Zhejiang mainly caused by the steam pressure change and the change amount of fuel steam load. Its dynamic characteristics are as follows: 1, the vapor pressure of the fuel quantity variation characteristic disturbance: in the case of a constant steam load, the amount of fuel boiler startup recommendations banks engineerings step disturbance occurs, which is the object is not self-balance, having large hysteresis and inertia.

Recently, Shaanxi Province issued a notice "issued four Battle 2019 program of work". Programs that: improve the mechanism of heating prices, heating prices reasonable development of clean, green electricity implement ultra-low emissions coal-fired power plants, a comprehensive clean canceled preferential tariff class of high energy-consuming industries unreasonable prices and other preferential policies. Off Area ban coal stove, substantially eliminated cogeneration heating pipe network coverage in the range of coal heated oven (furnace).

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. Increase Condensing units and cogeneration units technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate coal-fired boilers and scattered inside the pipe network coverage. Actively implement alternative heat source, deadline for shutting down the Guanzhong area below 100,000 kilowatts thermoelectric ratio does not meet the national standard or alternative heat source thermal units. Optimal operation mode cogeneration units, strictly implement the "hot set electricity."

Common thermal efficiency of gas-fired at about 80% -90%, since the exhaust gas temperature at the boiler startup recommendations banks engineering more than 100 deg.] C, with a lot of heat loss of exhaust gas, it is a waste. Condensing gas boiler is to improve the thermal efficiency of the boiler by reducing the exhaust gas temperature, flue gas dew point of 55 ℃ -60 ℃, and the main component of natural gas is methane, a large amount of water when burned above the dew point of the gas, If the exhaust gas temperature is reduced to below the dew point, water vapor in the flue gas will be liquefied in the heat, this part can be recycled heat, it again increases the thermal efficiency of the boiler (flue gases into the cooling water will condense boiler corrosion , requires special corrosion-resistant materials). Usually calculated boiler thermal efficiency is used in the low calorific value, i.e. no latent heat in the flue gas condensing boilers while absorbing sensible heat and latent heat in the flue gas, calculated condensing boiler by Equation thermal efficiency reached 100%, the current maximum thermal efficiency of 108.9%.
