Boiler start-up mode and the time required for rejection of boilers and structure, capacity, type of fuel, heating systems for power plants, climatic conditions and the selected operating mode and so on. Press before the start of the boiler in which hot and cold state is different. May have cold start, warm start and hot start state. Cold Start refers to oil boiler after a long time to repair or spare oil furnace seven million gas saving boiler, in the absence of pressure and temperature and the ambient temperature is close to the start of the case; it means hot start by representing boiler short-term disabled, but also to maintain a certain pressure and temperature to start the case; warm start means the state seems not to disable longer exist totally cool conditions. For oil furnace oil furnace gas energy boiler 9,000,000, generally cold start takes about 6-8h, hot start time for 1-2h, warm start time depending on the actual state of the degree of cooling and industry in the meantime. With high and low pressure bypass system of units, start-up time can be shortened oil furnace, but also can reduce the start of the working fluid loss and heat loss. For DC boiler oil furnace boiler gas saving 5 million, much shorter start-up time of 1: According to the process, to draw heat the process flow diagram (not related to the form and material specifications). 2: Calculate the heat required for the process. 3: The computing system startup time and the heat required. 4: redraw heat flow chart, consider the appropriate safety factor to determine the total power of the heater. 5: decision walnut material and the power density of the heat generating element. 6: determine the form of the heater, size, number. 7: Determine the power and control system of the heater. 9000000 oil furnace gas energy boilers, thermal oil heaters, boilers supplied by Hebei Arts Arts boiler limited liability company.
