The fuel regulation subsystem of 150l thermostat hot water boiler supplier adopts a feed-forward-feedback cascade control system similar to the steam turbine power-frequency electro-hydraulic control system. The main regulator adopts the proportional regulator, which corresponds to the frequency difference amplifier in the steam turbine power-frequency electro-hydraulic regulating system. The proportional band is equivalent to the unequal rate of the steam turbine. The size of the proportional band represents the capacity of the hot water boiler with load, and the larger the proportional band, the greater the load capacity of the hot water boiler. The capacity of hot water boiler with load is stronger; The auxiliary regulator adopts the proportional integral regulator, which corresponds to the power regulator in the power-frequency electro-hydraulic regulation system of steam turbine, and introduces the feedback signal of fuel quantity to the power-frequency electro-hydraulic regulation system of steam turbine. The effect of the first stage pressure signal of steam turbine is to eliminate the spontaneous disturbance of the fuel quantity of hot water boiler quickly. Hot water boilers are mainly used for heating and bathing. The hot water boiler circulates the hot water of the heat preservation tank through the hot water circulation pump and heats the hot water of the water tank again and again so as to achieve the purpose of bathing. The hot water boiler circulates the hot water of the heating pipe through the hot water circulation pump, and meets the requirement of people's heating through the radiator (radiator), and the hot water boiler and the hot water circulation pump cooperate with the heat exchanger can realize the double function of bathing and heating. The inlet speed of hot water boiler before start-up should not be too fast, usually no less than 4 in winter H, 2 to 3 hours in other seasons, especially at the beginning of the inflow. The inlet water temperature of a hot water boiler is generally at 50 ℃ 90 ℃, so that the difference between the feed water temperature entering the drum and the wall temperature of the drum is less than 40 ℃. The inlet water temperature of the gas-fired hot water boiler without complete cooling can be compared with the drum wall temperature, otherwise, the inlet water speed should be slowed down. When the feed water enters the drum, it always contacts the lower half wall of the drum first. If the difference between the feed water temperature and the drum wall temperature is too large, the speed of entering the water is fast, the upper and lower walls of the drum, the inner and outer walls will produce a larger expansion difference, resulting in a greater additional stress to the drum. Causes the steam drum to deform, produces the crack when serious. Because the wall of the drum Thick, slow expansion, and connected to the drum wall thin wall, expansion faster. If the inlet temperature of gas-fired hot water boiler is too high or the inlet speed is too fast, it will cause uneven expansion, crack of welding joint and damage of gas-fired hot water boiler.

Regular inspection:

Just like people need to receive health examination in case of health problems, the boiler products also should process regular inspection, especially when the heating season is over. Professional inspectors inspect the boiler body and its every spare parts, so that they can find out which part should be repaired or replaced.

Accelerate the implementation of the relevant arrangements for the deployment of national, provincial and develop natural gas and other clean energy. According to Yi gas of the gas, the electric power should be the principle, and actively guide enterprises to implement energy clean energy alternative, 2020, the basic completion of provincial trunk pipeline construction, the basic realization of natural gas every county, to further improve the urban and rural distribution pipe network construction , the city's natural gas consumption reached 570 million cubic meters, the proportion of non-fossil fuels in total energy consumption to reach the provincial requirements. Orderly development of hydropower, nuclear power is safe and effective, optimized wind energy, solar energy development layout, local conditions to develop biomass energy, geothermal energy and so on. Where the conditions of availability of resources, to encourage the development of county biomass cogeneration, biomass briquette boilers and biogas. Orderly development of natural gas peaking power plants and other interruptible user, in principle, to new natural gas cogeneration and gas chemical projects. Continue to implement the priority generation and purchase of electricity system to ensure the city's renewable energy generation full protection of the acquisition.

Strict new coal project access, the implementation of the reduction of coal instead. According to Blue Sky to win the Battle of three-year action plan calls for no new 35 steam tons / hour high-polluting fuel boilers. By 2020, the city's coal accounts for the proportion of total energy consumption fell to 42.8% or less, the city's total coal consumption decreased by 5% compared with 2015. According to focus on the use of coal and clean use of principles, focusing on reduction of non-coal for electricity, increase the proportion of electricity from coal in 2020, the city's electricity and central heating coal proportion of total coal consumption reached provincial requirements. Continue to promote alternative energy coal and oil, replace reached the provincial requirements.

Vigorously for shutting down environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance, according to plans to phase out other coal-fired thermal power generating units. For shutting down the unit's capacity, coal consumption and emissions targets, allowed to trade or replacement, can co-ordinate arrangements for building the capacity of ultra-low emission coal-fired units. Strict control of new coal-fired units installed capacity in the region rely on new clean energy generation and transmission to meet outside the main electricity consumption.

Consolidate construction achievements combustion zone ban, increase efforts to eliminate small coal-fired boilers. According to Blue Sky to win the Battle of three-year action plan calls for phasing out the 10 steam tons / hour and coal-fired boilers, the county level and above urban area basically eliminated tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities ; 10 basically eliminated city steam tons / hr steam 35 tons / hour of coal-fired boilers; 35 t steam / hour and more polluting fuels and ultra-low emissions boilers complete energy transformation; low-nitrogen gas boiler is substantially complete transformation; urban built District ultra-low emission biomass boilers implement reform.
