china biomass fired steam generator prices
Throat automatic electric supply system of the china fired steam generator prices, steam drying steady flow supplied to the user. When the water into the tank, the power switch, controlled by the drive signal, high temperature solenoid valve is opened, the pump work, is injected through the check valve furnace. When the solenoid valve, the check valve is clogged or damaged, the water pressure reaches a certain overpressure valve through overflow back into the tank, to protect the pump. When the tank without water or residual air in the pump piping, air not only into the water, as long as the rapid exhaust through the exhaust valve until the discharge water, close the exhaust valve, the pump will function. The main water supply system component is the pump, they use a multi-stage vortex pump of higher pressure and a larger flow rate, using a small part of the diaphragm pump or a vane pump. Stainless steel mechanical float level controller for generator furnace large volume, the working pressure is not stable, but easy to washable, maintenance and repair. Furnace boiler body generally use special seamless steel pipe, elongated upright. Most electric heating system or a heating tube used in a root canal curvature combination of stainless steel heating, while the surface load is generally about 20 W / cm. Due to the higher pressure and temperature when the generator is working properly, the safety protection system in the long run can make it safe, reliable and efficient. It is generally produced using high strength copper alloy valve, check valve, an exhaust valve, implement three protection. Some products also increased the water level in the glass tube protection device, increasing the user's sense of security. Product choice points: Electric steam boiler main control parameter is selected nominal evaporation, thermal efficiency of the boiler design, the rated steam pressure, the rated input electric power and the like. Use of electric steam boilers should meet the requirements of national and local restrictions related standards, norms. Using the selection of appropriate thermal storage electric boiler system, i.e., when the low electric power, the heat stored in the heat storage medium; at peak power stage, the heat stored in the heat storage medium released for users. It features electric boiler thermal storage system is different for peak electricity prices, operating cost savings for the user, and by peak load shifting power grid, good for grid security, economic operation. Electric steam boiler with the steam accumulator reservoir may be higher, the higher the heat of the argument, but the high electric steam boiler plus steam accumulator system cost, operation and management require a higher level, and therefore, do not ask for the heating parameters heating, living, air conditioning system, electric steam boiler plus steam accumulator system is rarely used. Electric power distribution chamber should be supplied directly to the boiler, the discharge conveyor can be used, or a metal cable. Determining the load and the number of electric boiler, boiler room should be combined transformer capacity equipped with comprehensive consideration. Many boilers can share a transformer, but not multiple transformers to supply a common boiler. Taipower power single steam boiler should not be greater than 2.4MW. Steam boiler feed water pot outside the general chemical water treatment, water quality should be specified. Installation and construction, installation points, boilers and auxiliary equipment, water treatment equipment should meet the technical requirements of the device manufacturer. Equipment foundation must be the arrival of equipment and after verification and design drawings before construction. The highest point of the pipeline deflation, the lowest point turn on the water. Acceptance pressure test after the pipe installation. Electric boiler room should all be grounded electrical equipment and heat storing devices. Precautions: power supply voltage can not exceed ± 5% of the rated voltage. Choice of fuel kerosene, diesel oil, do not use gasoline and heavy oil; when winter temperatures below 0 degrees, 0 # diesel oil are often solidification phenomena, not to use, it is best to use -10 # diesel or kerosene. You must be ground wire construction requirements:! Strength of electrical wiring must be separated, such as walking level sensors, pressure sensors and other electrical control of strong and weak lines output lines of the controller separately. When the installation site, should not wear in the same PVC pipe as arranged in parallel should be held at least 200mm intervals. Ban placed around the boiler gasoline, bananas, water and other inflammable and explosive materials. When using a gas boiler-room electronic leak detection alarm device should be installed to prevent accidents.
Eliminating the problem of pressure test: GB150-1998 "Steel Pressure Vessel" Article 3.9 states: "to not make container pressure testing in accordance with the provisions of 3.8, the design unit should put forward measures to ensure the safe operation of the vessel, and note on drawings Ming "There are many standard deviations the user's understanding of this provision, is summarized in the need to clarify the following two questions: First, under what circumstances can relieve stress test? Second, the measures may be required after relieve the pressure test? When the catalytic cracking unit with a regenerator and a large reactor and the heat insulating layer can not withstand those based hydraulic test: in fact, only relieve pressure test performed Spot welding large pressure vessels for pressure testing the impossible, such as water by weight of the pressure vessel and the like. In other words, the reason why the pressure test exemption, because they do not have the container or a pressure test, or simply not pressure tested. In short, rather than eliminating means you can not do not do it, it is not without basis as a general pressure test in the factory production of pressure vessels. It should be noted that the pressure here means a pressure test test.
Rated evaporation gas steam boiler rated evaporation to choose the size of the boiler steam boiler is a proper noun, which is the power of steam boilers. Calculated: (ton unit) the general power china fired steam generator pricess are rated by evaporation. Rated evaporation is a boiler to heat water per hour becomes steam production. This is the main argument when we need to consider the selection of steam boilers. How to choose the right Rated evaporation it? Generally, we first calculate the own use of steam per hour required, if the hotel laundry room and hospital disinfection equipment, you can see through the steam parameters parameters to calculate laundry facilities needed for every hour; if it is the plant process steam then it can be calculated per hour of steam required by the process. After calculating their required amount of steam we can choose the boiler, and generally we need to select the rated evaporation than we calculate the steam boiler with 20% of the amount. Because there may be some cases in the actual use of the process to increase the amount of steam, or steam boiler does not reach its ideal operating conditions. Here should be noted that, in accordance with our steam boilers are marked on the boiler rated pressure to calculate the rated evaporation, and some foreign steam boiler is zero pressure steam production to the subject. Such as poly rated pressure force is 1.0Mpa steam boiler, the steam temperature is 184 deg.] C to produce, while the zero pressure steam production refers to the production of steam output of 100 deg.] C, to the middle of the big difference.
Our jewelry processing company in the automotive production, many processes require energy, to be honest we really a headache on the choice of the boiler, thanks met specializes in the research and production of fast square boiler boiler!
