if found in serious defects should be repaired in time, if the defects are not serious, the next time the furnace shut down repair, if found When suspicious, but does not affect the safety of production, records shall be made for future reference. (2) after inspection, boiler primer may be applied on the surface to prevent corrosion. 4. Gas-fired boilers and boiler base shall be painted at least once a year. 5, There are dry and wet methods for the maintenance of gas-fired boilers: dry method and wet method. Dry maintenance method should be adopted when the boiler is shut down for more than one month. (1) dry maintenance method: after boiler shut-down, the boiler can remove the water from the furnace, and the method of dry maintenance shall be adopted under one month. (1) dry maintenance method: after the boiler has shut down the furnace, Thoroughly remove the internal dirt, rinse clean, dry the furnace with a slight fire (be careful not to fire), and then apply a 10-30 mm diameter lump of quicklime. The plates are arranged and placed in the pan, without contact with the metal. The weight of quicklime is calculated at the volume of 8 kilograms per cubic metre of the drum, and then all manholes, hand-holes, pipe valves are closed and checked every three months. If the quicklime is broken, it needs to be replaced immediately. When the boiler is re-running, the quick lime and the tray shall be removed. (2) Wet maintenance method: after the boiler has stopped the furnace, the boiler shall discharge the furnace water, thoroughly remove the internal dirt, rinse it clean, and reinject the treated water until it is fully filled. Heat the furnace water to 100 ℃, let the gas from the water out of the furnace, and then close all the valves, where the climate is cold, do not adopt moisturizing method, so as to avoid the furnace water Icing damaged the boiler.
The use of central heating hot community water boiler dealer is the best choice for winter heating in northern China. Shanxi Province is located in Chang Darrow Heating Co., Ltd. mainly provides heating and post-service maintenance of heating equipment, heating clients involved in enterprises and institutions, office buildings, residential housing and a variety of commercial and other entertainment venues. With the wide blue sky covered Battle of the project, China's gradual increase in the proportion of heating for cleaning, heating, Ltd. Dalong Chang respond positively to the call of national policy, high pollution intensity wishing previously used, low thermal efficiency of coal-fired boiler to replace the traditional use hot water boiler clean fuel. After comparing many boiler manufacturers, choosing the optimal selection, determined and professional cooperation parties do fast boiler fuel boiler cleaning equipment. Providing a fast side 35 MW gas tube hot water boiler (SZS35-1.6-Y.Q) according to their actual needs.Free Chat
