gas fired industrial 4 ton steam boiler
Winter heating season is approaching, Jinan City, Shandong Province in response to the country clean, low-emission environmental requirements, increase efforts to support the promotion of winter heating clean, clean heating to further enhance the city level, issued on the issue clean winter heating engineering and operational capital subsidy Notice.
Second, the use of centralized gas boiler user, uniform implementation of preferential gas prices 1.71 yuan / cubic meter, the heating period and after the end of the third-party audit of gas consumption, gas will be the final settlement price (not exceeding Municipality department approved between the reference price) and 1.71 yuan / cubic meter price difference subsidy to the gas company, to purchase heating companies use non-city franchise gas pipeline business gas heating can be direct subsidies to heating companies.
Third, the use of electricity users centralized heating, heating period and by the end of the third-party audit by the electricity, the power company will operate the unit with the settlement price and preferential rates (level of 0.5 yuan / kwh, Valley Electric 0.25 yuan / kilowatt the difference between the time) subsidy to operate the unit.
Fourth, the use of formula household heating boiler user, purchase subsidy subsidy to the user equipment or units in accordance with Standard 2000 underwritten yuan / household. Temporarily performed using the sub-family user heating boiler gas prices during the step, performed in accordance with a first gear price urban gas prices; after the heating period, gas operation subsidies subsidies to users according to standard 1200 / household .
Fifth, the use of household electric heating type user, can also get subsidies. Subsidy ranges: The air source heat pumps, domestic electric boilers, heating cables, heating the carbon crystal plate user. According to the notification, the device according to the purchase subsidy subsidized purchase truly carbon crystal plate does not exceed 2,000 yuan / household air-source heat pump, domestic electric boilers, heating cables subsidy standard is 2000 Yuan / or household user to Advancer units. After the heating period, power to the user according to operating subsidies subsidies 1200 / standard household.
More details gas boilers should be promptly after use as a fired industrial 4 ton steam boiler plant drainage, heating, bath with gas boiler is a kind of fuel for the gas equipment (fuel gas-fired boilers), because it is compared with oil-fired boiler, electric boiler up more economical, which is widely used. After carrying out the gas boiler must turn on the water to be disabled. Why is that? We will come and detailed discussion about this issue today. To turn on the water when the gas boiler is disabled: gas boiler in the boiler water if the winter will put the cracking, there will be odor and summer long embroidered, so that the life of the boiler will be reduced. At the bottom of the boiler there is a turn on the water with the section of the door, then opened, gas boiler pipes in the water will flow back to the boiler, the boiler is done and the water on it. Water level controller SZB-IV (electrode type water level alarm) 1. When the normal level of + 30mm, pump control switch contacts are open, the pump stops working. 2. When the normal water level -30mm, pump control switch contacts in contact, the pump starts to work. 3. When the normal water level of + 50mm, a first group of electromagnets high gas boiler water level contacts the combined output high level alarm signal. 4. When the normal water level of the gas boiler -50mm, a second group of electromagnets in conjunction with the low water contact output low water level alarm signal.
New coal fire late, often appear off the fire bed fire, fire away from coal gate about 0.6 ~ 1.Om, burning furnace is not strong, high ash carbon content. For existing furnace arch structural problems, from improving fuel fire conditions, improve furnace temperature begin to transform the boiler. After the furnace arch after the transformation, the people stove fuel from coal gate 0 · 3mRP fire, the fire bed combustion intense flame full of good, strong rotation. Since lowering the front arch, the arch extended, reduced to about 1 2 throat formed between the arch of the original pitch. Where the enhanced mixing flow disturbances, reorganized stream, enhanced combustion furnace, to effectively improve the temperature of the entire front region and the arch of the furnace, to reach 1400 degrees, the condition of the fuel to improve ignition. 2. The ignition point of coal in advance, the temperature of the furnace to improve the ash carbon content decreased. Smoke swirling mix and strengthen the separation of coke particles in the flue gas, so that it falls on the fire bed and the new layer further fuel burn. Flue gas also strong swirl in the flue gas CO, H2, CH4 and other combustible combustion gases, thereby improving the thermal efficiency of the boiler is more than 4%. But also improve the boiler output to meet the needs of the production of steam, reducing environmental pollution, expanding the scope to adapt varieties of coal.
The preparation you need to do before the boiler is installed
The boiler is a device that supplies steam and hot water for industrial production or daily life. After the company purchases the boiler model, it needs to consider the installation problem. The installation of the boiler is directly related to the important steps of the smooth operation of the boiler, except for the installation of the auxiliary machine. Also need to pay attention to the preparation before installation.
1. Handling the registration of natural gas boiler installation: According to the “Safety Supervision Regulations for Steam Boilers”, the units that use the boilers should go through the registration procedures one by one. The boiler use unit shall have a person responsible for the boiler installation work, responsible for contacting the local boiler supervision agency and filling out the installation notice. When the boiler is installed, it must be attended by a furnace, and it is equipped with a pipeman, a fitter, a hoist, a cold workman, an electric welder and an auxiliary worker.
2. Determine the installation location and qualification of the boiler to determine the installation location. The boiler installation unit must have a boiler installation qualification certificate issued by the superior authority in accordance with the installation scope.
3. Inspection of boilers and accessories: Before the installation of natural gas boilers, the boiler body, combustion equipment, components, natural gas boiler auxiliary machines and accessories shall be inspected and accepted according to the drawings, and records shall be made. If it is found that the relevant standards are not met, it shall be promptly submitted to the factory. .
